MIH-Assisted PFMIPv6 Predictive Handover with Selective Channel Scanning, Fast Re-association and Efficient Tunneling Management

Abstract

In this paper, we investigate the major limitations of PFMIPv6, and explaine detailed lower layer procedures, which may significantly affect the handover performance. We propose a solution to reduce the overall channel scanning time by using IEEE 802.21 Media Independent Handover (MIH) services. MIH service is also used for efficient handover triggering and event notifications. In order to minimize the network attachment delay, we propose a fast re-association scheme for Mobile Node (MN). An efficient management of transient Binding Cache Entry (BCE) allows to eliminate out-of-order packet delivery and reduces the end-to-end delay at handover. Through the performance evaluations on OPNET network simulator, we validate that the proposed scheme provides better performance compared to PFMIPv6 and PMIPv6.
