Popis: | A priority based packet scheduling scheme for video streaming (rtPS) over WiMAX networks, which corporate with a resource allocation algorithm, has been proposed in this paper. After resource allocation algorithm allocates all the resources available among service flows, packet scheduling algorithm schedules packets in each packet queue according to current byte loss rate of video streaming queue. Priorities of the video packets in the queue and delays of these packets until all the resources for this flow are used up. Simulation results show that the proposed algorithm has better performance for video streaming and can protect the packets which have higher priority from being left, so the video quality has some improvement. |
