基于OPNET的Zigbee拓扑性能仿真研究

Topological performance of Zigbee and simulations on OPNET

为了有效的配置家庭自动化系统中的IEEE802.15.4/Zigbee网络,使用OPNET软件仿真Zigbee标准中定义的三种网络拓扑结构,分析在相同的参数下各拓扑结构对网络吞吐量,时延等性能的影响,仿真结果表明星形结构时延最大,吞吐量最小而网状网时延最小,簇状网的吞吐量最大。

In order to make the IEEE802. 15.4/Zigbee network understood well and collocated effectively, its three topological structures, the star, the mesh, and the cluster, are introduced. Based on OPNET, and given the same parameters, simulations are done to find how the throughput and delay of a network are affected by the structure. Simulation results show that, the star is of maximum delay and minimum throughput, the mesh is of minimum delay, and the cluster is of maximum throughput.
