| Abstract: | The key factor of current agent system,which affects the performance of mobile agent-based satellite network routing algorithm,is investigated through simulation.The routing algorithm simulated is given,and its simulation method in NS2 is presented.Agent system-based Satellite Network Simulation platform（ASNS）is elaborated.ASNS operating in local area network is constructed based on Linux,Grasshopper and JADE.Several essentials are presented,including simulation platform architecture,satellite entity,routing agent interaction interface and inter-satellite link simulation module.Through analyzing the simulation results from NS2 and ASNS,such conclusion is drawn that mobile agent migration efficiency under high link delay is the decisive factor on the performance of mobile agent-based satellite network routing algorithm.Besides,based on the comparison between agent systems,the choice strategy of agent system is suggested to develop routing algorithm and its simulation platform. |
