Optimization of distributed resource allocation strategies in wireless systems for maximizing QoS

In this paper, we consider that users receive data from multimedia traffic. Each traffic stream is associated with a virtual buffer or transmission buffer implemented at the base station. The packets in these buffers are waiting to be forwarded to the recipient user. Buffers are therefore powered by multimedia data streams. Therefore, a buffer may occasionally he empty so that it is not useful to allocate resources to this stream. Therefore, considering multimedia traffic, the problem is even more complex. Furthermore, we assume that each stream can have different needs in terms of quality of service. Indeed, the state of a buffer is not easily predictable since it depends on many factors: the statistical properties of the traffic to the user; the quality of the channel on the different frequencies; allocations made in previous TTIs. We take no restrictive assumption on each of these three points.
