| 摘 要： | 由于传感器节点能量受限,定位算法需要综合考虑定位误差、通信和计算开销等多方面的因素。分析了DV-Hop算法定位过程并总结出误差产生的主要原因,针对不同位置锚节点对定位误差的影响,提出了一种基于最优锚节点的定位算法—DV-Hop_Bon(DV-Hopbased on optimal nodes),最后使用Matlab进行了仿真实验,结果表明:新提出的定位算法在拥有较小通信半径情况下,能有效提高定位精度,并可广泛应用于无线传感器网络中。

| Abstract: | Because of restricted energy of the sensor nodes,the location error,costs of communication and computation should be considered in localization algorithms.The DV-Hop algorithm was detailedly analyzed and the main reasons for the error were pointed out,aiming at the different position anchor nodes' effect on location error,a novel localization algorithm called DV-Hop_Bon(DV-Hop based on optimal nodes) based on optimal nodes was put forward.Finally,it was simulated on Matlab,the results of the simulation show that the novel localization algorithm improves the localization precision with a short communication radius.Therefore it can be applied to wireless sensor networks widely. |
