A Novel Mobility Management Protocol Supporting Network Seamless Roaming

New wireless applications have grown very quickly in recent years. In some cases, several nodes need to move as a whole while the traditional mobile IP can't support a network roaming together. Improved Mobile IP-Roaming Supported protocol (IMIP-RS) is proposed in this paper. In IMIP-RS, the distance between mobile nodes and the domain agent can be multi-hops while the value in MIP is only 1-hop. It combines handoff and buffer technologies in layer 2 with extended mobile IP technology in layer 3. It allows a roaming net to keep normal communication during fast moving.
