英文摘要: The smart service of Cloud computing and Internet of things is a challenge to the future of the Internet. Based on service-aware, this project research semantic model of resource network and semantic policy routing mechanism, and provide theoretical foundation and key technologies for the dynamic matching between service demand and semantic network resource. The detailed contents are as follows: 1. Define the service demand and the semantic space of network resource, provide a context-aware communication model, and build a framework for semantic resource network. 2. Build service-aware semantic model for network resource based on domain ontology and constraint rules. Build reason rule sets based on artificial intelligent reasoning mechanism, Match, manage and schedule network resource adaptively on semantic layer. 3. Combine service demand and physical network state constraint, extending the routing mechanism by introducing ontology. Semantic networks physical network state will appear in expansion model of the routing topology. Different semantic policy routing and route optimization parameters are introduced to optimize performance of the semantic network resources. The research results try to provide a basis exploration for late-stage study on smart service in the future ubiquitous networ
