摘要

对无线/移动多媒体网中多服务类、多优先级的适应多媒体应用QoS降级的公平性问题进行了研究。提出降级因子加权平方和最小的降级原则

不但考虑了类间和类内优先级

而且考虑了用户的QoS降级深度。接着

证明对离散型适应多媒体应用

降级因子加权平方和最小的降级原则满足广义的按比例公平性

而对连续型适应多媒体应用

满足按比例公平性。最后

用量子遗传算法对所给问题进行了求解

结果进一步验证了所提算法的有效性。

Abstract

The fairness of QoS degradation of multi-class and multi-priority adaptive multimedia applications in wireless/mobile multimedia networks was studied.A degradation principle minimizing the weighted sum of degradation factor’s square（MWSDFS） was proposed

considering not only inter-class and intra-class priority but also user’s QoS degradation degree.Then

the degradation principle of MWSDFS is proved satisfying the generalized proportional fairness for discrete multimedia applications

and proportional fairness for continuous adaptive multimedia applications.At last

quantum genetic algorithm is used to solve the given problem

and the results further validate the effectiveness of the proposed algorithm.
