The Internet of Things (IoT) is a promising technology which tends to revolutionize and \nconnect the global world via heterogeneous smart devices through seamless connectivity. The current \ndemand for machine-type communications (MTC) has resulted in a variety of communication technologies \nwith diverse service requirements to achieve the modern IoT vision. More recent cellular standards like \nlong-term evolution (LTE) have been introduced for mobile devices but are not well suited for low-power \nand low data rate devices such as the IoT devices. To address this, there is a number of emerging IoT \nstandards. Fifth generation (5G) mobile network, in particular, aims to address the limitations of previous \ncellular standards and be a potential key enabler for future IoT. In this paper, the state-of-the-art of \nthe IoT application requirements along with their associated communication technologies are surveyed. \nIn addition, the third generation partnership project cellular-based low-power wide area solutions to \nsupport and enable the new service requirements for Massive to Critical IoT use cases are discussed in \ndetail, including extended coverage global system for mobile communications for the Internet of Things, \nenhanced machine-type communications, and narrowband-Internet of Things. Furthermore, 5G new radio \nenhancements for new service requirements and enabling technologies for the IoT are introduced. This \npaper presents a comprehensive review related to emerging and enabling technologies with main focus on \n5G mobile networks that is envisaged to support the exponential traf c growth for enabling the IoT. The \nchallenges and open research directions pertinent to the deployment of massive to critical IoT applications \nare also presented in coming up with an ef cient context-aware congestion control mechanism.
