摘要
AODV路由协议是当前移动AdHoc网络的主流路由协议,通过分析它的特征提出一种利用节点缓存的方法来限制路由请求发送范围,从而减少路由负载,提高协议效率。通过OPNET仿真表明,该方法能有效减少路由负载并对端到端时延、平均投递率等性能参数也有显著提高。
AODV is a main routing protocol of Mobile Ad Hoc network. By analyzing its characteristics, this paper proposes a new method for constraining route request broadcast based on node cashing. An extensive simulation study of AODV with node cashing in OPNET shows that the routing overhead is dramatically reduced and the other two metrics-delay and delivery ratio are significantly improved.
