| 摘 要： | 现有的定位方式因为需要建立网络模型和能量消耗不平均的现象,故不适用于有少量节点随机移动的无线传感网络.针对此类无线传感网络中各节点的定位问题,在分析了定位的计算复杂度和能量损耗的前提下,提出了分簇定位算法,在簇的范围内对发生移动的节点采用接收信号强度测距(RSSI)与质心定位相结合(CLA)的方法进行定位.分析与仿真结...

| Abstract: | The existing location method usually need to establish network model and the energy consumption is inequality.So it does not apply to a small number of mobile nodes in wireless sensor networks.Aim at the positioning of each node in such wireless sensor network,on the premise of analysing the computational complexity and the energy consumption of positioning,clustered location algorithm is proposed.Using Receiving Signal Strength Location(RSSI)combined with Centroid Localization Algorithm(CLA)to locate the mobile nodes in the cluster.The analysis and simulation results show that:the improvement of clustering method can improve the positioning accuracy and reduce the network energy consumption effectively.The network life cycle achieve the longest. |
