Abstract: Dynamic Source Routing(DSR) and Ad Hoc On-demand Distance Vector routing(AODV) protocols are most typical single-path routing protocols, which support mobile node, self-organization and self-configuration network. The multi-path variants of DSR and AODV are extension of DSR and AODV. This paper compares performance of multi-path variants in hybrid wireless Mesh networks and mobile Ad Hoc networks by simulation. 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 to prominent 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 Mesh networks, mobile Ad Hoc networks, multi-path routing protocol

摘要： 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。
