Efficient importance-based MAC scheduling for video streaming in Bluetooth Piconet

摘要

In order to provide the high quality service for transporting video streaming in the Bluetooth Piconet, in which the bandwidth is limited and the structure is heterogeneous, a MAC scheduling algorithm for video streaming in the Bluetooth Piconet is proposed. The main idea of the algorithm is to model the video streaming and calculate the importance of the packet relative to the video quality before transporting. The packet on the transportation is scheduled by the importance in the MAC layer to attain the maximum perceived quality of the overall Slaves in the Piconet. The simulation shows that the proposed algorithm can assign the network resource more efficiently, and improve the perceived video quality of the Slaves in the Piconet more significantly in contrast with the other algorithms.
