Executive Summary

With the advance of various wireless access technologies, the demand for a mobile user equipped with multiple air interfaces simultaneously executing diverse applications emerged. In such network environments, per-application mobility management is a key to allow each application of an end user device to dynamically and fully take advantage of the most suitable access technology. In this paper, an Application-oriented Media Independent Vertical Handover Decision (AMIVHD) mechanism for video transmission by a mobile user over heterogeneous network environment is implemented. The proposed concept enables the triggering of vertical handover decisions based on the quality measurements of video transmission in wireless networks.
