Comparative Research and Simulation on Routing Protocols in Wireless Adhoc Network

该文重点介绍了移动无线自组网络中的两种典型路由协议OLSR与AODV,通过NS3模拟器模拟了在其他因素不变的情况下,节点最大移动速度、节点传输能量的变化对移动无线网络中两种路由协议性能的影响。最后通过分析得出结论:OLSR协议适用于节点移动速度低、节点传输能量低的网络;AODV协议适用于节点移动速度快、节点传输能量高的网络。

OLSR and AODV,the two typical routing protocols, are introduced in this paper. Under different simulation scenarios using NS3 simulator, the simulation results present the performance indicators of the two typical routing protocols. While changing some parameter values such as node movement speed and node transmit power, the performance indicators based on this two typical routing protocols vary obviously. Finally draw a conclusion: OLSR is applied in slow node movement speed,low node transmit power wireless network; AODV is applied in rapid node movement speed, high node transmit power wireless network.
