Zigbee无线解决方案网络层研究

Studying of Zigbee Network Layer

文章介绍了Zigbee网络的组网过程及网络扩展的方法;首先简单介绍了Zigbee协议的网络层,接着给出了建立一个新网络的过程,及加入网络的两种方法;在这里,孩子节点可通过以下两种方式加入到网络中:通过MAC子层连接程序加入或通过先前指派的父节点直接加入网络;最后,文章针对Zigbee网络的现状及发展情况,提出了未来在无线Zigbee网络研究中需要解决的问题。

The procedure of establishing Zigbee wireless network and the ways to extend the WSN are introduced. Firstly, the network layer of Zigbee and the service access point are introduced. Secondly, the process of establishing a new network and two kinds of ways of joining a network are presented. A child can be added to a network in the following two ways ： the child can join the network using the MAC layer association procedure or the child can be added to the network directly by a previously designated parent device. Finally, the problem need to be studied in the future are brought forword.
