用于分布通信信号的方法和设备 For distributing communication signal method and apparatus

技术领域 FIELD

本发明涉及电子通信领域。 The present invention relates to the field of electronic communications. 本发明涉及一种用于分布通信信号的方法和设备。 The present invention relates to a method and apparatus for the distribution of communication signals.

背景技术 BACKGROUND

全局时间同步是格型网络中的固有问题。 Global time synchronization is a lattice network inherent problems. 图1示出一范例格型网络的一部分。 Figure 1 shows a portion of an example lattice network. 该格型网络部分100包括多个协调设备10以及大量从节点20,且通常从节点要比协调设备的数目多得多,并由它们共同构成该通信网络。 The lattice network portion 100 includes a plurality of devices 10 and a lot of coordination from node 20, and usually much more than the number of nodes from the coordination of equipment, by which together constitute the communication network. 从节点20优选的是表示通过协调设备10的网络100相互通信的设备。 From the node 20 preferably is a coordinating device via a network 100 to communicate with each other device 10. 节点20可为便携式的或可固定在某一位置。 Node 20 may be portable or may be fixed at a certain position. 如这里所述,若节点20为可移动的,则该节点可为便携式的、固定的或为便携式的但主要保持在给定位置上。 As described herein, if the node 20 is movable, then the node may be portable, fixed or portable but primarily held in a given position. 因此,可将每个节点20标识为在给定协调设备10的传输范围之内或之外。 Thus, each node 20 can be identified to be within the transmission range of a given coordinate device 10 or outside. 则,根据这里的用法,节点20的标识指该节点20在给定协调设备10的传输范围之内或之外的状态。 Then, according to this usage, identifies the node 20 refers to a state in a given coordinated transmission device 10 or outside the range of the node 20.

每个协调设备10有一内部计时器,用于处理内部通信和数据以及用于协调与网络100中其他从节点20的通信。 Each coordination device 10 has an internal timer for internal communications and data processing and for coordinating communications with the network from node 20 100 Other. 通过以定时信标形式传输的时间数据来协调不同协调设备10中的信标。 By the time the data in the form of a beacon transmission timing to coordinate the different coordination device 10 beacons. 通常每个协调设备10全向传输,但不必需如此。 Typically, each coordinating device 10 omnidirectional transmission, but not necessarily so. 因此,环绕图1中每个设备10的虚线圆圈表示每个协调设备10的传输覆盖区示例。 Thus, each device in FIG. 1 surrounded by a broken line circle 10 represents an example of each coordinator device 10 of the transmission coverage area. 可将这些示意性圆圈所覆盖的区域称为集群30或信标集群。 You can circle the area covered by these illustrative called the cluster 30 or beacon cluster.

在设计这种通信网络100时,应考虑到一些重要特征,尤其是功率消耗和消息开销。 In the design of such a communication network 100 should take into account some important features, particularly the power consumption and message overhead. 由于在电子通信网络中需要低功率通信,因此每个集群30具有有限的传输范围。 Since the need for low power communications in an electronic communication network, each cluster 30 has a limited transmission range. 因此,可通过经由传输集群30和接收集群30间的不同集群中继数据来实现非相邻集群之间的通信。 Therefore, by relaying data transmission via different cluster 30 and cluster 30 receives the cluster to achieve the communication between non-adjacent clusters. 这种结构产生一问题,即如何同步不同集群,以便一个集群的传输不会与另一集群的通信行为相干扰或在时间上发生重叠。 This structure produces a problem, namely how to synchronize the different clusters, so that a cluster of transmission and communication behavior does not interfere with another cluster or overlap in time.

由于这种限制,对无线对等网络信标集群进行分布以使得一个集群不与相邻集群相干扰,不是一件易事。 Because of this limitation, wireless peer network beacons distributed clusters so that a cluster does not interfere with the adjacent cluster, not an easy task. 集中式同步技术如高功率广播和帧分隔分别是两种实现时既需要极大传输功率且消息开销又达到极限的技术。 Centralized synchronization techniques such as high-power broadcasting and frame are both separate transmit power requires great message overhead when implemented in two and also reached the limits of technology. 分布式同步技术如回溯(post-facto)同步也需要极大开销,且只能保证通信时间“瞬时”同步。 Distributed synchronization techniques such as backtracking (post-facto) also requires great synchronization overhead, and can only ensure the communication time "instant" sync. 在最小化通信干扰方面没有得到任何重视。 In terms of minimizing the communication interference does not get any attention.

