Friis and iterative trilateration based WiFi devices tracking

The spreading of the WiFi networks allows new applications. New problems bound to the mobility of the terminals arise. This article addresses the service continuity in mobility which requires terminal positioning. The solution proposed is iterative trilateration for which the distances are computed according to the signal strength. This solution is implemented in GeoMoVie, the mobility component in a multimedia content streaming platform. It is tested and validated with a heterogeneous indoor test bed. It is also advantageously compared with related work approaches.
