【摘要】： 无线传感器网络(WSN,wireless sensor network)是微机电系统、片上系统和无线通信技术高度集成而孕育出的一种新型信息获取和处理模式。在无线传感器网络的研究领域,定位问题是一个亟待解决的问题。本文针对WSN定位是否依赖测距的标准对定位的方法进行了分类讨论,在分析和总结已有定位算法的优缺点的基础上,文章提了信标节点三角形放置的混合策略定位算法,并通过在Matlab环境下建立仿真环境,对该算法进行仿真。通过对该算法与质心算法、加权质心算法在仿真模型中的结果进行对比,论证了该算法的优势。本文运用ZigBee技术实现了WSN室内定位系统。ZigBee技术具有网络结构简单、节点体积小、成本低、功耗低等特点,因此与蓝牙或802.11b等同属短距离无线通信技术相比,zigBee技术具有先天的优势。文章对WSN定位演示系统的设计步骤进行了详细的讲述,如信标节点的布置,未知节点的定位程序设计,监控中心软件设计等。经过多次反复的检测、调试,定位系统定位精度高、运行稳定,工作可靠、安全。
[Abstract]:Wireless sensor Network (Wireless sensor Network) is a new information acquisition and processing mode, which is a highly integrated MEMS, on-chip system and wireless communication technology. In the research field of wireless sensor networks, localization is an urgent problem to be solved. This paper classifies and discusses whether WSN localization depends on the standard of ranging or not. On the basis of analyzing and summarizing the advantages and disadvantages of existing localization algorithms, this paper proposes a hybrid strategy localization algorithm for beacon node triangle placement. The algorithm is simulated by establishing a simulation environment in Matlab environment. By comparing the results of the algorithm with centroid algorithm and weighted centroid algorithm in the simulation model, the advantages of the algorithm are demonstrated. In this paper, the WSN indoor positioning system .ZigBee is realized by using ZigBee technology. It has the advantages of simple network structure, small node size, low cost, low power consumption, etc. Therefore, compared with Bluetooth or 802.11b, which belong to short-range wireless communication technology, ZigBee technology has inherent advantages. In this paper, the design steps of WSN location demonstration system are described in detail, such as the layout of beacon nodes, the location program design of unknown nodes, the software design of monitoring center, etc. After repeated testing and debugging, the positioning system has high positioning accuracy, stable operation, reliable work and safety.