为更好理解格型网络100中固有的同步问题,现在参照图2,其图示出一简单无线对等网络,该网络具有在不同相邻情形202、204下表示的两个集群30。 To better understand the synchronization problems inherent in the lattice network 100. Referring now to Figure 2, which illustrates a simple wireless peer to peer network, the network has two adjacent clusters 202 and 204 under different circumstances represented by 30. 在情形202下,集群30形成重叠区60,且在情形204下,集群30为不相重叠的。 In the case of 202, the cluster 30 is formed to overlap region 60, and in the case of 204, the cluster 30 is non-overlapping. 在任一情形下,由分别位于每个集群30中心的协调设备1、2协调每个集群30的操作。 In either case, by which are located in the center of each cluster 30 to coordinate the operation of each cluster coordination device 1 30. 每个协调设备1、2周期性地传输信标消息,其为各自集群30中的任何数量的节点40提供定时信息。 1 and 2 each coordinator device periodically transmit beacon messages, which provides timing information for each cluster 30 in any number of nodes 40. 通常,要参与网络通信,该网络中每个节点40必须能够对来自至少一个协调设备1、2的信标消息进行解调。 Typically, to participate in network communication, each node 40 in the network must be able to beacon messages from at least one coordinating device 1 can be demodulated. 由于格型网络通常以对等方式组织,所以许多协议允许协调设备1、2随机选择它们何时传输各自的信标消息。 Because lattice peer networks usually organized, so many protocols allow coordination of equipment 1,2 randomly selected when they transfer their beacon message. 在一显然可能的事件时,即两个相邻协调设备1、2选择相同随机数,或选择与相邻协调设备1、2所选择的数目在时间上十分接近的数目,这种几乎同时的传输可在各自覆盖区重叠处产生覆盖禁区(coverage null)。 When an event is clearly possible, i.e. the two adjacent coordination devices select the same random number 1, 2, or select the number of the selected number of adjacent coordination device 1 is very close in time, which almost simultaneous transmission can produce restricted coverage (coverage null) overlap in their coverage area.

在该上下文中,正如协调设备1、2,相邻是指一种情形,其中任一协调设备可直接互通,或通过由节点和其他协调设备组成的网络间接互通。 In this context, as the coordination device 1, adjacent refers to a situation in which any of the coordination device can communicate directly, or through a network of nodes and other equipment consisting of coordination indirect interworking. 例如,相邻可包括一种情形,即由两个协调设备1、2在它们之间定义或创建一重叠覆盖区60,其中边缘节点50与这两个协调设备通信。 For example, adjacent may include a situation where the two devices 1,2 coordination between them define or create an overlapping coverage area 60, in which the edge node 50 in communication with the two coordination devices. 此外,相邻也可发生在两个协调设备1、2没有重叠覆盖区、但每个在各自覆盖区中有常规节点51、52且这两个节点能相互通信的情况下。 Further, may also occur in adjacent two-coordinator devices 1, 2 do not overlap coverage areas, but each case where a conventional node 51, 52 and the two nodes can communicate with each other in their respective coverage area. 相邻也可包括一情形,即不同覆盖区中的节点相互间不直接通信,而是通过其他节点和/或协调设备互通。 Neighbor may also include a situation where different nodes in the coverage area does not communicate directly with each other, but through other nodes and / or coordination of equipment interoperability.

若相邻协调设备1、2传输相互冲突的信标,则位于重叠区中的任何节点(如图2中的边缘节点50)将不能解调信标消息,且实际上将与该网络分离,由此在该重叠区域中产生覆盖禁区。 If the adjacent beacon transmission coordination of equipment 1,2 conflicting, any node in the overlap region are located (in Figure 2 the edge node 50) will not be demodulated beacon message, and actually separated from the network, The resulting coverage restricted in the overlapping area. 若相邻协调设备1、2传输的信标在非重叠区中相互冲突,则位于非重叠区中的任何节点(如图2中的常规节点51、52)将不能解调信标消息,且相互间将分离而无法通信。 If the coordination device 1 adjacent beacons transmitted conflicting in non-overlapping regions, any node in non-overlapping regions are located will not be demodulated beacon message (FIG. 2 in the regular nodes 51, 52), and The isolated and unable to communicate with each other. 为防止出现这种分离,来自相邻集群的信标消息必须错开以便它们不相互重叠。 To prevent this separation, a beacon message from an adjacent cluster must be staggered so that they do not overlap each other.

