摘要无线传感器网络(WSN)综合了微机电技术、传感器技术、嵌入式计算技术、分布式信息处理技术和无线通信技术，能够实时监测、感知和采集各种环境或监测对象的信息并对其进行处理，并将信息传送到用户。而在传感器网络中，位置信息对传感器网络的监测活动至关重要。因此，确定事件发生的位置或获取信息的节点位置，即定位技术是无线传感器网络中的关键技术，是无线传感器网络进行目标识别、监控、跟踪等众多应用的前提。
本毕业论文在查阅大量相关文献的基础上，介绍了无线传感器网络的基本概念，对无线传感器网络定位技术做了整体概述，并综述了无线传感器网络定位算法的原理、评价标准和分类方法。其中，详细列举了几种常用的定位算法，如基于测距的定位算法以及DV-Hop等非基于测距的定位算法，并且运用C++语言编程来仿真基于测距的定位算法的定位过程和定位结果。
在此基础上，综合考虑各种环境因素、人为因素如室内温度、信标节点布置均匀与否等，运用C++语言编程，建立通用的定位仿真模型。借助该通用模型，我们可以较好地解决室内的定位问题，并且得到在规定误差范围内的定位结果。10920

Title: The Simulation Research Of The Positioning Algorithm Of The Wireless Networks.
Abstract
Wireless sensor networks (WSN),which integrate the technologies of the Micro-Electro-Mechanical System (MEMS),sensor technology, embedded computing, distributed information processing and wireless communication, can test, sense, collect, process and transfer the information of monitored objects to terminal users in real time. As the location information is vital to the testing in wireless sensor networks, determining the location of the incident and obtaining the node position, namely the positioning technique, is one of the key techniques in the wireless sensor networks, which is the prerequisite of the target identification, surveillance , tracking and many other applications of the wireless sensor networks.
     Based on large amounts of literature, the thesis first of all introduces the basic concept of the wireless sensor networks and the outline of the positioning technique, then summarizes the principle, evaluation standards and classifications of the positioning algorithm. A few examples are given such as the range-based algorithm and the range-free algorithm like DV-Hop. Then C++ programming language is used to simulate the positioning process and results of the range-based algorithm.
      Considering all the environmental factors and human factors like the room temperature and the beacon nodes arranged uniformly or not, the C++ programming language is used to establish the general simulation model of positioning. And the problem of indoor positioning can be solved properly with this general model, obtaining the location results within the error.
