摘要/Abstract

摘要： 首先分析了DSR路由协议，然后提出了一种简单易实现的独立多径路由算法.该算法中只有目的节点应答路由请求，中间节点只转发一次路由请求，这样不仅减少了路由分组的数量，而且能为目的节点尽可能提供多条独立路径，减少了目的节点路由计算的复杂度.在NS2环境下与DSR路由协议在路由开销、丢包率和端到端的平均延时方面进行了对比实验，实验结果表明SIMR算法的性能优于DSR路由协议.

Abstract: The DSR protocol is first analyzed. Then, a simple independent multipath routing protocol is proposed based on DSR. Only the destination nodes respond to the routing request, and the middle nodes could only pass on the routing request once. In doing so, it not only reduces the number of routing packets but also provides independent routes for as many destination nodes as possible. The DSR protocol is compared with the SIMR algorithm under NS2 in overhead routing, packets loss rate and average endtoend delay. The results show that the performance of the SIMR algorithm is better than the DSR routing protocol.

Key words: Ad hoc, DSR, independent multipath , routing protocol
