Optimum Efficient Fast Handover Support for IPv6

---International Engineering Task Force (IETF) proposed MIPv6 and HMIPv6 both mobility management solutions to support the IP mobility. Although HMIPv6 is an extension of MIPv6 still there is handover latency and packet loss in HMIPv6.In this paper a scheme is presented that supports a fast handover efficiently in hierarchical mobile IPv6 networks (HMIPv6). In HMIPv6 when a mobile node (MN) moves from a one MAP region to another, then there is a interruption of connection as well as packet loss due to long handover latency. To overcome these problems, an efficient fast handover scheme is adopted from FMIPv6 to optimize the performance of the interMAP handover. In this paper the handover latency for MIPv6 & HMIPv6 is compared to the proposed scheme with analytical model. By analysis and by simulations, we show that the proposed scheme has better performance compared to MIPv6 & HMIPv6 in terms of handover latency and packet loss.
