Hybrid CIP/M&M for micro-mobility management under the multilayer wireless network

We reference the EVOLUTE (Reinbold and Bonaventure, 2003) (Information Society Technologies, IST project) that mingles session initiation protocol (SIP) with mobile IP (MIP) to support macro-mobility management and provide seamless multimedia services for roaming users. In the part of micro-mobility, we utilize multicast-based mobility (M&M) to assist with cellular IP (CIP) infrastructure. They cooperate not only provide fast handoff and deal with various kinds of handoff, but also suit the macro-mobility management (proposed by Evolutes) to support real time and non-real time data flows.
