Extension of Fast Mobile IPv6 with multiple pre-registrations: Design and implementation

In IETFpsilas fast mobile IPv6, the mobile node may switches into the reactive mode of handover operation when the prediction of the movement is wrong. In this case, the mobile node may experience severe service disruption due to large handover latency and packet loss. In order to solve this problem, we propose a fast mobile IP handover with multiple pre-registration. In the proposed approach, the new IP addresses are prepared in advance at multiple locations where the mobile node may probably moves into. If the predictive mode of handover operation by FMIPv6 fails, the mobile node tries to move into the previously prepared locations. Therefore, delay time of generating new care-of-address is saved. We have built a prototype system, and measure the performance of the proposed system. The experimental results show that the proposed approach can reduce greatly the handover latency.