有许多算法和技术可用于使这些信标间隔开,但它们通常需要全局同步,借此,一个节点(即该例子中的协调设备1、2、10)负责“主”时钟,且其他每个节点根据该主时钟调整其各自的时钟。 There are many algorithms and techniques may be used to make these beacons spaced apart, but they usually require a global synchronization, whereby a node (i.e. in this example the coordination device 1,2,10) responsible for the "master" clock, and each of the other nodes adjust their own clock according to the master clock. 然而,对多跳网络而言,这种算法产生的消息开销达到极限,因为必须不间断地将同步消息发送到该网络中的每个节点。 However, for multi-hop network, this algorithm produces the message overhead to the limit, since it is necessary to continuously send synchronization messages to each node in the network. 另一选择是使用高功率发射机,通过扩大其覆盖区以包括该网络中的每个节点来维持全局同步。 Another option is to use high-power transmitters, by expanding its coverage area to include each node in the network to maintain global synchronization. 第二种选择就硬件而言,费用是无法接受的,且无法保证处处覆盖到。 The second option in terms of hardware, the cost is unacceptable and can not be guaranteed everywhere covered. 此外,由于无线传感器网络依赖于长电池寿命,任何传输网络必须采用节能且同时有效的定时算法,将由同步差异所引起的传输干扰最小化。 Further, since the wireless sensor network relies on long battery life, any transmission network must use the same time saving and efficient timing algorithm, by synchronous transmission interference caused by the differences is minimized.

在由Elson,J.和Romer,K.发表于Proceedings of the First Workshopon Hot Topics in Networks(October 2002,Princeton,New Jersey,USA)中的文章“Wireless Sensor Networks:A New Regime for TimeSynchronization”证实对动态、对等无线传感器网络而言,能源效率是一极大关注。 .. By Elson, J and Romer, K, published in Proceedings of the First Workshopon Hot Topics in Networks (October 2002, Princeton, New Jersey, USA) in the article "Wireless Sensor Networks: A New Regime for TimeSynchronization" proved to be dynamic , in terms of wireless sensor networks, energy efficiency is a great concern. 可是,作者的结论是适用于因特网中的网络时间协议的传统时间同步方法并不适用于无线传感器网络。 However, the authors concluded that the traditional time synchronization method is suitable for the Internet network time protocol is not suitable for wireless sensor networks. 作者提出无线传感器网中的每个节点维持一不规律时钟,对其每个局部同等方辅以相对频率和相位信息。 OF proposed wireless sensor network each node maintains a irregular clock, each of its side supported by the same local relative frequency and phase information. 尽管该文件讨论了当前系统及其需求和缺点,它没有提供解决该问题的方法,因为用他们的话来说,“在已开发的WSN(无线传感器网络)中,目前还没有任何已证实的时间同步解决方案”([t]here arenot yet any proven solutions for time synchronization in deployed WSNs[wireless sensor networks].Id.at4)。 Although this document discusses the current system and its needs and shortcomings, it does not provide a solution to this problem, because with their words, "(wireless sensor networks) have been developed in WSN, there is no proven time synchronization solution "([t] here arenot yet any proven solutions for time synchronization in deployed WSNs [wireless sensor networks] .Id.at4).

在由Elson,J.、Girod,L.和Estrin,D.发表于Proceedings of the FifthSymposium on Operating Systems Design and Implementation(December2002,Boston,MA,USA)中的文章“Fine-Grained network TimeSynchronization using Reference Broadcasts”提出一新方案,其中节点使用物理层广播向其相邻点发送基准信标,称之为基准广播同步或RBS。 By Elson, J., Girod, L., And Estrin, D., Published in Proceedings of the FifthSymposium on Operating Systems Design and Implementation (December2002, Boston, MA, USA) in the article "Fine-Grained network TimeSynchronization using Reference Broadcasts" propose a new scheme in which the nodes adjacent to its physical layer broadcast beacon transmitting a reference point, called the reference broadcast synchronization or RBS. RBS的基准广播不包含一显式时间戳。 RBS does not contain a reference broadcast explicit timestamp. 相反,接收机使用其到达时间作为比较其各自时钟的基准点。 Instead, the receiver uses it as a comparison of their respective arrival time clock reference point. 这一过程产生一高精度时钟协定,而使用最小能量产生精度缓慢降低的跨广播域的时钟。 This process produces a high-precision clock agreements, while using minimal energy to produce a slow decrease in the accuracy of the clock across the broadcast domain. RBS设计的基本特性是它使一组接收机相互同步,这与其中发射机和接收机同步的传统协议相反。 The basic characteristics of RBS design is that it allows a set of receivers synchronize with each other, which is opposite to conventional protocols in which the transmitter and receiver synchronized.

