Video streaming applications over wireless networks have been turned out to be immensely popular in recent times. In this thesis, we study the buffering schemes streaming in heterogeneous wireless networks for the VBR video. An analytical framework is presented to derive the number of expected jitters and buffering delay in average. Through experimenting with a wide range of buffering schemes, we quantify the benefits over heterogeneous wireless networks of incorporating user location information in streaming. Second, we consider the delivery of scalable VBR video streams over wireless channels. To improve the combined system performance of video play out smoothness and frame quality based on the feedback information of wireless network estimation, buffer content and playback situation we propose adaptive rate control algorithms. The non-control policy is compared with the streaming quality which is improved significantly by proposed adaptive rate control algorithm.
