Description
Technical field
The invention belongs to deep space communication emulation field, relate to a kind of distributing emulation system towards the many repeater satellite communications of deep space.
Background technology
Deep space communication is the important leverage that survey of deep space task is implemented smoothly, and it is faced with and the distinct difficult problem of communicating by letter of traditional terrestrial wireless communication, for example: long transmission distance, path loss is large, and propagation delay is long, the frequent interruption in chain Louis etc.
Because survey of deep space experiment is difficult for carrying test, good emulation platform can, the communication link under accurate simulating deep space environment, analyzes and tests relevant technology and theory, is the necessary guarantee that deep space communication research is carried out.
Current more popular following four sections of network simulators:
1) NS2:NS2 (Network Simulator version 2) network simulator is a kind of OO network simulator.NS2 software is furnished with simulation process dynamic watcher, can after simulation run finishes, dynamically watch the running of emulation, observes the data of following the tracks of.NS2 is powerful, and extensibility is strong, and execution efficiency is high, has been widely used in the emulation of local area network (LAN), wide area network, wireless mobile network and satellite network.
2) OMNeT++:OMNeT++ is a kind of Discrete Event Simulator, possesses insertion type simulation kernel and powerful graphical interfaces interface, can run on a plurality of operating system platforms, possesses programming, and the functions such as debugging and tracking support are also supported distributed parallel emulation.
3) DTNsim:DTNsim is the discrete event simulator of writing with Java language, and the message stores while being used for the middle Transmission of analog D TN (Distributed Transient Network, the transient network of distribution) or failure forwards.DTNsim also supports the burst of message to transmit.If encounter connection closed in a message transport process, and had the success of message burst to be received by node, this node will be waited for the arrival of remaining message burst so.
4) ONE:ONE is applicable to the Routing Protocol of DTN network environment and the simulator that application study is analyzed, and has the feature of discrete event driving, object-oriented and Reality simulation network environment.ONE integrates mobility model, DTN route and visual graphical interfaces, is very easy to expand, and a large amount of analytical model and report the tests can be provided.
Although there is very outstanding simulation performance in Zhe Si money simulation software, when the data communication package of emulation survey of deep space, exist the shortcoming that cannot go beyond:
1) NS2 lacks DTN network environment is well supported.Meanwhile, when NS2 carries out multinode emulation, can not transmit real data, this causes carrying out the transmission of True Data.
2) OMNET++ needs user oneself to realize specific function.Meanwhile, when the extensive node of NS2 experiment simulation, can not transmit True Data, can only transmitting data information.
3) DTNsim is specially for the simulator of DTN Environment Design.But it just merely pays close attention to the emulation of route.Meanwhile, when multinode emulation, can not carry out the transmission of True Data.
4) ONE network simulator has only been realized the BP part of DTN agreement, when carrying out multinode emulation, just transmits virtual data (information of data message), can not realize True Data transmission and can not embody data flow.
In sum, NS2 and OMNET++ network simulator lack DTN network environment good support, need user specifically to develop.Although and DTNsim and ONE network simulator are to be the simulator of DTN Environment Design specially, have defect separately.And when multinode emulation, it all can only simulate virtual data transmission, can not carry out True Data transmission, can not meet the requirement of deep space protocol emulation, cannot realize deep space protocol emulation.

Embodiment
Below in conjunction with accompanying drawing explanation and embodiment, the present invention is further described.
Difficult point of emulation deep space DTN Internet Transmission is to provide in real time emulation link data.Analogue system of the present invention is introduced external deep space scenario simulation software satellite kit (STK), and configuration needs the deep space scene of emulation, automatically produces in real time the information such as each internodal link information and tracks variation, for emulation provides true link information.
Distributed Simulation Platform based on HLA, analogue system multinode analog communication process of the present invention, index extraction and dynamically demonstration in real time.As shown in Figure 1, analogue system of the present invention consists of five federal members, respectively: survey of deep space federal member, relay satellite federal member (2), ground station's federal member, deep space environment federal member and collection scheduling federal member.A plurality of via nodes of wherein, jumping by alternately simulation difference of two relaying federal members (I, II) complete transfer of data.
Each federal member of analogue system of the present invention is as follows:
Survey of deep space federal member: realize Data Collection, and the agreement of emulation as required or encoding scheme process to data, then send, backward target is relay satellite federal member (n).Effect in whole analogue system is: 1. the collection of detection data; 2. according to concrete agreement or encoding scheme, data are processed; 3. data flow transmitting terminal, backward contact is relay satellite federal member.