题为“System and Method for Transmission Scheduling UsingNetwork Membership Information and Neighborhood Information”的美国专利公开文献2002/0167960A1中公布了一种方法和系统,其目的是向信道提供无冲突的包传输。 Entitled "System and Method for Transmission Scheduling UsingNetwork Membership Information and Neighborhood Information" of the United States Patent Publication 2002 / 0167960A1 published a method and system, which aims to provide conflict-free packet transmission to the channel.

因此,需要一种改进的通信网络,其克服了上面提到的与先前格型网络有关的问题。 Therefore, a need for an improved communication network, which overcomes the problems related to the previous lattice network mentioned above.

具体实施方式 DETAILED DESCRIPTION

尽管说明书是以定义本发明的被认为是新颖的特征的权利要求书作为结束,相信从结合附图的下面描述中会更好地理解本发明,其中相同标记编号接后。 While the specification is based on the definition of the present invention is considered to be novel features of the claims of the requirements as the end, I believe from the following description in conjunction with the drawings will be better understanding of the present invention, wherein the same reference numbers connected after.

下面首先详细参照附图,尤其是其中的图3,它图示出了在相邻情形202下与图2中的两集群网络相对应的信标时序图300。 First, in detail below with reference to the drawings, in particular the Figure 3, which illustrates a case 202 adjacent in Figure 2 under the two corresponding cluster network beacon timing diagram 300. 图3图示出集群30的协调设备1、2的信标时间随时间漂移得越来越近的情形。 Figure 3 illustrates the cluster coordination device 30 1,2 beacon time drift over time more and more close to the situation. 具体而言,在网络中的给定瞬间时刻t1,其在此处被表示为“超帧”,协调设备1、2的信标时间在时间上彼此分离地开始。 Specifically, in the network at a given instant in time t1, which is expressed as "super frame", 1,2 coordinator device beacon time begin to separate from each other in time here. 在对等格型网络中,信标时间漂移302通常是固有的,因为每个协调设备1、2没有与任何或所有其他协调设备1、2严格相同的内部时钟。 Lattice peer networks, the beacon 302 is typically inherent drift over time, because each device 1,2 no coordination with any or all of the other devices 1,2 coordinate the exact same internal clock. 根据这种特征,超帧t2至tn表示协调设备2的、向协调设备1的信标时段漂移的信标时段。 According to this feature, the superframe t2 to tn denote coordinator device, the coordinator device beacon period a drift beacon period 2.

由于协调设备1、2不在彼此范围之内,所以它们无法彼此直接通信,以保持相互间隔离开。 Since the coordinating device is not within range of each other 1, 2, so that they can not communicate directly with each other, in order to maintain spaced away from. 另一方面,它们确实享有可用来分隔它们信标的某些共同地方,具体来讲是边缘节点50。 On the other hand, they do enjoy the beacons can be used to separate them some common places, specifically edge node 50. 根据本发明,节点50检测协调设备1、2的信标,并与协调设备1、2通信。 1,2 communication according to the present invention, the node device 50 detects the coordinate of the beacon 1, and with the coordinating device. 根据本发明,该通信用于提示对协调设备1、2中其一或两者作调整。 According to the present invention, the communication device 2 for prompting the coordination adjusted in either or both. 根据所检测信标特征,例如可以以图3中所示的漂移校304来进行调整。 According to characteristics of the detected beacon, for example, to drift correction 304 shown in FIG. 3 to be adjusted. 因此,超帧tn+1表示协调设备2的一信标时段,该协调设备2已经通过将其时段相对于协调设备移回移出而得以校正。 Thus, superframe tn + 1 represents a coordinator device beacon period 2, the coordinating device 2 has passed its time period with respect to the coordination of equipment which can be moved back out of calibration.

