【摘要】 无线传感器网络是一种以数据为中心的自组织无线网络。网络中的节点密集,数量巨大且部署在十分广泛的区域:网络拓扑结构动态变化,网络具有自组织和自调整的特点。网络节点具有成本低体积小,能量及其有限,计算能力、存储能力和通信能力有限的特点。国内外对无线传感器网络的研究主要集中在MAC算法、路由算法、定位算法机数据融合算法上。在协议栈各层的功能定义上、在各层数据帧格式、层与层之间的接口、每一层内的规范管理上都考虑较少。低成本、低功耗、应用简单的IEEE8 02.15.4/ZigBee协议的诞生为无线传感网络及大量基于微控制应用提供了互联互通的国际标准,也为这些应用及相关产业的发展提供了有力的契机。IEEE802.15.4/ZigBee协议是由IBEE802.15.4标准的PHY和MAC层再加上ZigBee的网络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。本文针对无线传感器网络系统中的IEEE8 02.15.4/Zigbee技术做了研究,提出并实现了一个基于IEEE8 02.15.4/Zigbee技术的无线温度传感器网络平台。设计了该系统的总体结构,包括硬件结构和软件平台。该平台使用新兴的IEEE802.15.4/Zigbee协议来作为无线传感器网络的通信协议,使得该无线传感器网络平台可组成高容错性、低能耗、低成本的多跳分布式传感器网络。论文的主要研究内容和创新如下:设计并实现高可靠性、高鲁棒性、低功耗的Zigbee网络平台,并实现在该平台上通过无线网络传输温度传感器的数据和控制信息。更多还原

【Abstract】 Wireless sensor network is a kind of self-organization wireless network which taking the data as center. The node in network is intensive, huge quantity and covering a large area, and the network topology is dynamic, and the network was self-organization and self-modulation. The node has some characteristics such as low cost, small volume, limited energy and limited computing, limited memory, limited communication. The energy of node is the most decisive factor of designing node.Now the research on wireless sensor network concentrates primarily in the protocol of MAC, routing algorithms and integration algorithms. Each layer’s function defined of the protocol stack, data frame form, the uniform interface definition between difference layers and each layer’s regular management are considered fewer. The appearance of IEEE802. 15. 4/ZigBee protocol which of low cost, low power consumption and simple application offers the international standard for wireless sensor network and application based on micro-control. At the same time it offers the chance for the applications and the development of related industries. IEEE802. 15. 4/ZigBee protocol is constituted of IEEE802.15.4’s PHY and MAC layer, ZigBee network layer and application layer. Its outstanding characteristics are the system supporting low cost operation, easily realization of the dependable data, short distance operation, the very low power consumption and the different layers safety etc.In the paper, we analyze the IEEE802.15.4/ZigBee protocol, and propose an intelligent control platform for wireless sensor network based on IEEE8 02.15.4/Zigbee protocol. We use the IEEE8 02.15.4/Zigbee protocol as the wireless network protocol of the sensor network, which can make the structure of network more flexible and robust.The paper includes the following research: develop and relize a reliable, robust and low power dissipation Zigbee system; on the system, data and control information of temperature sensor can be transmitted by wireless communication.更多还原
