Fair bandwidth allocation for multi-class of adaptive multimedia services in wireless/mobile networks

Adaptive multimedia services are very attractive in wireless/mobile networks since they can mitigate the fluctuation of resources. We consider some quality of service (QoS) aspects for multiple classes of adaptive multimedia services in wireless/mobile networks. They are QoS parameters for the bandwidth degradation, a call admission control scheme and a bandwidth allocation algorithm to satisfy QoS, and to utilize resources efficiently. Moreover, they are for multiple classes of users with fairness among classes and fairness within one class. The fairness among classes is achieved by partitioning the bandwidth resource according to arrival rates. The fairness within one class is achieved by fairly distributing the degree of bandwidth degradation among users. Simulation results show that the proposed scheme achieves good fairness for bandwidth and degree of degradation.