边缘节点50被置于协调设备1和2的集群30的重叠区。 The edge node 50 is placed in the cluster coordinator device 1 and 2 overlap region 30. 在该位置上,边缘节点50可收到来自协调设备1和2的信标消息。 In this position, the edge node 50 can receive the beacon message from the coordinator device 1 and 2. 有了这个信息,通过应用本发明,边缘节点50可确定信标消息的预定特征。 With this information, by applying the present invention, the edge node 50 can determine a predetermined characteristic of the beacon message. 例如,边缘节点50可注意到漂移、可确定漂移速率、和/或可确定来自协调设备1和2的信标消息的接近程度(即时间上的靠近度)。 For example, the edge node 50 can be noted that drift, the drift rate can be determined, and / or may determine a beacon message from the coordinator devices 1 and 2 of the degree of proximity (i.e., time on the near degrees). 响应于确定了特征,边缘节点50可发送一提示,向协调设备1和2警告信标重叠或出现重叠之前的信标接近程度。 In response to determining the characteristics, the edge node 50 can send a prompt to coordinate devices 1 and 2 warning beacon beacon overlap or appear before approaching the degree of overlap. 通过令边缘节点50能够向协调设备2警告其信标正向协调设备1的信标漂移,协调设备2可将其自身时钟向前推进给定漂移量,并防止任何通信重叠。 Through edge node 50 can make to coordinate its beacon warning device 2 forward coordination beacon device a drift, coordination device 2 can be given its own clock drift forward and prevent any communication overlap. 此外,在超帧tn+1的情形中示出了校正后的情形304,其中协调设备1和2的信标消息在时间上不重叠。 Further, in the case of a superframe tn + 1 is shown in the case of the corrected 304, wherein the beacon message coordination device 1 and 2 do not overlap in time.

边缘节点50可包括处理器,其被编程以执行根据本发明的方法。 Edge node 50 can include a processor, which is programmed to perform a method according to the invention. 例如,可对该处理器编程以检测相邻协调设备1、2的信标消息,并确定是否存在重叠情形。 For example, the processor can be programmed to detect neighbor coordinator device beacon messages 1, 2, and determines whether there is overlap situations. 若存在这种情形,则从节点50发出一提示,向两个相邻协调设备1、2中至少其一警告该情形。 If there is such a case, the node 50 from issuing a prompt, coordinated to two adjacent devices 1 and 2, at least one warning the situation. 该警告提示给协调设备1、2中至少其一发信号以对其定时作出校正调整。 The warning device to coordinate 1,2 least make it out of the correction signal to adjust their timing. 例如,协调设备1或2可按一校正量调整其各自信标消息的开始时间。 For example, the coordination device 1 or 2 according to a correction amount to adjust the start time of its confidence of the beacon message.

替换地,也可将第一和第二协调设备1、2分别置于第一和第二非重叠协调设备覆盖区30内,正如在图2的相邻情形204中所看到的。 Alternatively, it may be the first and second coordination device 1 were placed in the first and second non-overlapping coverage areas coordinating device 30, as in the case 204 adjacent as seen in Figure 2. 这里再次说明,根据本发明,所述至少两个协调设备1、2正在传输信标消息,且分别位于第一和第二协调设备覆盖区的至少两个常规节点51、52能够检测信标消息中的预定特征。 Here again, according to the present invention, the at least two coordinated transmission devices 1, 2 is a beacon message, and are located in a first coverage area and the second coordinate of the at least two device nodes 51, 52 is able to detect conventional beacon message predetermined characteristics. 响应于所检测出的特征,节点51、52中的至少一个将一提示发送给协调设备1、2中的至少一个。 In response to the detected feature, at least one of the nodes 51, 52 will send a prompt to the at least one device 1 of coordination. 正如图3的时序图中所见,响应于该提示,所述第一和第二协调设备1、2中的至少一个根据该提示作出调整,例如漂移校正304。 As to the timing chart of Figure 3 seen in response to the prompt, the at least one adjusted based on the tips of the first and second coordination device 1 and 2, for example, drift correction 304. 因此,重新确立了时间同步,以允许通信。 Therefore, re-established the time synchronization to allow communication.

根据本发明的优选实施例,可在下面的示意性分布算法中解释该校正:IF my_beacon_time-beacon_time(neighbor)<Guard_TimeTHEN my_beacon_time=my_beacon_time+Tshift,其中: According to a preferred embodiment of the present invention, may be explained in the following exemplary distribution algorithm correction: IF my_beacon_time-beacon_time (neighbor) <Guard_TimeTHEN my_beacon_time = my_beacon_time + Tshift, wherein:

my_beacon_time为协调设备2;beacon_time(neighbor)为协调设备1;Tshift=2*dT;以及dT=beacon_time(neighbor)+Guard Time-my_beacon_time。 my_beacon_time to coordinate equipment 2; beacon_time (neighbor) to coordinate equipment 1; Tshift = 2 * dT; and dT = beacon_time (neighbor) + Guard Time-my_beacon_time.

