In this paper we propose a novel technique for efficient video distribution over WiMAX networks. The technique incorporates resource distribution, scheduling and content-aware streaming of video taking advantage of a flexible QoS functionality offered by WiMAX. The proposed technique was thoroughly investigated using NS-2 software package under various real-life scenarios which included streaming video over MAC service connections. It is shown that the technique allows dramatic increase in overall network throughput, which is dependent upon the initial selection of WiMAX user parameters.
