A performance comparison of Mobile IPv6, hierarchical Mobile IPv6, and Mobile IPv6 regional registrations

IETF proposed mobile IPv6 to address the IP mobility problem in the next generation Internet protocol (IPv6) by which mobile nodes are reachable while roaming in the Internet. Nevertheless, mobile IPv6 is optimized for macro-level mobility. Hence, several micro-mobility (local-area) protocols were proposed for fast moving mobile nodes. We conducted a performance evaluation of mobile IPv6 and its proposed micro-mobility solutions, namely. Hierarchical mobile IPv6 (HMIPv6) and mobile IPv6 regional registrations (RRMIPv6). Our simulations showed that within the local domain, the performance of HMIPv6 and RRMIPv6 are much better than that of MIPv6, that the performances of HMIPv6 and RRMIPv6 are similar (e.g., for packet loss per handoff), and Mobile IPv6 slightly outperforms HMIPv6 and RRMIPv6 at higher mobile node movement rates for TCP bandwidth measurements.
