An Enhanced Fast Handover Scheme with Crossover Router Pre-Discovery support in Mobile IPv6

This paper presents an enhanced fast handover scheme in mobile IPv6 named crossover based fast handover mobile IPv6 (X-FMIPv6). We propose a lightweight crossover router pre-discovery process that identifies the location of CR in advance, before the MN actually makes handoff. A tunnel is setup between Crossover Router and NAR to minimize not only the service disruption time but also the redundant routing and network resource utilization. The numerical results indicate that our proposed scheme can improve handover efficiency in comparison with other existing solutions.
