| 摘 要： | 本文针对无线ad hoc网络提出了一种基于DSR(动态源路由)的路由算法,多径源路由(MSR).MSR对DSR中的路由搜索和路由维护机制进行了扩展,用来解决多径路由问题.本文还提出,在多条路径之间基于测量的RTT进行负载分配.仿真结果表明,MSR在只增加少量网络开销的情况下,提高了TCP和UDP的投递率,降低了丢包率,并减少了端到端之间的延迟以及队列长度,从而有效地减少了网络拥塞.

| Abstract: | In this paper,we propose a new multipath routing protocol for ad hoc wireless networks-Multipath Source Routing (MSR),which is based on DSR (Dynamic Source Routing).MSR extends DSR's Route Discovery and Route Maintenance mechanism to deal with multipath routing.Based on the measurement of RTT,we propose a scheme to distribute load between multiple paths.The simulation results show that our approach improves the packet delivery ratio of TCP and UDP,and reduces the end-to-end delay,packet loss rate and the queue size,while adding little overhead.As a result,MSR releases the network congestion quite well. |
