Making Use of Design Patterns in IoT Middleware Implementation

This paper describes the usage of object-oriented and microservice design patterns to enhance system maintainability. The project involved bringing together data from multiple sensor networks and providing single endpoint for client applications. The middleware consists of purpose-specific components, databases and various off-the-shelf IoT components. Key lessons learned include the role of design patterns in simplifying complex system interactions and improving understandability. The importance of a modular approach, where design patterns provide a structured framework that promote reuse of proven solutions and reduce technical complexity becomes clear during the implementation of the middleware.