该分布算法适合任何规模的网络。 The distribution algorithm for the network of any size. 同样,该算法不受到将Tshirt定义为等于2倍dT的限制。 Similarly, the algorithm will not be defined as equal to twice Tshirt dT limit. 应理解该例子是一优选实施例,且Tshift可等于或大于dT。 It should be understood that the examples are a preferred embodiment, and may be equal to or greater than Tshift dT.

为说明本发明算法的灵活性,检查图4所示的三集群网络以及图5所示的相应信标时序图。 To illustrate the flexibility of the present invention the algorithm, to check the corresponding beacon timing diagram shown in Fig 4 and three cluster network shown in Fig. 在该例子中,假定集群协调设备1和集群协调设备2正向彼此漂移,类似于图3例子中的情况。 In this example, assume that the cluster coordinator device 1 and device 2 forward each cluster coordinator drift, similar to the case of the example in Figure 3. 此外,在该例子中,协调设备3的第三集群被定义为以与协调设备2的集群几乎相同的速率、并沿相同的方向进行漂移。 Further, in this example, the third coordinator device 3 is defined as a cluster with the cluster coordinator device 2 is almost the same rate, and drift in the same direction. 据此,超帧t2至tn表示均正向协调设备1的信标时段漂移的协调设备2和3的信标时段。 Accordingly, the superframe t2 to tn denote both the forward coordinating beacon period apparatus drift coordinator device beacon period 2 and 3. 最后,该例子假定协调设备2和3彼此最初在时间上分隔大于Guard_Time的期间。 Finally, this example assumes that the coordination device 2 and 3 are separated from each other in the time period originally greater than Guard_Time.

在每个超帧期间,该网络中至少一个协调设备运行分布算法,并作出任何必需的定时校正。 In each super-frame period, the network equipment operating at least one coordinating distribution algorithm, and make any necessary timing correction. 对超帧t1和t2而言,3个协调设备1、2、3都不作任何校正,因为对每个协调设备所作的计算my_beacon_time-beacon_time(neighbor)大于Guard_Time。 The superframe t1 and t2, 2, 3, 3 coordination does not make any correction, because each coordinate computing device made my_beacon_time-beacon_time (neighbor) is greater than Guard_Time. 然而,在超帧tn期间,边缘节点50通知协调设备2(直接或间接)my_beacon_time与beacon_time(neighbor)之间的差比Guard_Time小dT2的时间。 However, during superframe tn, the difference between the edge node 50 inform the coordinator device 2 (directly or indirectly) my_beacon_time with beacon_time (neighbor) between Guard_Time smaller than dT2 time. 因此,在下一超帧期间,协调设备2调整其信标与协调设备1所传输的信标分开等于2倍dT2的时间(2只是一个作为示意性实施例的倍数)。 Thus, during the next super frame, a beacon coordinator device 2 to adjust its beacon transmission and coordination device 1 separately dT2 time equal to two times (2 merely as an illustrative embodiment of a multiple). 然而在作出调整时,边缘节点50在超帧tn+1中检测到现在协调设备2和3正在相当危险地相互靠近。 However, when adjusted, the edge node 50 detects superframe tn + 1 to the current coordinate in the device 2 and 3 are quite dangerously close to each other. 因此,边缘节点50通知协调设备3(直接或间接)调整其信标与协调设备2所传输的信标分开等于2倍dT3的时间。 Thus, the edge node 50 inform the coordinator device 3 (directly or indirectly) to adjust its beacon transmission and coordination device 2 separate beacon time equal to twice dT3. 具体而言,在下一超帧tn+2期间,协调设备3调整其时钟,从而使协调设备3不受到干扰。 Specifically, in the next super frame period tn + 2, the coordination device 3 to adjust its clock so that the coordination device 3 are not disturbed. 尽管该例子十分简单,且只利用一边缘节点,但可将该概念扩展到多个集群以及多个边缘节点。 Although this example is very simple and uses only one edge node, but the concept can be extended to multiple clusters and multiple edge nodes.

