Optimizing Mix-zone Coverage in Pervasive Wireless Networks

Jean-Pierre Hubaux, Igor Bilogrevic, Murtuza Jadliwala

Location privacy is a major concern in pervasive networks where static device identifiers enable malicious eavesdroppers to continuously track users and their movements. In order to prevent such identifier-based tracking, devices could coordinate regular i ...
