Evaluation of Fast PMIPv6 and Transient Binding PMIPv6 in Vertical Handover Environment

Recently, the IETF MIPSHOP working group proposes Fast PMIPv6 (FPMIPv6) and Transient Binding PMIPv6 (TPMIPv6) to reduce the handover latency and packets loss of PMIPv6. The research and standardization of FPMIPv6 and TPMIPv6 are just in the initial stage. The system performance analysis of them is benefit to the protocol design and deployment. In this paper, through the theoretical analysis and system simulation, we evaluate the handover latency of PMIPv6, FPMIPv6 and TPMIPv6 in vertical handover environment. Furthermore, in order to reflect handover performance more comprehensively, in system simulation, we also evaluate the UDP packets loss rate and the TCP throughput declining degree of such protocols. The results of theoretical analysis and simulation show that: (1) in vertical handover, the handover latency of FPMIPv6 is much larger than TPMIPv6 and PMIPv6. But the UDP packet loss rate of FPMIPv6 is smaller than TPMIPv6 and PMIPv6; (2) the handover performance of FPMIPv6-pre and TPMIPv6 much depend on MN´s residence time in signal overlapped area.