图6中示出一种更复杂的情形。 Figure 6 shows a more complex situation. 这里,将7个集群30组织形成不同的信标覆盖重叠。 Here, the seven clusters 30 different tissue formation beacon coverage overlap. 像之前那样,假定协调设备1至7随机选取各自的信标时间,其可能或可能不与另一协调设备的相邻集群30的信标时间重叠。 As before, it is assumed coordinator device 1-7 randomly selected respective beacon period, which may or may not overlap with another cluster adjacent to the coordinating device 30 of the beacon period. 即使所有协调设备1至7选取了不同信标时间,但由于非理想的时钟漂移特性,相邻集群30的信标时间会随时间向彼此漂移。 Even if all the coordination device 1-7 to select different beacon time, but due to non-ideal clock drift, the adjacent cluster beacon period to another 30 will drift over time. 若每个协调设备1至7运行上面提到的根据本发明的时间分布算法,则可完全消除信标重叠。 If each coordinator device 1-7 mentioned above run time distribution algorithm according to the present invention, can completely eliminate the beacon overlap.

为简单起见,只使用仿真的初始和最终时序图来解释对于图6中的七集群网络的根据本发明的算法。 For simplicity, the simulation using only the initial and final timing diagram in Figure 6 is explained for seven cluster network algorithm according to the invention. 图7是图6中的七集群网络的初始时序图。 6 in Fig. 7 is a timing chart of the initial seven cluster network. 在图7的例子中,假定所有协调设备1至7已随机选择它们各自的信标时间。 In the example of FIG. 7, it is assumed that all coordination devices 1-7 have their respective randomly selected beacon time. x轴表示时间,且y轴表示感兴趣的协调设备区或集群号码。 x-axis represents time, and the y-axis represents the coordination device area of interest or a cluster number. 在该例子中,有3个感兴趣区,其中一些需要校正。 In this example, there are three regions of interest, some of which needs to be corrected. 将逐个进行讨论。 Will be discussed individually.

在图7中,协调区7显示协调设备3、4、6和7的信标时间。 In Figure 7, the coordination area coordination device 3,4,6 and 7 show the beacon time 7. 检查图6中的网络图发现协调设备3、4和6与协调设备7有共同的覆盖区。 Check network diagram in Figure 6 discovery coordinator device 3, 4 and 6 and 7 have a common coordination device coverage area. 因此,为防止集群间干扰,必须从时间上将这4个协调设备分开。 Therefore, in order to prevent inter-cluster interference, this must be coordinated from the time four separate devices. 注意到协调设备3的当前信标时间与协调设备7的信标时间重叠。 Noting the current beacon time coordination of equipment and coordination equipment beacon overlap time of 7 3. 必须校正该重叠。 Must correct the overlap. 协调区7还呈现出协调设备3的信标时间与协调设备4的信标时间危险地靠近,换言之,这些信标并没有至少分开Guard_Time。 District 7 also presents coordination coordination device beacon for 3 and 4 of the beacon device coordination dangerously close to the time, in other words, these beacons are not at least separate Guard_Time. 因此,为防止重叠,必须将协调设备3和4的信标在时间上安全分开。 Therefore, to prevent overlap, the device must be coordinated beacons 3 and 4 are separated in time safety.

最后,检查协调区5。 Finally, check the coordination zone 5. 如所期望的,协调区5“收听”来自协调设备1、2和6的信标。 As expected, the coordination area 5 "listen" to the beacon from the coordinator device 1, 2 and 6. 协调设备1的当前信标时间被显示为与协调设备6的当前信标时间重叠。 Coordination device current beacon time is displayed as a coordination device current beacon time overlapping 6. 然而,由于协调设备1和6的覆盖区不重叠,不需要执行任何校正动作。 However, since the coverage area coordinator device 1 and 6 do not overlap, do not require any corrective action.

图8示出在本发明的仅仅几次迭代后的最终时序图。 Figure 8 shows after only a few iterations of the present invention the final timing diagram. 通过以相应协调区的函数的形式从时间上将每个信标消息分隔,本发明的算法成功地防止重叠,而没有任何相当大的消息开销,不必连续发送同步消息给该网络中的每个节点,且不需高功率发射机。 In the form of a function by the corresponding coordination area separated from each beacon message will time, algorithm of the present invention successfully prevent overlapping, without any substantial message overhead, without having to continuously send synchronization messages to the network each nodes, and does not require high-power transmitter. 如先前提到的,以往技术中使用高功率发射机通过扩展其覆盖区以包括该网络中的每个节点来维持全局同步。 As previously mentioned, the use of high power transmitters by expanding its coverage area to each of the nodes of the network to maintain global synchronization in the conventional technique. 因此,已获得重大受益。 Therefore, has been a major benefit.

