中文摘要： 泛在业务的质量受执行业务的终端设备的处理能力、终端之间通信链路的质量等因素的影响。因此需结合泛在末梢环境中终端能力有限及网络拓扑动态变化等特点，展开面向业务质量的多终端选择和维护关键技术的研究，为泛在业务提供最佳的网络资源配置，并维护业务的持续性和平稳性。针对目前多终端选择和维护管理研究中存在缺乏面向业务质量的网络业务关系模型、多终端选择机制未考虑多目标、缺少多终端动态维护机制等问题，本项目的研究内容为：1）建立面向业务质量的泛在末梢网络业务关系模型；2）面向单业务设计基于多属性决策的多终端选择算法，面向多业务建立均衡多业务质量的终端聚合机制及算法；3）提出用户影响最小化的多终端动态维护机制，包括设计备用终端集合的生成算法，并根据多终端修复策略提出业务恢复机制和算法。最后通过仿真实验来验证相应的机制与算法。通过上述研究，为面向业务质量的多终端选择和维护管理提供理论和技术基础。

英文摘要： The quality of a ubiquitous service is affected by the processing abilities of executive devices, the quality of communication links between them and other factors. Therefore, to make researches on key techniques about QoS-oriented multi-device selection and maintenance, it is necessary to consider the limit of device capability, the dynamic change of network topology and other characteristics of ubiquitous edge environments. By this way, the ubiquitous edge network could allocate the best network resources for the ubiquitous services and maintain their continuity and stability. The existing studies on multi-device selection and maintenance technologies show some problems such as lacking QoS-oriented network and service relationship model, taking no account of multiple targets in multi-device selection mechanism, short of dynamic multi-device maintenance mechanism and so on. In terms of these issues, the research contents of our project are as follows: 1) To establish QoS-oriented network and service relationship model for ubiquitous edge network; 2) To design single-service-oriented multi-device selection algorithm based on multi-attribute decision, to design multi-service-oriented device composition mechanism and algorithm to equilibrate qualities of multi-service; 3) To propose dynamic multi-device maintenanc
