| 摘 要： | 为了提高无线传感器网络(wireless sensor network,WSN)中与距离无关的定位算法的定位性能,通过对DV-Hop算法的分析研究,结合计算机模拟随机分布节点位置的概率统计方法,提出一种改进的DV-HOP-M算法,该算法实现了在已知3个信标节点的情况下,对整个网络节点位置进行粗略的估计。仿真结果表明:提出的算法较之原有的DV-HOP算法,提高了基于无距离WSN定位的精确度。

| Abstract: | To improve the performance of the locating algorithm which have no relation with distance in the wireless sensor network(WSN),by analyzing the DV-Hop algorithm,combining with probability statistical method which simulated random distribution node position by computer,an improved DV-Hop-M algorithm is proposed,which realized the rough estimating of whole network nodes position in knowing three beacon node.The simulation results show that,compared with the original DV-HOP algorithm,the proposed algorithm improved the accuracy of no distance locating on WSN. |
