DTN中一种基于分离时间的改进路由算法

摘要

This paper proposed a new routing protocol in DTN, named epidemic routing based on separation time with forwarding tokens constrained (EP1-T).EPI-T selected a route according to the idea of epidemic routing and history information,which could restrict flooding range and saved the network resources.The simulation and analytical results show that EPI-T improves delivery ratio and shortens the message delivery delay.%提出一种DTN中基于分离时间的副本受限的路由协议--EPI-T.EPI-T基于传染路由思想,根据历史路由信息进行路由选择,限制信息的洪泛范围,节约了网络资源.仿真分析结果表明,新协议提高了交付率和降低了时延.
