摘　　要：在泛在末梢环境中,为了减少协同方案维护代价,满足一定的业务质量需求,提出了一种基于终端干扰和链路稳定性的多终端协同维护机制(MDCMM)。该机制建立了协同方案维护模型,结合终端干扰和链路稳定性确定了维护指标,并使用动态规划思想优先选择可靠的协同方案,减少方案切换对用户的干扰,满足用户多样化的业务质量需求。经OPNET和MATLAB仿真实验,该机制具有较低的维护代价,并且协同方案切换更平滑,证明该机制能更好地保障用户体验。To reduce costs of cooperation solutions maintenance and meet certain demand of service quality, a multi-devices cooperation and maintenance mechanism（MDCMM） based on device interference ability and link stability was proposed. With amulti-devices cooperation model, and an evaluation index considering both the heterogeneous device interference ability and the link stability, MDCMM provides a maintenance mechanism of the ubiquitous service in a certain period based on dynamic planning optimization strategy, aims at reduces interference of cooperation solutions switching and meet users＇ diverse needs. Simulation results show that,compared with the existing mechanism,MDCMM has lower maintenance costs, smoother cooperation solutions, and better able to guarantee the user experience.
