We propose Pervasive Service Computing (PSC) as a Web service-centric solution to facilitate modern human daily activities. Pervasive Service Computing emphasizes service composition, building applications from services and controlling the execution of the applications. In this paper we first investigate the evolution of pervasive computing. We generalize our novel concept of pervasive service composition by examining scenarios. We identify two composition categories of service collaboration and coordination, and present a formal model of service composition. Moreover, we explain service collaboration and coordination models by examining use cases. We survey the state of the art on service composition as well.
