Abstract

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. For application based handover decision, mobility management as well as transport/application protocol control adaptation for handover performance optimization is made with the help of Media Independent Handover (IEEE 802. 21) Frame work. Through the simulation results, it is shown that multi-layer handover triggering of the proposed concept enhances the QoS of the application services. The handover decisions are made when the QoS requirements of an application is not satisfied as well as when a mobile user moves out of the current access network in overlay network environments. It is also presented that per-application handover based on the proposed platform enhances the QoS of the application services compared to the handover approaches which make every on-going service flows handover together to the same access network.
