多路径DSR和AODV路由协议性能研究:在支持移动节点和自组织网络的路由协议中,最典型的单径路由协议是DSR 和AODV 协议,对它们进行扩展分别得到相应的多径路由协议。通过仿真比较分析这2 种多径路由协议在混合无线Mesh 网络和移动Ad Hoc 网络中的性能。结果显示,混合无线Mesh 网络中的这2 种多径路由协议具有分组传输率高、端到端的平均延时和路由开销小等优点。以DSR 协议为基础扩展得到的多径路由协议,在高度动态的网络环境中,性能得到了改善,能广泛应用于移动性强的环境中。关键词:动态源路由协议;Ad Hoc 按需距离矢量路由协议;混合无线Mesh 网络;移动Ad Hoc 网络;多径路由协议【Abstract】Dynamic Source Routing(DSR) and Ad Hoc On-demand Distance Vector routing(AODV) protocols are most typical single-path routingprotocols, which support mobile node, self-organization and self-configuration network. The multi-path variants of DSR and AODV are extension ofDSR and AODV. This paper compares performance of multi-path variants in hybrid wireless Mesh networks and mobile Ad Hoc networks bysimulation. Result shows that, multi-path variants based on hybrid wireless Mesh networks have such feature as more higher packet delivery ratio,more lower end-to-end average latency and routing overhead. The multi-path version of DSR can be applied to highly mobility environment due toprominent improvement of performance under dynamic network environment.【Key words】Dynamic Source Routing(DSR) protocol; Ad Hoc On-demand Distance Vector routing(AODV) protocol; hybrid wireless Meshnetworks; mobile Ad Hoc networks; multi-path routing protocol
