Research on 3D Positioning Indoor Simulation Based on RSSI

Abstract

The growing demand for location-based services promote the development of positioning technology, but the traditional two-dimensional positioning has not fully meet the actual demand, three-dimensional positioning and has more practical significance and application prospects. RSSI-based ranging technology is a low-cost distance measurement technology and low complexity, has been widely used in wireless networks based on the distance of positioning technology. In this paper, through detailed analysis and Research on the effect of RSSI, simulation implemented based indoor positioning. Experimental results show that after eliminating the effects of environmental factors, after mean filtering and data processing Gaussian model range accuracy has greatly improved, positioning error is smaller.
