Abstract

The dynamics of the wireless links represent serious problems in guaranteeing quality of services (QoS). Combined with mobility, additional problems, arise like handoff delays and resource management, arise. In this work, we consider an interworking architecture composed of IEEE 802.11 and IEEE 802.16 access networks. We define a new set of Hybrid Units in charge of QoS management and handoff decisions, allowing to map quality of service classes, reduce the handoff blocking probability, and guarantee a fair distribution of users among the different access networks if they cover the same network area. The simulation results validate the efficiency of our approach.
