Exploiting Opportunistic Interactions for Localization in Heterogeneous Wireless Systems (original) (raw)

Abstract—This paper addresses the problem of localization in mobile networks. Our goal is to make localization possible even for off-the-shelf communication devices like smartphones or sensor nodes, not equipped with GPS or operating in areas where the GPS does not work well. In our approach, a user estimates its position by exploiting opportunistic exchanges with other devices (peer devices). The localization information provided by peers include their own position estimation and can be used even though it may be highly inaccurate.
