Definition, Challenges and Future Research for Internet of Things

This article aims to provide a review of Internet of Things (IoT), analyzing its significant challenges within the framework of existing research on the topic. The IoT is a contemporary technology that encompasses wireless telecommunication networks. It can be conceptualized as a smart and interoperable node integrated within a vibrant global architectural system, with the objective of achieving ubiquitous and uninterrupted connectivity. The IoT landscape encompasses various challenges that significantly impact its operational efficacy. The challenges can be categorized into two main groups: i) General challenges integrating heterogeneity, security, virtualization, and communication; and ii) Unique challenges including Quality of Service (QoS), wireless sensor network (WSN), and Radio Frequency Identification (RFID), which is considered a shared factor between both groups. The report additionally outlines the primary applications of the IoT.
