Architecture of mobile node in heterogeneous networks

In the next generation communication systems, different kinds of wireless public access have become increasingly available in various areas, so mobile terminals should provide multi-interfaces technology. The most challenging problem is the seamless intersystem mobility across heterogeneous wireless networks and the guarantee of the best quality of service and security for applications and users with best cost. This paper presents a proposed architecture of the mobile terminal that manages the handoff decision taking into account preferences given by users, applications requirements and networks performances and capabilities using the IEEE 802.11u standard.
