附图说明 Brief Description

[0018] 图1为本发明一个实施例的流程图。 [0018] Figure 1 is a flow diagram of one embodiment of the invention.

具体实施方式 DETAILED DESCRIPTION

[0019] 下面结合附图对本发明作进一步阐述。 [0019] the following with reference to the present invention will be further described.

[0020] 如图1所示,其为循环流程图,本发明一个实施例应用于W1-Fi网络的无线数据传输自动调整方法,其具体步骤为:在W1-Fi网络中,数据发送方和接收方通过CSMA/CA机制(载波侦听多路访问/冲突避免)获得传输权限进行网络数据传输。 [0020] Figure 1, which is a circular flow diagram, an example applied to W1-Fi wireless data transmission network to automatically adjust the method of the present invention, the specific steps: In W1-Fi network, the data sender and receiver via CSMA / CA mechanism (Carrier Sense Multiple Access / Collision Avoidance) obtained permission to transfer network data transmission. 无线网络的发送方发送802.11封包数据给接收方,所述发送方可解释为W1-Fi网络发送设备,进一步的,W1-Fi网络发送设备是无线AP、工作站、在W1-Fi网络中运行的无线设备中的一种;接收方可解释为W1-Fi网络接收设备。 The sender sends 802.11 wireless network packet data to the recipient, the sender can be interpreted as W1-Fi network to send equipment, further, W1-Fi network transmission device is wireless AP, workstation, running in W1-Fi network A wireless device; recipient may be interpreted as W1-Fi network reception device. 接收方回复Block ACK信号确认接收情况,同时,无线网络中的发送方根据所发送的数据包大小、发送次数以及收到接收方成功接收到的数据信息,分析无线数据传输重传率和实时速率情况,判断网络环境的变化。 Recipient replies Block ACK reception confirmation signal, while the wireless network based on the sender sent the packet size, the number of transmissions and receive recipient successfully received the data, analyze wireless data transmission retransmission rate and real rate case, change to determine the network environment.

[0021] 在判定网络环境发生变化时,发送方启动数据传输自适应算法:当环境变差时,提高天线增益,使用Long GI (长数据保护间隔),降低MCS (调制解调机制)速率等级;当网络环境变好时,降低天线增益,使用Short GI (短数据保护间隔),提高MCS (调制解调机制)速率等级。 [0021] In determining the network environment changes, the sender initiates the data transfer adaptive algorithm: when the environment deteriorates, improve the antenna gain, using Long GI (guard interval length data), lower MCS (Modulation demodulation mechanism) speed rating ; when the network environment changed for the better, the lower the antenna gain, the use of Short GI (short guard interval data), improving MCS (Modulation demodulation mechanism) speed grades.

[0022] 同时,在驱动配置文件中,针对每个MCS速率等级单独配置BAWinSize (块应答窗口),保证当MCS等级发生变化时,BA长度随之发生自适应性调整。 [0022] Meanwhile, in the drive configuration file for each rate class MCS configured separately BAWinSize (block acknowledgment window), to ensure that when the MCS level changes, BA length ensues from adaptation. 如MCS等级较高时,说明网络环境良好,可以支撑高速的数据传输,此时调用与MCS适应的高BAWinSize,可以有效节省系统开销,充分利用优良的环境进行数据传输;在MCS等级降低时,判断网络运行能力减弱,为了减轻网络系统负担,也随之调用低BAWinSize。 MCS as higher grade, indicating a good network environment, you can support high-speed data transmission, this time to call MCS adaptation and high BAWinSize, can effectively reduce system overhead and take advantage of an excellent environment for data transmission; when lowered MCS level, diminished capacity to determine the network running, in order to reduce the burden of network systems, also will call low BAWinSize.
