Design and Use of the Callflow Module in Executable Choreographies for IoT

The Internet of Things (IoT) is an ecosystem of computer devices, people or animals which hold unique identifiers and have the ability to transfer data over the network without involving human-to-human or human-to-computer interaction. Over the years, there have been a number of challenges in building a scalable IoT system. These challenges include asynchronous communication, for which we propose a solution developed within the PrivateSky project [1], based on the representation of the asynchronous code as a set of phases in a workflow, which we will present in Section 4.
