The Research And Simulation Of Massive Ad Hoc Networking Technology

The wireless Ad Hoc network has the characteristics of no infrastructure,flexible networking,and high survivability.It is widely used in military and civilian scenarios and has a very good development prospect.With the deepening of research on Ad Hoc network networking technology and the development of simulation tools,the demand for realization of its intelligent research and simulation is becoming more and more urgent.The current simulation platform has limitations in data interaction during simulation,which is not directly oriented to the simulation system in which users participate in simulation control.Therefore,it is of great significance to design an intelligent interactive simulation system for ad hoc networking technology.In this paper,based on the research of wireless ad hoc network simulation technology,under the condition that the visualization function of the simulator is not perfect and the data service triggering methods are not enough,a simulation visualization program for ad hoc network is designed and implemented on the basis of OMNeT++ simulator and STK(Satellite/System Tool Kit).The simulation system platform for real-time display of simulation data and human-computer interaction service test requirements of ad hoc network improves the real-time and interactivity of the whole network simulation process,and provides new support for the verification of ad hoc network simulation.(1)Based on the OMNeT++ network simulation software and the INET protocol simulation framework,the interface between simulation network and control program is researched and developed,and the data information interaction is realized through socket when simulation is running.On the basis of mobile Ad Hoc network simulation,this paper studies the simulation implementation based on INET framework in OMNeT++.According to the principle of simulator,it designs and develops the network internal message and data processing functions that meet the scene requirements for business test,and realizes the information and data interaction function during simulation.(2)Develop the connection control software based on C++ MFC(Microsoft Foundation Classes)platform,complete the connection with OMNeT++simulation network and STK visualization software,and build the network simulation system platform.The connection control software controls the STK software through the STK/Connect module,and completes the real-time display of the network scene in STK by receiving the OMNeT++simulation data.At the same time,the connection control software realizes three functions,including communication data collection,node data management and business instruction distribution.It provides users with human-computer interaction interface and key integration.It can complete the control of STK and OMNeT++ simulation network through the input data,and trigger business application command messages to be sent to the simulation network for implementation.(3)The effectiveness of the proposed architecture is verified by the performance analysis of the existing simulation platform.Through the network simulation test under different scenarios,the results show that the system can achieve the expected real-time interaction function compared with the ordinary network simulation,and meet the system parameter requirements in the simulation test.
