低功耗ZIGBEE无线传感器网络通信研究
摘要
随着无线网络技术的快速发展和传感器技术的日益成熟,无线传感器网络应运而生。无线传感器网络就是由部署在监测区域内大量的廉价微型传感器节点组成,通过无线通信方式形成的一个多跳的自组织的网络系统,其目的是协作地感知、采集和处理网络覆盖区域中感知对象的信息,发送给观察者。近年来,无线传感器网络被广泛的应用在预防医学、环境监测、森林灭火乃至车辆检测、行星探测等领域,成为国内外广泛讨论的焦点。
(low-rate wireless personal work,LR-WPAN),把低能量消耗、低速率传输、低成本作为重点目标,可为个人或者家庭范围内不同设备之间低速互连提供统一的标准。.4标准的PHY和MAC层再加上ZigBee的网络层和应用支持层所组成的,其突出的特点是网络系统支持极低成本、易实现、可靠的数据传输、短距离操作、极低功耗、各层次的安全性等。
本文首先详细介绍了ZigBee技术产生的背景、特点以及优势,经过分析比较几种典型的网络拓扑结构,采取星型网的组网方式,构建了ZigBee协议硬件开发平台,软件实现了Zigbee协议栈和节点间的通信。
本课题采用C8051F单片机作为网络终端节点和网络协调器的MCU,2430为射频芯片,搭建了一个基于Zigbee的无线传感器网络。2430芯片进行通信。在系统软件设计方而,利用现有协议、相关函数和源代码,进行了相关网络模拟通信。最后对论文进行了总结,并在现有基础上对今后的扩展与开发进行了展望。

Low-power Wireless munication of Zigbee
Abstract
With the rapid growth of the work technology and increasing ripe
sensor technology, Wireless es. Wireless work(WSN)is
made up of a great deal of low-cost subminiature sensor nodes, which are set in the
monitoring area. It can make a many work by the munications by purpose is to apperceiving, collecting and processing the objects which are in work system, and sending the information to the observer. Recently years,
Wireless work has been applied in various fields such as preventive medical, monitoring environment,putting out forest fire,researching benthonic boards,exploring , is ing the hot topic in domestic and abroad.
The standard for the low-rate wireless personal work (LR-WPAN) takes up with low wastage,low rate and low cost for purpose,And it can supply a uniform standard for personal different facilities in family protocol is constituted of 's PHY layer and MAC layer,work layer and application support outstanding characteristic is that the system support low cost operation,easy realization of the dependable data,short-distance opera
