Abstract: In Ad hoc networks，multipath routing is better suited in the stability and load balance than single path for its mobility and topology variability．Whereas the limitation of energy in Ad hoc network ，a new multipath routing scheme which is based on DSR is proposed .The scheme utilizes the power drain rate and predicts the lifetime of link, finds some effective paths and sends data through these paths.The simulation result shows that the protocol is superior to DSR in throughput and end to end delay．

摘要： 在移动自组网中，由于网络节点的移动性的拓扑结构的多态性，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进行传输。仿真试验表明，该协议比DSR具有良好的吞吐量和端到端延迟。
