A predictive resource allocation scheme that provides high wireless network utilization is proposed by dynamically reserving only those resources that are needed. The algorithm exploits the structure of the MPEG video stream and allocates bandwidth on a scene basis, wherein the mobile users change their bandwidth requirement only for scene boundaries. This will result in a high bandwidth gain, which will improve the overall network performance. The proposed scheme is dynamic and also facilitates bandwidth management. It automatically adjusts the amount of reserved resources, while the required QoS are also guaranteed. The algorithm is simulated and evaluated using model encoded video data.