Relay satellite federal member (I, II): the transmission trunking in communication process, the effect of relay satellite federal member is: realize the effect of signal amplification forwarding 1.; 2. embody the performance of each relay satellite, state; 3. data flow intermediate link, final forward direction node is probe satellite federal member, final backward node is ground station's federal member (multistage).
Ground station's federal member: be detection data receiving terminal in whole analogue system, realize the Recovery processing work of detection data.The effect of ground station's federal member is: 1. data flow recover detection data according to corresponding coding or agreement in receiving system; 2. the terminal of data flow in system, its forward direction node is relay satellite federal member.
Deep space environment federal member: play very important effect in whole analogue system, it has guaranteed, whole simulation process carries out in real deep space environment, and this federal member is complementary member, does not participate in the transmission of data flow in analogue system directly.Deep space environment federal member generates after these deep space environment data, in real time these data is upgraded in whole artificial network.The effect of deep space environment federal member is: produce in real time deep space environment data and by the mode of broadcast, make each federal member in system carry out real-time update to data.
Data acquisition scheduling federal member: realize record storage and the multinode transmission route of simulation process data parameter are selected, the control member that this federal member is system emulation, does not participate in flowing of emulated data stream directly.For example link information, the current transmission progress of data and Route Selection between node.The effect of data acquisition scheduling federal member is: realize the pick up and store to analogue system performance data 1.; 2. the encoding scheme of pair emulation or the protocol scheme performance in emulation is given and preliminary judgement.
Highlight the realization of many via nodes of emulation networking transmission below, mainly comprise following three aspects:
The realization of (1) two trunk module
In order to embody True Data, flow, be easy to simulation demo platform subsequent development (such as increasing hardware channel module), each via node should be realized separately (as a computer is realized a node), runs into like this difficult point: during many via nodes of emulation, need to expend great amount of hardware resources.The present invention proposes to utilize two trunk module simulations to realize the transfer of data of a plurality of via nodes, completes emulation.Two trunk modules are identical in essence, serve as different roles during just due to simulation multinode.Just in single, then say and should have: store and forward function, and adjust in real time message transmission rate according to the characteristic of link; The function with simulation multinode.
Accompanying drawing 2 is that two trunk modules are simulated many relayings implementation procedure.Simulating scenes is that Mars sends data, and the store and forward through Mars repeater satellite (2, A and B)-moon repeater satellite (C)-earth repeater satellite (D), finally arrives earth base station.Total process is divided into four sections of transmission, supposes that red link is for determining Route Selection (being Mars-A-C-D-earth).
Utilize two trunk modules (I and II) to simulate whole trunk network (A, B, C and D), complete many via nodes segmentation cooperation transmission.Specific implementation process: the operation of deep space communication scene, probe satellite (mars exploration car) sends data to Mars repeater satellite A, now with trunk module I simulation A, receives data; Store and forward, to down hop moon repeater satellite node C, now receives data with trunk module II simulation C, and store and forward is to down hop earth repeater satellite node D; Now, trunk module I holds two duties, in simulation A, simulates earth repeater satellite D, receives the data of sending from a upper node C, and store and forward is to down hop earth base station, and final earth base station receives data and completes whole deep space communication emulation.The advantage of such scheme is: compare with directly realizing many relayings, save hardware resource; With with the simulation of single trunk module, compare, embody True Data and flow, be easy to subsequent expansion.
(2) realization of deep space environment module
The topological diagram information of deep space environment module based on receiving, configures the true transmitting scene of corresponding deep space.By simulating deep space real scene, for platform provides deep space link information in real time, mainly comprise: the link in deep space DTN network between each object is communicated with situation (link break-make), link-quality (error rate) and link range etc. in real time.
Utilize STK simulate whole from mars exploration car through junction network, finally arrive each celestial body of link level simulation of earth base station and its satellite etc.This deep space environment scene comprises:
Celestial body, has Mars and the earth, is respectively used to carry mars exploration car and earth base station;
Satellite, by a certain amount of Mars repeater satellite, moon repeater satellite and earth repeater satellite, has formed junction network, is responsible for data to carry out store and forward;
Mars exploration car and earth base station, transmission and last reception of being responsible for data.
