2、遲，避免了沖突。針對(duì)AODV算法高控制開(kāi)銷(xiāo)的不足，提出了基于最快路徑的AODVjr算法，通過(guò)簡(jiǎn)化路由發(fā)現(xiàn)和路由表、刪除Hello消息以達(dá)到降低控制開(kāi)銷(xiāo)的目的。為了更進(jìn)一步達(dá)到低控制開(kāi)銷(xiāo)的目的，本文提出AODVjr算法和Cluster-Tree算法相結(jié)合的ZBR路由算法，該算法既具有AODVjr的路由尋優(yōu)的能力，又具有Cluster．Tree算法的無(wú)初始延遲的優(yōu)點(diǎn)。通過(guò)仿真表明，改進(jìn)的算法能夠較好的達(dá)到設(shè)計(jì)要求，具備了實(shí)現(xiàn)的可行性。本文最后利用改進(jìn)的組網(wǎng)方案和ZBR路由算法，首先利用NS2軟件對(duì)一個(gè)完整
