摘要：With the rapid expansion of wireless technologies, the deployment of video streaming services has turned into more popular over the heterogeneous wireless networks in recent years, significantly enhancing the user experience. Generally, the heterogeneous networks are considered vertical handover in which the link capacity is varied significantly because the performance and quality of service of video are affected by the network status. The enriched performance and accessibility of various wireless access technologies are stimulated towards increased utilization mobile users. In such a network it is dominant for transfers to continue seamless connectivity and a satisfactory quality of service for mobile users. Therefore, providing the seamless handover and service quality promises is one of the key matters for video streaming services. The aim of this paper is to present an SINR-bascd unified procedure of available network and mobility behavior based on the standard of IEEE 802.21 media independent handover, the cooperative Proxy Mobile IPv6 and signal to interference noise ratio to assist lessening of the handover period during the video transmission. This paper also presents both horizontal and vertical handover simulation efforts based on the performance of handover metrics under various existing protocols in terms of packet and frame loss, handover latency, and peak signal noise ratio. Simulation results show that the proposed SINR-based unified procedure performs better quality of service efficiency for both horizontal and vertical handover.
