Design of a Language for IoT Service Composition

Abstract

In the Internet of Things (IoT) ecosystem, multiple smart devices communicate among them and with people. Similarly, they are primarily characterized by remarkable detection and processing capabilities. On the other hand, a service composition (SC) task involves performing the orchestration or choreography of services. SC is frequently studied in the context of Web services (WS), where a series of standards have been developed and used in real-world implementations to support SC. Unfortunately, these standards are inadequate in the IoT paradigm, since IoT devices are based on data/events and the resources are restricted. This research work proposes the design of a language for IoT SC, while simultaneously discussing important literature on SC, business process, IoT service orchestration, and IoT service choreography. Finally, as a proof-of concept, we present a case study of IoT service composition in the healthcare domain for patients with overweight or obesity.
