Wireless Monitoring Network Design
Abstract
With the quick growth of the wireless network technology, there are more and more existent network services trending to adopt wireless network technology. The popularization of IEEE 802.11 Wireless LAN and IEEE 802.16 Wireless Broadband Network, all make the wireless network technology become more and more important, futhur more, there are many relative technologies and products appeared. Following Bluetooth s rise and development, Wireless Personal Area Network (WAPN) also became popular. Therefore, one application of WPAN-Wireless Sensor Network,begins to be discussed widely.
IEEE802.15.4 is a newpromoting wireless protocol,which defines the standard for wireless low-rate personal area network.It provides the definition interface for the application layer.
Zigbee wireless sensor net work combines sensor technology,communication technology and computer technology together.It has the ability of collecting,transferring and processing data. Sensor network technology was firstly used in military systems.But now,it has been used in almost all of the fields with the development of sensor network technology.A kind of network constructed by using CMCU controller and CC2420 transceiver shows a good performance in low power comsumption and stability and is assumed well qualified to undertake some small tasks. The sensor network will be improved in the future aiming at the enhancement in data processing and communication areas.
KEY Words: ZigBee、IEEE802.15.4、CC2430、51MCU、Low-data-rate、Low-power-comsumtion、Wireeless sensor network
