Towards sustainable smart IoT applications architectural elements and design: opportunities, challenges, and open directions

The convergence initiatives of cloud technology and the Internet of Things (IoT) have demonstrated a massive rise of the futuristic technologies which ensure sustainable production development of IoT applications such as intelligent transportation, smart cities, smart healthcare, and other applications. These real-time applications are employing the information and communication technology as an efficient utility to support a ubiquitous approach in the industry so that any apparatus can seamlessly interact with different cyber-physical systems and may also share its information effortlessly. Although the amalgamation of cloud and IoT offers robustness pervasive computing scenarios that can achieve the composite service with high quality and acceptable cost, it may face several challenges and issues not only in performance but also in architecture. The main aim of this study is to offer a stander framework to investigator and application designer that how sustainability can be achieved using different quality of service metrics. This is an overview of some crucial issues of IoT and the relation between it and other technologies based on various platforms. Focus is given in this study to three of the most important IoT applications that require highly successful sustainability procedures which are presented. A brief discussion and statistical categories of the research techniques published from 2000 to 2020, which highlight sustainable IoT applications, are also introduced. The contributions of this study are as follows: (i) summarizing the organization and methodology of the most important sustainable IoT applications, (ii) discussing the main challenges of the sustainable growth of IoT applications, (iii) highlighting future research directions in the field of IoT, and introducing guidelines for open business opportunities.
