增强位置服务提供的整体适应性，是智能化服务的核心。本项目通过深入分析位置服务的移动和社会化特征，探索其语义位置组织、QoE评价、以及情境可表达的描述模型，提高服务的共享适应性；研究服务的抽象及其内部自主演化的容错和仿“生命游戏”的休眠机制，增强服务的鲁棒性；探索混合群智感知中态势感知的数据传输、和基于分布式规约和社区发现的情境数据融合方法，并引入情境更新策略发掘用户的个/群体综合情境特征，增强服务的情境适应性；采用能力驱动方法，引入虚拟实体和自适应定位模型，构建开放的服务发现框架，并通过QoE局部近似过滤进行服务选择，提高服务发现的需求适应性；在服务执行过程中，引入检查点Agent和环境驱动模型实现用户需求和服务资源双异常的监控处理，针对失效服务，探索考虑重定位的事务级可补偿服务替换方法，增强服务执行的异常适应性。研究成果将为位置服务体系构建提供理论和实验依据，为推动位置服务计算奠定基础。

It is the core of intelligent services to improve the comprehensive adaptability of the provisioning mechanism for LBS (Location-based services). This project will deeply analyse the mobile and social characteristics of LBS, and explore the organization of the semantic location, the QoE evaluation and the description model which can support the expression of the context, to improve the sharing adaptability of the service. The abstract method of the service and the mechanism of the fault tolerance via Self-evolvement and the sleeping via Life Game for the internal nodes are researched, to enhance the robustness of the service. Then the data transmission mechanism based on the situation awareness in the Hybrid Crowdsensing, and the fusion method of the contextual data based on distributed rules and the community detection respectively are explored, also the updating strategy of the context is introduced, to obtain the individual and the group context characteristics of the user, to improve the context adaptability of the service. An open service discovery framework was constructed according to the capability-driven method, by introducing the virtual entity and the adaptive localization model. And the service selection method via the local approximate filtering based on QoE is adopted in the framework, to improve the requirement adaptability of the service discovery. In the implementation of the service, the checkpoint Agent and the environment-driven model are introduced to achieve the monitoring and handling with the exception caused by both the user's needs and the service resources. For the invalid service, the service replacement mechanism with compensation-support based on transaction by considering the location update was presented, to enhance the exception adaptability of the service implementation. The outcomes delivered by this project will provide theoretical guidance and practical methods for the construction of the service system of LBS, and lay the foundation for pushing location-aware computing of LBS.
