Research and Design of Localization Algorithm in Wireless Sensor Networks

Abstract

无线传感器网络是由多个带有传感器模块、微处理模块及无线收发模块的节点根据数据采集任务的需求自组织而成的。网络中的传感器节点通过相互协作来监控、采集和处理网络覆盖范围内感知对象的信息,并传递给无线传感器网络的用户进行进一步的扩展应用。由于具有易扩展、自组织、分布式结构和实时性等特点,无线传感器网络被广泛的应用于国防军事、国家安全、环境检测、交通管理、医疗卫生、反恐抗灾等领域。这些应用中的绝大部分都需要监测和检测传感器节点所在网络范围内的各种数据信息,尤其是节点本身的位置信息。 本文利用课题组自主研发的传感器节点SCIN(Supervisory&ControllingIntelligen...Wireless Sensor Network (WSN) consists of large numbers of cooperating small-scale disposable low-powered nodes. These nodes can supervise, collect and disposal all information in their communication range and then send results to net user. Now, WSN is wildly used in national defence, circumstance inspecting, traffic control etc. Most of these applications are based on position information of node...学位:工学硕士院系专业:信息科学与技术学院通信工程系_通信与信息系统学号:2005130240
