摘要
为了研究在Mesh拓扑网络下不同无线自组网络路由协议的性能优劣,在网络设计中有选择地使用,分析和研究了ZigBee路由、动态源路由协议(DSR)和平面距离矢量路由协议(AODV)三种无线自组网络路由协议的思想和原理。通过网络模拟软件NS-2,在其他外部条件相同的条件下对三者在Mesh拓扑结构组网进行模拟,得到端到端平均延迟、包传输率和路由开销率三种性能指标的折线图。从仿真结果图上看,ZigBee路由在其应用范围内具有独特优势,适合在Mesh拓扑网络中应用。
For studying the advantage and disadvantage of different Ad Hoc routing protocols in Mesh topology,and thus for optional application in network design,the concepts and principles of three wireless Ad Hoc network routing protocols—AODV,DSR and ZigBee routing protocols are analyzed and studied.Then,with NS-2 simulation software,these three protocols in Mesh-topology network are simulated under the same other external conditions,and thus the three broken line graphs indicating the average end-to-end delay,packet transmission rate and routing overhead are obtained.In the graphs one can see that the ZigBee routing protocol has unique superiority in its application area and is suitable for application in this topological structure.
