MDYMO：一种新的Ad Hoc按需多路径路由协议

MDYMO:New on-demand multipath routing protocol for Ad Hoc Networks

移动Ad Hoc网络(MANETs)是一种资源受限、拓扑结构不断动态变化的网络。很多Ad Hoc路由协议的研究都是集中在如何建立一条源节点到目的节点的单路径路由上,但是,使用多路径路由能够显著提高网络性能。基于DYMO协议进行了适当修改,提出了一种新的多路径路由协议——MDYMO。通过在NS-2下进行仿真测试,表明多路径不仅可以减少时延,而且能够降低网络中路由报文的传输数量。

Mobile Ad Hoc Networks（MANETs） are networks with dynamic topology and limited resources,where many routing algorithms focus on the establishment of a single path between the source and the destination.However,multiple routes have been proved beneficial.We propose a new algorithm which is based on the Dynamic Manet On-demand （DYMO） routing protocol and evaluate its performance under NS-2.Simulation results show that multiple paths can not only reduce the delay,but also decrease the transmitted routine nackets.
