IoT Composer: Composition and Deployment of IoT Applications

Abstract

The Internet of Things (IoT) consists of interconnected physical devices and software components. These connected things or objects exchange information in order to provide an end-user service. To fulfil this objective, such applications have to be designed by composing existing objects. However, this is a very difficult task mostly due to the heterogeneity and diversity of available objects. The IoT Composer tool was developed for supporting the development of IoT applications by first providing a behavioural model for objects and their composition. IoT Composer is developed as a web application that provides graphical support for composing available objects. The tool also provides automated validation techniques for verifying that the composition behaves correctly. Finally, a deployment plan is generated and can be run for effectively binding and instantiating all objects involved in the composition. IoT Composer was applied successfully to several real-world case studies. Video URL: https://youtu.be/6Cn3CUm5-qU.
