During the previous decade, the internet of things has revolutionized the ever-present computing with a multitude of applications designed around numerous forms of sensors.
There is now a thriving trend in the integration of sensors and sensor-based systems with cyber physical systems, device to device communication. Fifth generation wireless are on the horizon where the IOT is taking center stage as devices are expected to form a dominant portion of this 5G network paradigm.
As the count of mobile hosts is increasing it will exceed a billion hosts. This upsurge in the number of mobile devices is intersected with the evolution of internet of things technology.
These interactions between a large number of heterogeneous devices increase a substantial demand on providing high connectivity, extremely highdata rates, low latency, designing special applications to serve the IoT and many other communication requirements.
IoT technologies such as machine-to-machine communication accomplished with intelligent data analytics which is expected to drastically change the landscape of various industries.
The emergence of cloud computing and its extension to the fog paradigm with the proliferation of intelligent ‘smart’ devices is expected to further lead the innovation in IoT.
These developments excite us and form a motivation to survey existing work by designing new techniques, and identifying new applications of IoT. Researchers, scientists, and engineers face emerging challenges in designing IoT based systems that can efﬁciently be integrated with the 5G wireless communications.
Due to the enormous data exchanged among a huge number of connected devices to form the IoT, the need to provide extremely increased capacity, high data rate and high connectivity rises. Hence, 5G wireless networks are considered as a vital driver for IoT.
In order to satisfy the expanded requirements of IoT drives several types of network are competing to ensure the connectivity which is necessary for the IoT applications.
5G will play a dormant role as an infrastructure to facilitate the connectivity of the large amounts of the connected devices to the internet. The development of the 5G pledges to provide extremely high data rates, consequently low latency and high integrity.
Also, the nature of the 5G cellular network supports the heterogeneity of connected devices in the IoT. In order to achieve the requirements to solve the challenges that need to be addressed by enabling the technologies that involve 5G are Network function virtualization, Wireless SDN, D2D, massive MIMO, Ultra-densification etc.
The 5G is expected to achieve certain requirements to be able to serve the various types of devices and applications.
High Data Rate:
With the outbreak of using networks in applications that require fast communications, there is a need for a high data rate which is increasing speedily.
Over years, reaching a high data rate in the wireless network is one of the prominent factors to evaluate the performance of the networks. Data rate has two main metrics that characterize the network are cell-edge data rate and area capacity.
Latency is the time required to transfer the data from source to destination via a network. The RTT latency of LTE is about 15 milliseconds which is expected to be reduced to 1 ms in order to satisfy the requirements of the 5G.
This is the reason there is a need to reduce latency within 5G as there is an increase in the use of real-time interactions in many applications, which requires no delay to enhance the user experience.
With designing LTE and then 5G wireless networks, the growing number of mobile phone devices should be taken into scrutiny. Serving and handling the number of devices need a dynamic scalable network. Providing high scalability for cellular networks requires enough frequency spectrum resources and efficient media control.
IoT is the very near future concept that frames our lives which is one of the enabling technologies for 5G cellular systems. The role of 5G cellular systems in the development of IoT systems provides a comparative analysis for some of IoT connectivity landscapes.
