无线传感器网络节点近点加权质心定位方法
Closer nodes weighted centroid localization for wireless sensor networks
摘要
Abstract
Node localization is the basis for Wireless Sensor Networks(WSNs) application. Centroid localization and RSSI-based cen-troid are two favorite approaches so far. However, the localization accuracy is low for the former approach; the latter is sensitive to interference factors, e. G. The signal decay exponent. The closest nodes' location is used to correct other beacon nodes' signal. Based on this, an improved centroid weighted localization method is proposed, which is further enhanced by modifying the weights for the closest node, second closest node and the sum of all nodes. Simulation results are included to demonstrate the effectiveness of the presented approach.关键词
