Enhanced IoT Composition Architecture based on DIY Business Process Modeling: CoAP based Prototype

Abstract

Internet of Things has been the focus of research and development in the recent years. This increased attention has resulted in various approaches for the realization of the vision that every physical entity should be a part of global network of things. Representation of real world entities as virtualized entities in the cyber world is one such approach where the behavior of virtual objects is exposed as services and it can be accessed and manipulated like real world objects. The problem with the implementation is that most of the users lack the skills to utilize the services of these connected objects to create their own applications. We present a novel Business Process Modeling based approach to provide an intuitive Do-It-Yourself interface for generic users to easily compose their own IoT applications regardless of their programming skills. The proposed architecture has been implemented as a prototype which utilizes Constrained Application Protocol for connecting the things. A primary performance analysis of the major functionalities has been presented in this paper.
