The challenges of the internet of things (IoT): Systematic literature review

The Internet of things market grew rapidly in recent years. The increased number of connected objects and the diversity of IoT services caused many challenges. The IoT links heterogeneity sensors from different networks in order to address users' needs. A systematic review study was accomplished to identify and clarify the challenges of the IoT with an initial result set of 811 articles, covering studies published from 2013 to 2019. 50 studies were selected and classified according to the study criteria. The results include highlighting the 10 main challenges with the IoT and introducing data security and privacy as major concerns. The lack of standardization and interoperability is also considered a critical challenge with the IoT. In addition, the descriptive results reported that most of the investigated papers are related either to industrial or technical aspect. A lack of other areas with the IoT, such as educational, social, and cloud, were reported as well.
