摘要 定位技术是无线传感器网络的支撑技术之一.针对无线传感器网络低成本、低能耗的要求,在继承DV-Hop定位算法优点的基础上,提出根据跳数来调节节点定位过程中的数据包接收量即LDV-Hop定位算法.算法在局部范围内索取定位信息,并可以部分抵制MAC层冲突带来的错误信息.利用网络仿真工具Ns-2对算法进行仿真分析和比较,结果表明LDV-Hop定位算法有更高的定位精度,能有效降低数据通信量,并且对于不规则形状的节点分布具有较强的适应性. Localization is one of the supporting technologies in wireless sensor networks. A novel LDV-Hop algorithm is put forward based on the DV-Hop so as to the characters of low cost and low power in WSNs. It can adjust the quantity of communication packets according to the hops in the course of localization. Only local location information is obtained in LDV-Hop and it can also help to resist error information caused by collision in MAC layer. Simulations are made by the network simulator Ns-2. The result is that the LDV-Hop algorithm is useful to improve the accuracy of localization and reduce the number of communication messages. The algorithm is also adaptive to irregular distribution of sensor nodes.
