An IEEE 802.21-based approach of designing interoperability modules for vertical handover in wireless hybrid access networks

In this paper we described the generic design of software interoperability modules for vertical handover in wireless hybrid access networks. The proposed approach conforms to the IEEE 802.21 Media Independent Handover (MIH) standard and fits into our architecture for reconfigurable interoperability of wireless communication systems, RIWCoS. The next step of our work will be the implementation of concrete media dependent modules following the proposed approach, and their integration into the overall system.
