Fairness of QoS Degradation in Multimedia Wireless Networks
Wangxin Xiao, Xue Zhang · 2007
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.
