ABSTRACT
The Internet of Things (IoT) is transforming our lives. IoT is an auspicious technology in which heterogeneous devices with embedded sensors are connected to a single platform and these devices can then interact with each other. As the demand for IoT is increasing, an enormous number of smart devices need to be connected, which requires a huge amount of data to be transferred between devices, large connectivity, high security and privacy. A number of challenges need to be overcome to complete the vision of global connectivity using IoT. Many communication technologies like Wi-fi, LoRa and long-term evolution (LTE) are currently used in IoT networks, but these technologies have many shortcomings. 5G is seen as one of the best alternatives for future IoT. 5G cellular technology has many advantages like large coverage area, high data rate and lower latency, and allows more connected devices. For massive and critical IoT applications, 5G is one of the most widely researched areas. This chapter presents some of the emerging applications of IoT based on 5G cellular technology, together with challenges and future research directions for machine-to-machine communication.
