Joey Wilson and Neal Patwari of the SPAN lab have published a technical report entitled "Radio Tomographic Imaging With Wireless Networks." RTI is a technology that is capable of imaging and tracking objects within a wireless network. This report discusses the linear formulation and reconstruction algorithms that can be implemented using only received signal strength, and describes some results that we've obtained with a prototype implementation. This is still a work in progress, so please report any corrections that you find.
