多路徑DSR和AODV路由協議性能研究:在支持移動節點和自組織網絡的路由協議中，最典型的單徑路由協議是DSR 和AODV 協議，對它們進行擴展分別得到相應的多
徑路由協議。通過仿真比較分析這2 種多徑路由協議在混合無線Mesh 網絡和移動Ad Hoc 網絡中的性能。結果顯示，混合無線Mesh 網絡
中的這2 種多徑路由協議具有分組傳輸率高、端到端的平均延時和路由開銷小等優點。以DSR 協議為基礎擴展得到的多徑路由協議，在
高度動態的網絡環境中，性能得到了改善，能廣泛應用于移動性強的環境中。

【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.
