ABSTRACT
In recent years, along with the social informatization, family intelligent and industrial automation etc for wireless data transmission and the increasing demand, the ZigBee agreement based on the wireless network IEEE 802.15.4 standard as a new standard of wireless sensor network technology came into being, and showed the rapid development of the good momentum, widely applied to military unattended and smart communication network, industrial automatic control, large and medium-sized cities, the air quality monitoring surveillance, highway hospital medical residents, automatic capture expends associated automatic, consumer electronics equipment of wireless connection, etc.
ZigBee technical standards based on IEEE802.15.4 low speed wireless LAN, and personal support media access control and phy standards, and on top of this include network layer, security layer and application layer. Because ZigBee technology has characteristics such as low power consumption, low latency, longer battery life and so on, it plays an extremely important role in low rate of wireless sensor network. In 2006, ZigBee industrial market, its market value reached to hundreds of millions of very broad prospects. At present, many big companies abroad have introduced to users ZigBee application solutions.
There are many universities and research institutes in the field of research, the research content covers the design of wireless sensor node hardware, operating system, network routing technology, energy-saving technology, control technology, etc, but also no one enterprise and research organizations with independent intellectual copyright ZigBee protocol stack and hardware modules, mostly based on foreign RF chip and protocol stack for application development.
This topic in the study of foreign material, or IEEE802.15.4 standards and ZigBee agreement on the basis of the standard, use the ZigBee CC2430 chip based on TI and the development kit that the chengdu wireless dragon company provided to study Z-Stack protocol stack 2006.
