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。
In order to study the performance of different wireless ad hoc networks routing protocols in Mesh topology networks, ZigBee routing, Dynamic Source Routing Protocol (DSR) and Plane Distance Vector Routing Protocol (AODV) are selectively used in network design. Three wireless ad hoc network routing protocol ideas and principles. Through the network simulation software NS-2, under the same conditions of other external conditions, the three are simulated in the Mesh topology network, and the line chart of three performance indicators of end-to-end average delay, packet transmission rate and routing overhead rate is obtained. From the simulation results, ZigBee routing has unique advantages in its application range and is suitable for application in Mesh topology networks.
