Radio tomographic imaging using extremely resource constrained devices

This paper presents a simple and cost effective method for radio tomographic imaging (RTI) using extremely resource constrained devices. The idea is to measure and analyse packet loss rates under various power levels and obtain images of objects in an interested area. We have implemented an experimental prototype for the RTI system using extremely resource constrained devices and results show that the packet loss ratio for RTI is a cost-effective method for image estimation and provides better results when the transmitted power is low.
