摘　　要：机会通信作为一种对无线通信系统设计具有革命性意义的概念正在受到越来越多的关注.目前对机会调度算法的研究往往采用不同的模型进行性能评价,使得不同算法之间很难直接进行性能比较.本文主要将各种用于机会调度算法研究的理论模型进行分类和比较,对几种典型的机会调度算法在各类理论模型下的性能评价指标、方法和结果进行讨论,最后探讨了该领域未来的发展趋势并给出了一些有待研究的方向.Opportunistic communication is receiving more and more attention as a concept that has recently revolutionized the way engineers think about wireless system design. Currently, opportunistic scheduling algorithms are studied based on many different models. Therefore, comparisons of results are sometimes difficult. This paper classifies and compares the models that have been pro- posed, and discuss the performance evaluation metrics, methods and results of several typical scheduling algorithms within these models.Finally, we discuss the future trends and present several topics remained to be studied in this area.
