Distributed computing pervasiveness is nowadays undeniable, and will continue to grow as the usage of device-to-device communications and the number of connected things populating our daily environment increase. Due to the connectivity disruptions induced by the mobility of devices communicating through short-range wireless interfaces and by the sleep phases of devices, it is often difficult to exploit the resources offered by the connected things forming these pervasive environments through the services they provide, and even harder to compose these services together so as to provide users with more useful and sophisticated services. This paper presents a service composition system adapted to opportunistic networks. This composition system relies on a service provision platform that exploits opportunistic networking and computing techniques to cope with connectivity disruptions. Service composition is performed dynamically, according to users’ interests. A multi-strategy scheme is used for the invocation of composite services, and a recovery mechanism is possible through partial invocation. This paper also presents the evaluation of the proposed composition system on two different scenarios: one involving people roaming in an open area, and another one involving spectators of a running event.
