| Summary: | 碩士 === 國立臺北教育大學 === 資訊科學系碩士班 === 97 === Recently, the applications and services for Vehicular Ad-hoc Network have been deployed in real life, including the provision of traffic safety and comfort services that the vehicular users can obtain traffic information or provision of service provider. In addition, context aware service has become an active research topic. In this study, we focus on developing context aware negotiation and reasoning mechanism for vehicular services to provide adaptive information. We intend to develop an automatic mechanism with which vehicular users need not to exhaustively search for services information by themselves. According to the vehicular services provision scenarios in vehicular ad hoc networks, the ontology for vehicular services is constructed. With the ontology, the semantic information between different vehicular services can be described. Also, the ontology is implemented with Web Ontology Language (OWL), and therefore can be reused and shared, since OWL is a standard proposed by W3C. We build rules based on vehicular services ontology editing with Protégé, user contexts and contexts from roadside base stations. And then we map the ontology to Jess facts in JessTab. Then, Jess is used to reason adaptive service for vehicular users. Through the context aware machines, the vehicular users can obtain vehicular services information automatically in vehicular ad hoc networks.
