Towards a Resource-aware Thing Composition Approach

© 2019 IEEE. This paper addresses the silo concern that undermines the participation of IoT-compliant things in composition scenarios. By analogy with composite Web services, each scenario is specified in terms of choreography and orchestration and at design-time and run-time. To define things\u27 execution behaviors during composition, a set of transactional properties known as pivot, retriable, and compensatable, are used allowing to decide when thing execution should be confirmed, rolledback, or stopped. Along with these properties, another set of availability properties known as limited, renewable, and nonshareable specify the resources that things consume at run-time. Not all resources are always available and hence, could impact the execution of thing composition scenarios. A case study related to Industry 4.0 is used to motivate thing composition
