| 摘 要： | 提出一种分布式节点定位算法:移动锚节点辅助多坐标系定位算法(MBA-MC),用于无线传感器网络节点定位.移动锚节点在WSN节点分布区域内移动,同时周期性发送信标信号,并且在同一位置分别在多个不同的发射功率下发送信标信号.未知位置节点接收信标后估算与锚节点距离范围,然后利用在多坐标系系统下接收的信标信息得到多个扇形的交叠区,并认为交叠区中心就是节点自身位置.仿真结果表明:在相同条件下,本文提出算法比其他算法能取得更好的定位准确性,其全分布式计算定位方式特别适用于大规模的无线传感器网络节点定位.

| Abstract: | A distributed localization algorithm in wireless sensor networks,that is,a mobile beacon assisted multi-coordinate(MBA-MC) localization algorithm,is proposed.The mobile anchor traverses across the whole WSN field and periodically broadcasts the beacons at two or more different power levels(including its current information).Each unknown node in the field passively receives the beacons within its sensing range,by using the information received from each beacon in the multi-coordinate systems;each node can ob... |
