Comparative handoff performance evaluation of SINEMO and macro-mobility protocols in NEMO

NEtwork MObility basic support protocol (NEMO BSP) and seamless IP diversity based NEMO (SINEMO) provide seamless and uninterrupted connectivity to the mobile hosts in NEMO. SINEMO removes the limitations of NEMO BSP by utilizing advanced loss recovery mechanism and multi-homing feature of stream control transmission protocol (SCTP). Though HMIPv6 together with NEMO BSP improve the micro-mobility problem in NEMO but the significant handoff latency and related packet loss still occur in macro-mobility because the performance of macro-handoff in NEMO falls behind NEMO BSP. To improve the handoff performance of NEMO BSP in macro-mobility environment, FHMIPv6, the extension of FMIPv6 and HMIPv6 could be utilized. In this paper, handoff performance of NEMO BSP along with macro-mobility support of HMIPv6 (M-NEMO) and FHMIPv6 (FM-NEMO) are analytically compared with SINEMO based on handoff latency, handoff blocking probability, packet loss and location update cost during handoff. The numerical results show that FM-NEMO outperforms M-NEMO and SINEMO in terms of handoff latency, handoff blocking probability and packet loss during handoff and M-NEMO also performs better than FM-NEMO and SINEMO in terms of location update cost.
