Fast IP Mobility Management for Mobile Computing Service with Multiple Pre-Registration and Late Tunneling

In order to provide a low latency IP handover for real-time mobile and/or pervasive computing service, the IETF has specified FMIPv6 protocol. However, in FMIPv6, if a prediction about a mobile node movement is erroneous, both large handover latency and packet loss result. This is because the handover is performed in reactive mode, when the prediction is found to be incorrect. In this paper, we have proposed an intelligent mobile IPv6 handover scheme, called IMIPv6, which can remedy the above limitations of the FMIPv6. In the IMIPv6, multiple pre-registrations of CoAs, intelligent movement detection and late tunneling are employed to reduce handover latency and to eliminate packet loss. The simulation results show that the IMIPv6 can drastically reduce the handover latency, while eliminating packet loss.
