Abstract :
The spreading of the WiFi networks allows new applications. New problems bound to the mobility of the terminals arise. In this article, we deal with the requirements and the solutions to address the service continuity in mobility. These requirements are integrated in mobility management middleware. It requires terminal positioning. The solution proposed is trilateration for which the distances are computed according to the signal strength. To provide the service continuity, the mechanism called handover is used. It requires an anticipation which is realized through mobility prediction. The handover is done transparently by an adapted protocol. All of these functions are implemented in GeoMoVie, the mobility component in a multimedia content streaming platform
