Abstract
The Internet Engineering Task Force (IETF) offers the mobile IPv6 (MIPv6) to support the mobility management of the MN. However, mobile nodes supporting the MIPv6 suffer from long handover latency and can not support real-time multimedia service such as VoIP. The IETF offers the Fast Handover for Mobile IPv6 (FMIPv6) to solve the problem. However, in the network mobility (NEMO) architecture, we find that in some situations FMIPv6 may lose its strengths, and even incur longer handover latency. We propose a solution called enhanced fast handover for mobile IPv6 (E-FMIPv6) and utilize the mathematical analysis scheme to analyze the performance of the E-FMIPv6 in NEMO architecture. The numerical results show that the E-FMIPv6 improves the performance of the MN's handover in the NEMO architecture. To compare with the traditional FMIPv6, the E-FMIPv6 improves the packet delay and the handover latency in the predictive mode and improves the packet loss and packet delay in reactive mode. To compare with the MIPv6, the E-FMIPv6 can improve the handover latency, packet loss and packet delay in predictive mode and improve packet loss and packet delay in reactive mode.
