一种节点独立的MANET网络多径路由协议

A Node Disjoint Multipath Routing Protocol in Mobile Ad Hoc Networks

论文提出了一种基于AODV(adhocon-demanddistancevector)的节点独立多径路由协议NDM(NodeDisjointMultipath),NDM在路由发现过程中记录每跳信息,这样一方面能够发现节点独立的多径路由,别一方面也很简单地解决了路由环路的问题。论文还从理论上探讨了多径路由个数的问题,通过仿真表明NDM在节点移动速度较高时数据包投送率、端端平均时延、路由发现频率等方面都明显优于标准的AODV协议。

This paper proposes a node disjoint multipath routing protocol NDM(Node Disjoint Multipath),which is based on AODV(ad hoc on-demand distance vector).In NDM the information of every hop is recorded during the route discovery phase,which can not only discover the node disjoint path,but also solve the problem of loop-free path simply.It also studies the number of multipath in theory,the simulation shows that when nodes move at higher speed the performance of NDM is obvious better than AODV in the ways of packet delivery fraction,average end-to-end delay and route discovery frequency.
