基于锚节点和高斯函数的测距算法
Ranging Algorithm Based on Anchor Nodes and Gauss Function
摘要
Abstract
Due to Gauss model has larger ranging error because of environmental path dispersion index, Reference-G mode is proposed. This mode uses Gauss distribution function to filter small probability Received Signal Strength Indicator(RSSI) values, and uses the known distance and measured RSSI between anchor nodes to correct the distance by being measured RSSI value, thus path dispersion index is eliminated. Simulation result shows that the ranging of Reference-G is independent on environment, and location errors in different environment are almost equal. The number of anchor nodes in Reference-G is less than 1/3 of Gauss mode with same errors.关键词
