| 摘 要： | 针对无线传感器网络(wireless sensor network,WSN)系统中节点的定位算法问题,提出了基于差分的DV-Hop定位算法,信标节点将测算的位置测定误差作为校正值向四周区域广播,未知节点接收到信标节点的校正信息后,据此修正自身的相对位置测算值,以减少节点定位误差,提高定位算法的精度。仿真测试表明,该算法与普通的DV-Hop算法相比,在定位误差与通信距离的比值等性能指标上得到了明显改善。

| Abstract: | A DV-Hop localization algorithm from the basis of difference is proposed, which is specific to questions of node localization algorithm in a wireless sensor network (WSN) system. The beacon node surveyed the positioning error and took the correct value of the regional broadcast. After the unknown node received the adjustment information from the beacon node, it revised its own relative position reckoning value to reduce the node position error and to enhance the precision of the localization algorithm. Simulation tests show that, compared with the ordinary DV-Hop algorithm, this algorithm gets distinct improvement from performance indices between the position error and communication distance ratio. |
