Cooperative Mobile User Location for Next-Generation Wireless Cellular Networks

Along with a vision that foresees the fourth generation (4G) as based on a cellular system that will also support short-range communications among its terminals, in this paper we propose an innovative geolocation scheme that exploits such an architecture and combines long- and short-range location information in a novel location algorithm. The simulation results presented in the paper show that our proposed scheme permits to enhance the location estimation accuracy with respect to the actual stand-alone hybrid cellular solutions.
