In this paper, the problem of distributed opportunistic scheduling by mobile users is investigated for a wireless cooperative network. Based on coalition formation game model, a theoretic framework is built in which users cooperate in accessing the shared channel in an individual view of average throughput. To analyze users rational behaviors, we propose a coalition formation approach which guides cooperative delivery by mobile users in distributed manner. Under the approach, users form a coalition structure in a dynamic manner, for which an optimal distributed cooperative scheduling strategy is derived maximizing average network throughput. Based on individual utilities, users make their own decisions to join or leave a coalition. To obtain a stable coalition structure, a distributed coalition formation algorithm is designed to adapt coalitions to environmental changes. The effectiveness and efficiency are verified by numerical simulations.

本文研究了无线协作网络中移动用户的分布式机会调度问题。基于联盟形成博弈模型，建立了用户在平均吞吐量的个人视角下合作访问共享通道的理论框架。为了分析用户的理性行为，我们提出了一种以分布式方式指导移动用户合作交付的联盟形成方法。在该方法下，用户以动态的方式形成联盟结构，从而得出最优的分布式协作调度策略，以最大化平均网络吞吐量。根据各个公用事业，用户自己决定加入或离开联盟。为了获得稳定的联盟结构，分布式联盟形成算法旨在使联盟适应环境变化。通过数值模拟验证了有效性和效率。
