ZigBee Wireless Control System Campatible With EIB

Wireless personal area network (WPAN) technology is starting to take off in market and shows a great potential. There are many arising WPAN standards, in which ZigBee technology attracts the focus of industry for its characteristics of low cost, low power, short coverage and self-maintance.This paper compares several popular WPAN standards including IrDA, Bluetooth and UWB with ZigBee and does a deep research on ZigBee technology. Based on these work, a new scheme, which is aimed to solve the problems of EIB wireless communication, is proposed by using ZigBee technology in EIB system. And finally, some advices to improve the performance of routing algorithm are put forward.The paper is divided into five chapters.The first chapter introduces the history of ZigBee and gives a comparison among several WPAN technologies. And then the paper predicts the future and developing trends of ZigBee technology.The detailed analysis about ZigBee protocol is given in the second chapter. This part describes the application layer, network layer and security services provider breifly.The third chapter analyzes the differences between EIB and ZigBee, and proposes a ZigBee wireless control system compatible with EIB system. And an application example in wireless lighting control system is designed to improve its feasibility and practicability.In the forth chapter the routing algorithom is researched including its strengths and weakness. And then some revisions are proposed to improve its performance by dealing with the Busy Nodes and the discovery of routing lost, which is also used in wireless lighting control system.In the last chapter, all the work is summarized and a plan for the future R&D is given.
