The Research on Zigbee Problems of Application with a mass of Nodes
YAO Chun (School of Electronic and Information Engineering Tongji University, Shanghai 200092, China) Abstract: This paper analyzes and researches Zigbee problems of application with a mass of nodes and special requirement on node deployment. Firstly, the paper introduces Zigbee stack, node type and topology type, which provide the necessary basic theory for this kind of application. Then it researches deeply into the Zigbee network from the views of address allocation and the parameters setup which are related to network extent. It elaborates Cskip used by Zigbee address allocation and calculates the total nodes of Zigbee with different network parameters. Finally, it gives out a solution about node deployment in the application with large number of nodes.
