Abstract :
In this paper, the fairness of QoS degradation for multi-class and multi-priority discrete adaptive multimedia applications is studied in wireless/mobile multimedia networks. The concept of degradation factor (DF) and its definition are presented. Then, we propose a generalized proportional fair degradation principle minimizing the weighted sum of DF´s square (MWSDFS). This principle considers not only inter-class and intra-class priority but also user´s QoS degradation degree. At last, quantum genetic algorithm based solution is given for the problem, and the experimental results further validate the effectiveness of our proposed algorithm.
