Conflict Management for Media Services by exploiting Service Profile and User Preference

In this paper, we propose Context Manager to resolve conflicts for Context-aware Media services in smart home environments. Conflicts arise when multiple users access a Media service or when various Media services share limited resources to provide customized responses. In order to resolve conflicts among users, the Context Manager sums up preferences of users who collide with each other and recommends specific contents ordered by the summed preference. It also resolves conflicts among Media services by selecting a Media service with the highest preference. Furthermore, Context Manager resolves conflicts among Media services occupied by users with the Media service recommendation. During experiments on ubiHome, a smart home test-bed, the proposed method resolved conflicts among users and Media services while giving higher satisfaction to users than a resolution method selecting a specific user. Therefore, we expect the proposed management method can play a vital role in Context-aware Media services for offering personalized services to users by resolving service conflicts among Media services as well as users.
