Service-Oriented FMIPv6 Framework for Efficient Handovers in 4G Networks

Mobile IPv6 (MIPv6) standardized by IETF, is expected to support the global IP mobility. Fast Handovers for Mobile IPv6 (FMIPv6) is further proposed to improve the performance of MIPv6. However, FMIPv6 only concentrates on the protocol operation while it does not address other critical issues, such as the L2 and L3 identifiers mapping problem and precise L2 triggers generation. This paper proposes an efficient service-oriented framework for FMIPv6. In this framework, FMIPv6 is integrated with candidate access router discovery (CARD) mechanism, specified L2 triggers and different handover processes will be performed for different service types according to QoS requirements. The analytical and simulation results both show that the proposed scheme could achieve better performance in terms of handover latency.
