Performance Evaluation of Cooperative Positioning with User-Terminal Collaboration

Abstract

User terminal collaboration is an emerging strategy for realizing spectrum- and energy-efficient wireless communication systems while improving positioning accuracy for advanced location-aware services. In this paper, we evaluate the achievable performance of a received signal strength (RSS)-based cooperative positioning scheme with user terminal collaboration, where the RSS is shared among users through direct inter-user communication at a higher frequency band. Simulation results show that user terminal collaboration significantly improves positioning accuracy in various evaluation scenarios.
