Probabilistic resource allocation under opportunistic scheduling in wireless networks with multimedia services

In this paper Opportunistic scheduling to achieve high throughput, while at the same time satisfy both long-term and short-term users' QOS constraints in wireless networks supporting multimedia services is adopted This is achieved via the transformation of the corresponding QOS Constraints into appropriate probabilities of accessing the systems' recourses. The users scheduling procedure considering their corresponding access probabilities is obtained through a new proposed scheduling policy which allocates them fixed weights, initially computed, under the assumption of Rayleigh channels. The derived users' weights ratios force the opportunistic scheduling policy, to meet the users' desired access probabilities and thus satisfy their respective QoS requirements.
