Abstract

Recently, numerous location-based services have been developed for smartphones; among location-based services, proactive location-based services can serve smartphone users based on periodically collected location logs in background. However, these proactive services have not been widely used, mainly because most of them continuously consume too much battery power. Thus, for proactive location-based services to be successful, their battery consumption needs to be as minimized as possible. In this paper, we propose Variable-Rate Localization (VRL) mechanism in an effort to maximize battery lifetime for periodic localization without a significant degradation of its quality. Our mechanism extends battery lifetime of periodic localization more than any other previously proposed techniques have achieved before.
