A Task-oriented Service Composition for Internet of Things

Abstract

Service-oriented computing has enabled dynamic composition of Web services to help users meet their task goals. However, one of the emerging issues in an Urban Computing (UrbComp) environment is to seamlessly utilize the new concept, Internet of Things (IoT) to compose and provide IoT-based services of local smart objects. This challenge is about enabling services that are actuated by Smart Objects (SmObs), supported and delivered from the perspective of users. In order to accomplish this goal, it is essential to integrate IoT-based services into the service composition framework to discover nearby SmObs and utilize their operations to deal with the high-level goals of users and dynamic changes of contextual information. We use the task-oriented computing approach to utlize the concept of IoT in an UrbComp environment. This approach represents users’ goals in tasks, which are then bound to available service instances. We describe an implemented prototype of our framework and demonstrate a scenario to show its use in a real life to illustrate its feasibility.
