摘要:Given the strict Quality of Service (QoS) requirements of video streaming, this paper proposes a novelsolution for simultaneous streaming of multiple video sessions over a mobile cellular system. The proposedsolution combines a buffer management strategy with a packet scheduling algorithm. The buffermanagement strategy selectively discards packets of a user from base station buffer whereas the packetscheduling algorithm schedules packets of a user according to its instantaneous channel quality, averagethroughput and playback buffer information. Simulation results demonstrate that the proposed solution iseffective in providing a continuous video playback with good perceptual quality for more users. If at least agood perceptual quality is to be satisfied for all users (QoS constraint of video streaming), then theproposed solution improves the system capacity by 40% over a conventional packet scheduling algorithm.
