geant Software-Defined Networking in Heterogeneous Radio Access Networks

Integrating different wireless access technology to provide users with data service will definitely result in a heterogeneous radio access network. Moving from one wireless domain to another causes traffic being switched from one interface to another. This results in a reestablishment of TCP connection due to the change of the assigned IP address. Frequent handovers may force users to perform re-logins or application restarts, which undoubtedly jeopardize the quality of experience. This vertical handover problem will not be trivial as mobility is becoming a dominant factor in communications. This presentation provides a possible solution and research direction for vertical handover by leveraging the concept of software-defined networking together with existing proposals.
