Mobile IPv6 is the next generation wireless internet protocol to support IP mobility. One of the most important challenges in Mobile IPv6 is to provide the service for a mobile node to maintain its connectivity to the internet when it moves from one domain to another, which is referred to as handover. Because when performing the handover scheme, there is a period that the packets cannot reach the MN (Mobile Node) in time, the fast handover scheme is proposed to reduce the handover latency and packet delay. In this paper, we propose an enhanced fast handover scheme for Mobile IPv6. In our scheme, each AR (Access Router) maintains a CoA (Care of Address) table and generates the new CoA for the MN who will move to its domain. At the same time, the binding updates to home agent and correspondent node are proposed to be performed from the time point that the new CoA for MN is known by PAR (Previous AR). The performance analysis is provided in the paper. After the comparison with the existing fast handover scheme, we can see that the proposed enhanced fast handover scheme can achieve low handover latency and low packet delay.
