| 摘 要： | 为了提高容迟(DTN)的传输效率,同时减小网络延迟和网络开销,借鉴链路状态算法,使用Dijkstra计算路由,并充分考虑了传输延迟、节点之间的连接性和历史因素,提出了一种基于概率延迟的DTN路由算法PD.模拟实验结果表明,PD在传输延迟较大的网络环境下,性能优于其它同类算法.

| Abstract: | In order to improve the transfer efficiency while at the same time reduce the network delay and network cost in delay tolerant network(DTN),a DTN routing algorithm based on probabilistic delay,namely PD,is proposed.The link state algorithm is referenced in PD.Transfer delay,connectivity between nodes and historical factors are fully taken into consideration.Through simulative analysis,PD is found to be able to achieve better performance than CAR and epidemic routing in network environment with relatively long network transfer delay. |
