卫星中断容忍网络路由算法研究
Research on Routing Algorithm of Satellite Delay-Tolerant Network
摘要
Abstract
For the problems of interrupt、long delay in Satellite network,which proposes a routing algorithm which is suitable for Satellite DTN network--SDTNR algorithm is proposed. This algorithm set up three queues,each queue stores the packet of different service levels and sorts according to the ration of packet’s response,and meanwhile,this algorithm sends the packet whose ration of response is small preferentially. SDTNR algorithm based on the predictability of satellite set up node selection table and updated the table in real time,according to the information in the table to select several nodes which meet the conditions as the next hop node,in order to ensure the reliability of communication. The simulation results show that,SDTNR compared with EPR,PR,FC,which can greatly improve the packet delivery ratio,and reduces the network overhead and average delay.关键词
