Abstract:

To improve the handover performance of real time traffic, Mobile IPv6 (MIPv6) and its enhancement mechanisms are studied. A new hybrid seamless handover scheme called IMIPv6 (Integrated MIPv6) is proposed, which integrates MIPv6, Fast Handovers for MIPv6 (FMIPv6), Hierarchical Mobile IPv6 (HMIPv6), buffer management, Link-layer Trigger (L2T) and bi-casting mechanisms. The IMIPv6 prototype and its test results are described. The handover delay, packet loss and handover signaling load of MIPv6, FMIPv6, HMIPv6 and IMIPv6 are simulated and analyzed with NS-2. The results show that IMIPv6 and FMIPv6 have the least packet loss and that IMIPv6 has the lowest handover delay and the biggest signaling load. IMIPv6 has advantages over MIPv6, FMIPv6 and HMIPv6 in handover speediness and smoothness, and thus is suitable for seamless handover of real time traffic.

Key words: mobile computing, integrated MIPv6, seamless handover, latency, loss rate, signaling load
