Best Effort Multimedia Services

In the wireless systems with time-varying channels, the resource allocation algorithm can exploit channel variation to enhance the system performance. We consider the video streaming service as the representative RT service since it generates massive traffic in comparison with other multimedia services. For the BE services, we consider the required average transmission rate as the QoS requirement, to prevent the long starvation of some users and the excessive delay of their packets. This policy is particularly helpful for the Internet services using the transmission control protocol (TCP).
