A fast and efficient authentication protocol for a seamless handover between a WLAN and WiBro

A wireless network has a handover problem between heterogeneous or homogeneous network entities. We describe in this paper a handover scenario between a WLAN and a WiBro network and propose a fast and efficient authentication scheme for the handover between a WLAN and a WiBro. In the scheme, a Serving Network(SN) plays a key distribution center role so that the Mobile Node(MN) can be quickly associated to a Target Network(TN) before starting a full authentication scheme where a remote Authentication Center(AC) is involved.
