无线自组织网络按需路由协议研究
Research on On-demand Routing of Wireless Ad Hoc Networks
摘要
Abstract
Routing protocols are the foundation and key link of wireless ad hoc networks.Because the wireless ad hoc networks has complicated topology changes and different routing protocols have their advantages and disadvantages,the selection of wireless ad hoc networks routing protocol has always been one of the most written topics. This article simulates AODV and DSR routing protocols with NS2 under different conditions including different number of nodes and node mobility speed in order to evaluate the delay of transport layer,the route convergence time, the number of received packets, the routing cost and the ratio of packets received etc. Simulation results show that if the number of nodes is not more than 20 and the speed of nodes is not more than 100 km/h,the overall performance of AODV routing protocol is better than DSR routing protocol.关键词