如上面所述,当两个协调设备没有重叠覆盖区时,定时信标可有任意大小的定时重叠。 As mentioned above, when the two devices do not have overlapping coverage area of coordination, timing beacon may have overlapping timing of any size. 图8示出设备1和4在x轴时间″9″处共享同一传输时间的情况。 Figure 8 shows a status of the device 1 and 4 share the same transmission time on the x-axis time "9" at. 这是可接受的,因为协调设备1和4的集群物理上不相重叠。 This is acceptable because the physical coordination device cluster 1 and 4 on non-overlapping.

对于可监视多个信标消息以便向信标协调设备1至7通知可能的干扰问题的节点50,使用从节点50获得的知识允许实现比以往技术中的分布式或集中式时间同步算法简单得多的分布式定时算法。 For a node can monitor multiple beacon to beacon messages to coordinate equipment 1-7 notification of possible interference problems 50, using the knowledge gained from node 50 allows for simpler than conventional technologies for distributed or centralized time synchronization algorithm was Distributed multi-timing algorithms.

可将本发明的算法调整用于适合任何规模的网络。 The algorithm can be used to adjust the present invention is suitable for networks of any size. 适配该算法的仅有参数包括“分隔帧大小”和Guard_Time。 The only parameter adaptation algorithm includes "separated frame size" and Guard_Time. 将分隔帧大小定义为分隔每个信标传输所需的时间量。 The amount of time will separate the frame size is defined as a separate each beacon transmissions required. 对低工作周期操作而言,分隔帧时间可很大,如图9中所示。 Low duty cycle operation, the time frame may be separated by a large, as shown in FIG. 需要更频繁的通信的应用可配置很小的分隔帧,如图10中所示。 Require more frequent applications can be configured to communicate a small partition frame, shown in Figure 10.

本发明的定时算法不仅限于包含边缘节点的节点网络。 Timing algorithm of the present invention is not limited to nodes of the network comprises edge nodes. 也可将该算法应用于一网络,其中相邻集群中的节点相互通信以共享与它们各自的集群有关的时间信息。 The algorithm can also be applied to a network, the time information of the cluster nodes communicate with each other to share their respective clusters associated with adjacent. 在这种实施例中,独立节点51、52(可能是物理上足够靠近来相互通信的两个节点)可通知两个相邻的不同协调设备1、2之间的迫近重叠,以及分别与相邻协调设备10通信以协调它们集群的信标时间。 Respectively phase In such an embodiment, the individual nodes 51 and 52 (two nodes may be close enough to physically communicate with each other) may notify the impending overlapping two adjacent different coordination between the devices 1,2, and o coordinating communications device 10 to coordinate their cluster beacon time.

图11是一流程图150,其概括如何根据本发明以下列步骤进行通信信号调整:检测信标消息152、确定信标消息154中的特征、响应于特征156将提示发送给协调设备、以及响应于提示158在协调设备处作出调整。 Figure 11 is a flow chart 150 that summarizes how these steps to adjust the communication signal according to the present invention: detecting a beacon message 152, determines the beacon message 154 features, feature 156 in response to prompts sent to the coordinator device, and in response 158 tips to make adjustments to the device in the coordination office. 因此,在一格型网络中,由代理检测、确定、以及提示,从而使协调设备作出调整。 Thus, in a lattice network, by proxy detection, OK, and tips to make adjustments so that the coordination of equipment. 参照图1、2和3,这意味着在图1的格型网络100中,由代理(即图2所示边缘节点50或常规节点51、52)检测、确定、以及提示,从而使协调设备1、2作出调整,如图3中的调整304。 Referring to Figures 1, 2 and 3, which means that in the lattice network 100 of Figure 1, by an agent (i.e., the edge node 50 shown in Figure 2 or conventional nodes 51, 52) for detecting, determining, and the tips, so that the coordination device 1,2 adjustment, the adjustment 304 shown in Figure 3. 该方案自身在格型网络100不断重复,以为协调设备间提供改进的通信。 The program itself is repeated at 100 lattice network devices that provide improved coordination between communications.
