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