Algorithm for TOA-based indoor geolocation

A new indoor geolocation algorithm based on time-of-arrival (TOA) range measurements in a wireless network is presented. The algorithm, referred to as closest neighbour with TOA grid (CN-TOAG), is described and its performance compared with traditional least-squares (LS) methods.
