Study of IoT Architecture and Application Invariant Functionalities

IoT is a conjunction of many technologies and it has spanned across diverse and multidisciplinary application domains. Each domain has its own set of application requirements thereby inhibiting the use of conventional programming models. As a result there is a strong need for intermediate software abstraction layer to hide various technological details underlying IoT. In this paper, we propose two high level concepts of IoT, first is the IoT architecture for systematic study of common characteristics and second is the IoT application invariant functionalities and programming patterns. We think that our work exposes a step forward to review on the overall IoT architecture and provides a lightweight approach when designing software abstraction layer with minimalist programming functionalities that are IoT application invariant.
