Signalling Cost Analysis of SINEMO: Seamless End-to-End Network Mobility
IETF has proposed Mobile IPv6-based NEtwork MObility (NEMO) Basic Support Protocol (BSP) to support network mobility. NEMO BSP inherits all the drawbacks of Mobile IPv6, such as inefficient routing path, single point of failure, high handover latency and packet loss, and high packet overhead. To address these drawbacks, the authors proposed an IP diversity-based network mobility management scheme called Seamless IP-diversity based NEtwork MObility (SINEMO). In this paper, they develop an analytical model to analyze and compare the signalling costs of SINEMO and and NEMO BSP. Their analysis shows that SINEMO reduces the signalling cost by a factor of two when compared to NEMO BSP.
