Proxy-based MOBIKE fast handoff for femtocell integrated mobile network

Recently, small base stations such as femtocell and picocell are drawing attention as new components of wireless access networks. These small base stations are used not only to expand the wireless area within a large building, but also to increase bandwidth capacity and reduce the load on the core network. If multiple femtocells are deployed in an office building to expand the communication area, a handoff mechanism between femtocells is required to support the continuity of data communication. Especially, real-time applications such as VoIP require a seamless handoff mechanism. In this paper, we propose Proxy MOBIKE mechanisms that can realize an efficient handoff between femtocells and mitigate the difficulty of femtocell implementation resulting from supporting multiple protocols. We also implement our proposed mechanisms to verify and compare their effectiveness.
