Media Independent Handover and Mobile IPv6-Based UDP Performance Evaluation Suite for Heterogeneous Wireless Networks

Integrating heterogeneous access technologies to provide users with always best connected services is one of the primary objectives of fourth-generation wireless technologies. The major research issue in an integrated framework is to enable mobile users with fast and smooth connectivity while switching between heterogeneous access technologies.
 In this paper, an integration framework for Wireless Fidelity/Long-Term Evolution access technologies is presented with IP Multimedia Subsystem for service provisioning. An inter-domain handoff scheme called SIP advanced handoff is proposed which utilizes improved Session Initiation Protocol (SIP) and Mobile IPv6 with a multilayer approach which enables fast and smooth connectivity with minimized handoff latency and improved throughput. A simulation is carried out using NS2, and the performance characteristics are studied. The measured handoff performance metrics reveal that successful video session handoffs are achieved with acceptable quality of services levels and further that the proposed scheme shows better performance than the conventional scheme.
