基于ZigBee协议栈的无线传感器网络性能分析

hese sensor nodes can automatically organize themselves to form a multi-hop ZigBee-based WSN with a coordinator, several routers and a number of End-Devices. The paper analysis of wireless sensor networks will be measured by active and passive measurement. The main performance index of the networks contains of latency, packet loss rate, signal attenuation. In this work, three cases were considered and investigated, one is the distance between the End-Devices and the coordinator increases, and the second is to increase the routing hops, the third is to increase the obstacles between the End-Devices and the coordinator .The results of the analysis will help us to construct a reasonable network topology, and to construct excellent performance networks
