基于相关因子的节点不相交的Ad Hoc多路径路由算法

多路径路由算法可以均衡负载、提高可靠性，但是Ad Hoc网络的无线多播特性（WMA）使得多路径数据传输存在严重的；中突隐患，即便是节点不相交的多路径，以并发的方式来进行数据传输的效率并没有理论上的高．为此本文提出基于相关因子的节点不相交的多路径路由算法（NDCF），该算法引入相关因子来衡量多条节点不相交路径以并发的方式进行数据传输时发生；中突的可能性的大小，从而选择冲突可能性最小的节点不相交路径．仿真结果表明，NDCF算法可明显提高数据包的投递率．降低端到端的传输时延．

Node-Disjoint Multipath Routing Based on Correlation Factor in Ad Hoc Networks

Multipath routing algorithm can balance network load and enhance reliability.However,due to the wireless multicast advantage(WMA),there exists serious collision.Therefore data transfer rate of most multipath routing,even if node-disjoint,is not so high as our anticipation.In order to solve the problem,this paper proposes a Node-Disjoint multipath routing based on Correlation Factor(NDCF) algorithm for Ad Hoc networks.This algorithm introduces correlation factor to weigh the collision probability between node-disjoint multipath when transmitting data simultaneously,then chooses the node-disjoint multipath which collision probability is minimum.Simulation results show that NDCF algorithm can obviously improve packet delivery ratio and reduce end to end delay.
