A Performance Comparison of FMIPv6 and HMIPv6,Optimization Techniques of MIPv6

Mobility management with provision of seamless handover is crucial for an efficient support of global roaming of mobile nodes (MNs) in next-generation wireless networks (NGWN). Mobile IPv6 (MIPv6) and its extensions were proposed by IETF for IP layer mobility management. Mobile IPv6 developed in 1997 is considered to be one of the key technologies for realizing mobile Internet which enables seamless communication between fixed line and wireless access networks. Now, users are able to establish and maintain a session between their computer and information network as they roam from one place to another. Once connected, a continuous session with no interruptions is provided. But the delay constraint, measured in terms of handover latency, is the crucial factor, which should be reduced.
