Proxy Mobile IPv6 (PMIPv6) is the NETwork-based Localized Mobility Management (NETLMM) protocol where access network supports the mobility of a mobile node on behalf of the mobile nodes. Yet PMIPv6 decreases the signaling overhead and handover latency, however it suffers from a packet loss issue and extend authentication latency through handoff. There are several security threats to PMIPv6. In this survey several extensions of the mobile IPv6 is examined for enhancing the performance. As an outcome, the different extensions of mobile IPv6 like Hierarchical Mobile IPv6 (HMIPv6) and Fast handover for Mobile IPv6 (FMIPv6) has mainly focused for performance upgrading of MIPv6.
