The Backward Fast Media Independent Handover for Proxy Mobile IPv6 Control Scheme (BFMIH-PMIPV6) over Heterogeneous Wireless Mobile Networks^*

Proxy Mobile IPv6 (PMIPv6) is a networked-based handover protocol for the IP layer, i.e., the layer 3 mobility management protocol. The fast handover control scheme can be integrated into PMIPv6 to improve handover latency. Since the handover performance of the predictive mode is better than that of the reactive mode, an issue should be considered is how to have a handover control scheme that can let MN have the higher chance of being in the predictive mode to improve the handover. In this work, the Backward Fast Media Independent Handover Control Scheme for Proxy Mobile IPv6 (BFMIH-PMIPv6) is proposed. The BFMIH-PMIPv6 integrated fast handover and IEEE 802.21 Media Independent Handover (MIH) Services with PMIPv6 to improve the handover performance over the heterogeneous wireless network. The proposed BFMIH-PMIPv6 can start handover preparation earlier to let MN have the higher chance of being in the predictive mode and build the tunnel in advance to reduce the packet loss situation and handover latency. Through the simulations for performance analysis, it shows that the proposed BFMIH-PMIPv6 can have better handover performance in terms of handover latency, packet loss rate, and throughput.
