Sažetak
The dissertation presents an architecture and an implementation of efficient and personalized content dissemination service targeting mobile users. The service enables information publishers to publish the content for numerous users based on the publish/subscribe interaction style. Service personalization is achieved through subscriptions: Users define subscriptions to express their interest in receiving certain content types. The published content contains non-realtime data of variable bandwidth demands (short text messages, images or video clips) and the publishing time is usually randomly determined. Furthermore, the service enables personal mobility, i.e., a user can receive the content in various networks applying different terminals. The thesis investigates two aspects of content dissemination. Firstly, a mathematical model of distributed publish/subscribe systems is presented, followed by the definition of routing algorithms that support publisher and subscriber mobility. Secondly, the thesis proposes a software architecture for content dissemination services based on a designed publish/subscribe Web service.