Below the deep space environment scene that has substantially just contained required emulation, wherein celestial body, mars exploration car and earth base station are fixed, and for each scene, are the same.Because the kind of repeater satellite and the difference of quantity have brought up the difference of last deep space environment DTN network scenarios, thereby also brought up emulation platform can emulation arbitrarily (based on truth, should be within the specific limits) deep space environment of relay scene, strengthened the extensibility of emulation platform.
(3) realization of collection scheduling module
Be unableing to do without in order reasonably of many relayings multi-hop segment transmissions dispatched.Based on to the current transmission link information of Real-time Collection and transmission progress analysis, specified data transmission route, ensures that multinode relay transmission effectively reliably completes.Analogue system of the present invention provides Route Selection interface, can be for freely realizing specific routing algorithm.
Collection scheduling module, as the core of analogue system of the present invention, has center leading position.On the one hand, be responsible for gathering the real-time related data (such as the percentage that current data transmits, the link information between each data transmitter etc.) of current emulation platform operation, show in real time; On the other hand, the data that gather are effectively analyzed, made relevant decision-making (such as control data transmission situation), make whole platform carry out effectively really data transmission.
Collection scheduling module mainly realizes by following four aspects:
A. according to topological structure, automatically set up corresponding real scene, emulation deep space communication environment, provides link information in real time.
B. scheduler module is according to the link information and the data transmission state that gather, position relationship between real-time update topology diagram and each object.
C. according to current topological structure figure, determine in real time transmission route, complete scheduled transmission.Because via node receives data, receive and send out (receive after data at once store and forward to down hop via node), so selecting route is determining at the very start, the routing strategy that this platform is taked is: first, select next-hop node have link as transmission node, but, when down hop has the node of link, have when a plurality of, chosen distance nearest as transmission node.Certainly, complicated routing algorithm also can be realized in analogue system of the present invention.
D. gather current data transmission progress and transmission rate, show in real time.
Under the scheduling of data acquisition scheduling federal member, by relay satellite federal member I and relay satellite federal member II alternately realize each jump in different a plurality of via nodes be specially: data acquisition scheduling member according to definite scene information (be mainly the scene information of trunk network, as " 3-2-4; "), be broadcast to each data module.Relay satellite federal member I and relay satellite federal member II receive after scene information, carry out the coupling of corresponding scene: the via node that is positioned at odd positions corresponding to relay satellite federal member I simulation, as " 3 " and " 4 "; Corresponding, the via node that is positioned at even number position corresponding to relay satellite federal member II simulation, as " 2 ", thereby determines the attribute in relay satellite federal member I and II simulation multi-hop relay on the whole.And then, collection scheduling federal member is by link information between each node of gathering simulation scene (link break-make and distance etc.), according to this, determine that (selection of transmission route algorithm can independently define transmission route, here the segment transmissions of simple 1 pair 1 of selecting, selects the node of first selecting to be communicated with from down hop link; If it is a plurality of that the node that link is communicated with has, that nearest node of chosen distance), thus determine and respectively jump selected node on a plurality of nodes, reinform to relaying I and II.Part, relay satellite federal member I and relay satellite federal member II have just determined the concrete node identity of the own nodal community of realizing like this.Thereby under the scheduling of data acquisition scheduling federal member, by relay satellite federal member I and relay satellite federal member II, alternately realize different a plurality of via nodes in each jumping and simulate.
The emulation CFDP agreement of take is example, simple declaration simulation process:
CFDP agreement is flexible, the efficient space channel Data Transport Protocol that international space data system Advisory Board (CCSDS) suggestion is used.CFDP is the file storage based on actual, and agreement can be used at inter-entity transmission data block.Analogue system of the present invention adopts and postpones negative type CFDP agreement, and its transporting mechanism as shown in Figure 3.
The workflow of analogue system of the present invention as shown in Figure 4.This flow chart is to take the file transfer protocol (FTP) (delaying type CFDP) of CCSDS suggestion to design as artificial tasks.
Analogue system of the present invention is used C++, interface to realize with MFC.Simulating scenes is:
From accompanying drawing 5, can clearly see in data acquisition scheduling federation, real-time update simulation space DTN network topology structure (upper left), show each section of link of current transmission route link information (under) and gather display image data real-time Transmission progress (upper right).
Emulation conclusion:
U analogue system has successfully completed the emulation of CFDP agreement, and actual emulation number of retransmissions is consistent with theoretical value.
U learns through Multi simulation running, in deep space communication transfer of data, utilizes many relayings multi-hop networking transmission, higher than the efficiency of the point-to-point transmission of single relaying.
