基于移动节点的无线传感器网络节点定位新算法
A new node localization algorithm for wireless sensor networks based on mobile anchor points
摘要
Abstract
In consideration of the low accuracy and high energy consumption of existing mobile anchor point based node localization algorithms for wireless sensor networks, this study puts forward a new node localization algorithm based on mobile anchor points.When using the algorithm, mobile anchor points move across the network in a particular model and broadcast beacon messages with position information in a certain period.Unknown sensor nodes receive the beacons within the sensing range.Then, the beacons' locating information, received signal strength and the property of particular move model are used to estimate sensor nodes' location based on geometric principles.Simulation result shows that proposed localization algorithm is efficient in improving the localization accuracy, stabilization and energy utilization compared with other localization algorithms.关键词
