Abstract :
Wireless and mobile social networking service (SNS) utilizes location information to enrich user experience. A major challenge in location-aware SNS is its strict requirement in precision of user location, which generally cannot be met by the existing GPS or cellular networks. In this paper, we propose a user-level cooperative localization scheme that improves the precision of existing localization techniques. A mathematical model is developed and in-depth simulation is conducted to evaluate the performance of the proposed scheme.
