Mipv6 Protocols: a Survey and Comparative Analysis

As the future generation networks are envisioned to be heterogeneous in nature, seamless mobility in such networks is an important issue. While IETF work groups have standardized various mobility management protocols, such as Mobile IPv6 (MIPv6), Fast Handovers for Mobile IPv6 (Predictive FMIPv6, and Reactive FMIPv6), Hierarchical Mobile IPv6 (HMIPv6), Proxy Mobile IPv6 (PMIPv6) and Fast Handovers for PMIPv6 (Predictive FPMIPv6, and Reactive FPMIPv6), out of which some are host based and some are network based, the decision regarding which protocol suits the future networks is still a research issue. The study of various mobility management protocols in terms handover latency and the number of hops is needed to evaluate these protocols. Even though much study has been done in literature in terms of handover latency, study still needs performance evaluation in terms of average hop delay. In this paper we study various mobility management protocols by applying simple numerical analysis. The study is carried out for performance evaluation of various mobility management protocols in terms of average hop delay, wireless link delay, wired part delay, and binding update and registration delay. In this work, the average hop delay is estimated in terms of total handover latency and total number of hops contributing to each protocol. The study enables us to make a few important observations regarding the performance of these mobility management protocols.
