Abstract :
Localization is a key support service for all users of mobile devices. We envision a lightweight localization service for Smartphones that overcomes the limitations of existing GPS-based approaches, namely their high energy cost and their issues with coverage. Our localization service uses GPS only if available and necessary, and employs other methods, such as WiFi and GSM, to achieve its goal of ubiquitous and energy-efficient operation. In this paper, we discuss our preliminary results as well as our future research directions.
