Abstract

Network mobility (NEMO) basic support protocol (BSP) and seamless IP diversity based NEMO (SINEMO) have been designed to provide seamless and uninterrupted services to the mobile hosts in NEMO. SINEMO outperforms NEMO BSP by utilizing the advanced loss recovery and multi-homing feature of stream control transmission protocol (SCTP). To improve the performance of NEMO BSP, we could utilize the services of on-board TCP (obTCP) which implements local retransmission mechanism in the wireless links to recover wireless losses quickly and effectively. In this paper, we analytically compare NEMO BSP along with obTCP and SINEMO based on end-to-end packet loss probability, end-to-end packet delivery delay, handoff latency, and throughput degradation time during handoff. The numerical results show that NEMO BSP when used with obTCP performs better than SINEMO.
