ZigBee网络中不同路由性能的研究与仿真

摘要

ZigBee是一种近距离、低复杂度、低功耗、低数据速率、低成本的无线通信技术，广泛用于物联网，自动控制和监视等诸多领域。文章首先介绍ZigBee网络的技术特点，然后利用OPNET仿真软件研究比较了网状路由和树状路由性能，并得出网状路由比树状路由具有更小的跳数、更低的延时和更低的MAC负载。%　　ZigBee is a close, low complexity, low power consumption, low data rate, low cost wireless communication technology, widely used in the Internet of Things , automatic control and monitoring, and many other fields. This paper firstly introduces ZigBee network technical characteristics, and then research and compare the performance of tree based routing and mesh routing in a ZigBee network with the OPNET, and obtain the mesh routing has smaller number of hops, lower global end-to-end Delay and lower global MAC Load per PAN than tree routing.
