Abstract :
The scarce wireless bandwidth motivated adaptive multimedia services where the bandwidth of an ongoing call can be dynamically adjusted. We consider multiple classes of adaptive multimedia services and assume the prioritization among classes in the bandwidth adaptation. A threshold-type call admission control algorithm is proposed and a product-form solution is derived. Also, we formulate a nonlinear programming model to find out threshold values for optimal solution. Numerical results show that the proposed method guarantees maximum revenue while satisfying the quality of service requirements
