摘要:
质心算法是一种简单易实现的节点定位方法，但是它的定位精度多依赖于网络中信标节点的密度和分布。针对质心算法这一缺陷，文中提出了一种移动信标节点辅助的加权质心定位算法( MBAWCL)。该算法采用一个飞行的移动信标节点在网络部署区域上空按照设定的路径移动并且周期性地广播自己的位置信息；未知节点对所接收信标信号采取一定的筛选机制存储信标信号，然后利用加权质心( WCL)方法计算自己的位置。实验测试证明该算法可以提高节点的定位精度，降低定位成本，提高定位效率
Abstract:
The centroid algorithm is a simple method to achieve node localization,but its localization accuracy depends on the density and distribution of the beacon nodes in network. According to the defect of centroid algorithm,present a Mobile Beacon Assisted Weight Cen-troid Localization algorithm ( MBAWCL) . The algorithm adopts a flight mobile beacon node to move over the network deployment area according to destined path and broadcast periodically the messages with its own localization. Unknown node takes a screening mechanism to store the received beacon signal,and then use the method of WCL to calculate its own position according to its stored beacon signal in-formation. The experiments prove that the algorithm can reduce the localization error and cost and improve the efficiency of localization
