Modeling IoT Design Patterns Proven Correct by Construction

Abstract

Formal method techniques are used to model complex systems as mathematical entities. By building mathematical rigorous models of IoT design patterns, it is possible to verify their properties in a thorough fashion. In this paper, we propose a refinement-based approach for modeling IoT design patterns. It allows the modeling of correct by construction IoT design patterns. It takes advantage of formal methods by the specification of design pattern models with the Event-B method and checking the design correctness. Our goal is to design IoT patterns proven correct by construction to successfully apply them and promote their reuse. Our approach is experimented through pattern examples and we illustrate it with a case study in the health care domain.
