Analysis of vertical handover latency for IEEE 802.21-enabled Proxy Mobile IPv6

Low handover latency and IP session continuity are envisioned to be important factors for realizing next-generation all-IP heterogeneous wireless networks. To meet these constraints of the next generation networks, Proxy Mobile IPv6 (PMIPv6) has been considered as one of the IP mobility management protocols in recent years. Much research about the performance analysis of PMIPv6 has been done. However, a PMIPv6-based vertical handover and its performance analysis for heterogeneous wireless networks have not been considered yet. In this paper, we present a performance analysis of vertical handover latency for IEEE 802.21-enabled PMIPv6. Results of the performance evaluation show that the handover latency of PMIPv6 can be reduced with the IEEE 802.21.
