基于网格扫描的无线传感器网络定位算法
Wireless Sensor Network Localization Algorithm Based on Grid Scanning
摘要
Abstract
This paper analyzes the range-free localization Algorithm APIT and API2T, points out the drawback of low accuracy and poor coverage. Wireless Sensor Network(WSN) localization algorithm based on grid scanning, called API3T, is proposed. In-To-Out error and Out-To-In error are reduced by redefining the neighbor nodes and it improves the strategy of the grid-scanning. Simulation experimental results show that the algorithm increases the localization accuracy and coverage.关键词
