Abstract
In 2014, J. Stankovic identified the research questions and directions to achieve the vision of Internet of Things (IoT). In this paper, we explore the spectrum of research conducted in connection to these research directions: (1) massive scaling, (2) architecture and dependencies, (3) creating knowledge and big data, (4) robustness, (5) openness, (6) security, and (7) privacy. The methodology used in this paper is a systematic literature review. Security and privacy were the common research direction related to IoT. This showed that the common issues and challenges faced by IoT is on security and privacy. It is worth noting that while there is an increased concern on IoT devices’ dependencies, there are fewer studies conducted on that domain.
