Improved routing protocol based on separation time in delay tolerant networks
DTN中一种基于分离时间的改进路由算法*

This paper proposed a new routing protocol in DTN, named epidemic routing based on separation time with forwarding tokens constrained (EPI-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.
