摘　　要：在移动自组网中,由于网络节点的移动性和拓扑结构的多态性,多路径路由在稳定性,均衡负载方面优于单路径路由,非常适合Ad hoc网络。考虑到移动自组网中节点能量的局限性,在DSR协议的基础上提出了一种新型的多径路由算法。该算法结合节点路径的能量消耗率,预测出链路的生命期,以求找到多条有效路径并进行传输。仿真结果表明,该协议比DSR具有更好的吞吐量和端到端延迟。In mobile Ad hoe networks,multipath routing is better than single path in the stability and load balance for its mobility and topology variability.Considering the limitation of energy in ad hoc network,we will propose a new multipath routing scheme,which based on DSR.The scheme utilizes the power drain rate and predicts the lifetime of paths,and Sends data through these effective paths.The result of simulation shows that the throughput and end to end delay of the protocol is superior to DSR.
