【摘要】 微机电系统(MEMS, Micro-Electro-Mechanism System)、片上系统(SOC,System on Chip)和无线通信技术的发展孕育了无线电传感器网络(WSN, Wireless Sensor Network)。这种网络系统可被广泛地应用于环境监测、医疗卫生、交通管理、制造业、国防军事、反恐抗灾等领域。作为一个全新的研究领域,WSN向科研工作者提出了大量的具有挑战性的研究课题,传感器网络的定位问题及其在军事上的应用就是其中非常重要的两个方面。本论文的研究工作是围绕着无线电传感器网络定位算法及其在军事领域的应用进行的,主要完成的工作包括:1.介绍了无线电传感器网络的特点、体系结构,将无线电传感器网络和其他网络进行对比,分析了目前无线电传感器网络研究所面临的问题,并针对其定位问题进行阐述。2.综述了无线电传感器网络定位算法的分类方法,以及现有的典型算法,并对现有的成果进行总结。3.阐述无线电传感器网络在军事应用领域所独有的技术优势,并对其在军事上的主要应用方向进行了描述。结合自身参与的国防工程项目,概述了基地电磁辐射源定位和监测系统,详细描述了系统定位过程和定位算法的实现。更多还原

【Abstract】 Advances in MEMS(Micro-Electro-Mechanism System)、SOC(System on Chip)and Wireless Communications have made WSN(Wireless Sensor Network)possible, here each sensor node individually senses the environment but collaboratively chieves complex information gathering and dissemination tasksInstrumenting the physical world through large networks of wireless sensor nodes requires that these nodes be very small, lightweight, untethered, and unobtrusive. These networked sensor nodes, however, possess several characteristics that have challenged many aspects of traditional computer network design. The problem of self-localization, that is, determinin where a given node is physically or relatively located in a network, is one of the challenging tasks.and yet extremely crucial for many applications.The research of this thesis is based on the research results of the Wireless Sensor Network Self-Localization algorithm and its application in military include:1. This paper gives an instruction about the architecture and characteristic of wireless sensor network. Contrast the wireless sensor network with other networks. Analysis the problem about what the reseach of the wireless sensor network is facing.2. The taxonomy for wireless sensor networks localization system and algorithms are described, the principles and characteristics of recent representative localization approaches are discussed andpresented in detail.3. The preponderances of the wireless sensor network when used in military are described,and the use of the wireless sensor network in military is summarized。Combine the national defense engineering of oneself participation item, all said base electromagnetism to radiate source fixed position and monitor system, described the realization of the system fixed position process and fixed position calculate way in detail.更多还原
