一种基于RREP的最大生存期改进AODV路由协议

ODV routing protocol is widely used in wireless mesh network (WMN).To cope with the problem of traditional AODV can not predict the lifetime of routing effectively, this paper proposes an improved AODV based on maximum lifetime (LAODV), using reply messages to send back routing lifetime to broadcast node, select a routing path with relatively long lifetime, avoiding the routing performance decrease along with the routing interruption caused by the mobile nodes move frequently. Simulation analysis shows that LAODV could establish a better routing than the traditional AODV to a certain extent.
