Radio Tomography Imaging Based on Distributed Wireless Networks and Experimental Research

Radio Tomography Imaging (RTI) is an emerging technology with Wireless Sensor Network (WSN) widely applied to regional target monitoring and positioning. This study explores target imaging based on tomographic imaging mechanism and the loss of multiple links in the wireless network. For this purpose, Link Quality Indicator (LQI) data and the network structure are examined to derive the method of target image reconstruction using the Orthogonal Matching Pursuit (OMP) algorithm for compressed sensing. In addition, the proposed method is evaluated experimentally.
