Low Latency Proactive Handover Scheme for Proxy MIPv6 with MIH

This paper proposes a novel low latency handover scheme for Proxy Mobile IPv6 (PMIPv6) using Media Independent Handover (MIH) services. We analyze the major aspects that induce high latency during Mobile Node's (MN) handover within a PMIPv6 domain. Our analysis consists of Layer 2 (channel scanning, MN authentication, MN's profile acquisition) and Layer 3 (binding registrations and tunnel establishment) operations. By using MIH services we provide a solution that minimizes overall scanning delay at Layer 2, the information service provided in MIH can provide context transfers, and efficient triggering events can speed up handover procedure. Through the performance evaluations made in the OPNET network simulator we validate our proposed scheme.
