摘 要: 对按需距离矢量(Ad Hoc on-demand distance vector, AODV)路由协议进行研究,提出一种基于概率转发的机制。这种机制根据邻居节点的个数,选用不同的概率转发路由请求报文(Route REQuest, RREQ)。NS2仿真模拟表明:该方法可以降低时延,提高吞吐量,提高分组投递率。
关 键 词: 计算机网络;无线网络;AODV;概率转发;NS2;广播风暴

Abstract: This paper researched Ad Hoc on-demand distance vector (AODV) routing protocol and gived a mechanism based on probabilistic forward.This mechanism chose different probabilistic forwarding Route REQuest (RREQ) through neighbor's numbers.The NS2 simulation results show that this idea can decrease delay and increase thoughput as well as packet delivery fraction ratio.
Key words: computer network; wireless network; Ad Hoc on-demand distance vector; probabilistic forwarding; NS2; broadcast storm
