基于RSSI的室内定位算法优化技术
Indoor positioning optimization techniques based on RSSI
摘要
Abstract
Localization is very important in Wireless Sensor Network(WSN). In order to solve the problem of a major error of the indoor positioning based on RSSI, this paper proposes an improved scheme to provide higher localization accu-racy by analysing RSSI-based distance estimated model. In this scheme, environmental parameter fitting will be executed in the divided child areas which are segmented from the overall environment, and then the three reference nodes of the highest reliability which is measured by weights are taken to complete the localization. Through the experiment on Zigbee module, it shows that the proposed method can obviously improve the localization accuracy.关键词
