摘要
Ad hoc网络中现有的基于预测的路由协议在路由失效之前维护路由,但该方法增加了网络中路由控制消息的数量,针对其路由开销大的特点,提出了一种基于AODV协议并结合两种路由维护方式的预测路由协议(PAODV)。PAODV中的每个节点都可能发起路由维护,根据节点在路由中的位置选择不同的路由维护方式;根据网络中节点移动特性与网络规模计算节点判决路由失效的能量阈值,确定是否发起路由维护。仿真结果表明,PAODV在保证网络可靠性的基础上降低了3~5%的网络路由开销,尤其适用于节点数目较多且移动速度较慢的网络环境。
The existing routing protocols for Ad hoc networks maintained routing using prediction method before routing became invalid,but they would easily lead to a high overhead due to broadcast lots of route message.To reduce the overhead,a routing protocol called PAODV based on on-demand routing discovering of AODV which contained two different methods of routing maintaince was proposed.Every node in a active routing would maintain its routing based on PAODV and computed the threshold which decided whether maintain the routing with the speed of noeds and network environment.Simulation results demonstrate that PAODV could reduce3~5%overhead of network and ensure the reliability of network,especially suitable for the network environment which had more number of node and slower mobility.
