A Novel Mobility Management Protocol Supporting Network Seamless Roaming

Free registration required

Executive Summary

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.
