A Novel Network Mobility Scheme Using SIP and SCTP for Multimedia Applications

Wireless networks of future generation are envisioned to be a combination of diverse but complementary access technologies that can give us a convenient wireless environment to access abundance of network resources so as to facilitate and enrich our everyday life. In such environment, seamless mobility support is the basis of providing uninterrupted wireless services to mobile users who roam between or among various wireless access networks. When users are now in a moving transportation carriage, e.g. a train that provides network service, the carriage can be regarded as a network which comprises a set of users and moves from one location to another. Network mobility protocol based on mobile IPv6 has some fundamental problems, such as header overhead and pinball problem. In this paper, we propose a novel method based on SIP and SCTP for network mobility to solve the MIPv6-NEMO problems. Experimental validation and performance evaluation are also performed.
