Title: Mobile IPv6 Micro-mobility Solutions

Abstract

IETF proposed Mobile IPv6 (MIPv6) to address the IP mobility problem in the
next generation Internet Protocol by which mobile nodes are reachable while
roaming in the Internet. Nevertheless, MIPv6 is optimized for macro-level
mobility. Hence, several micro-mobility (local-area) protocols were proposed
for fast moving mobile nodes. In this talk, I shall contrast and compare two
such proposals, namely Hierarchical Mobile IPv6(HMIPv6) and Mobile IPv6
Regional Registrations (RRMIPv6). In addition, network simulations results of
both apporahces versus MIPv6 will be presented. Within the local domain, the
performance of HMIPv6 and RRMIPv6 is much better than that of MIPv6, the
performance of HMIPv6 and RRMIPv6 is similar (e.g., for packet loss per
handoff), and MIPv6 slightly outperforms HMIPv6 and RRMIPv6 at higher mobile
node movement rates for TCP bandwidth measurements. Furthermore, some work in
progress concerning fault-tolerance in MIPv6 micro-mobility solutions will be
discussed.
