The continued advancement of wireless technology resulted in the enhancement of capacities and capabilities of mobile networks. There was a gradual improvement from the earlier networks which were based on analog switching and offered voice only services with several limitations of quality, capacity, and coverage to the modern digital networks offering great coverage and capacities to connect billions of users and devices while providing a wide range of services. The arrival of new technologies like Long Term Evolution- Advanced (LTE-A) and Fifth Generation (5G) has ushered in revolutionary improvements in terms of data rates, bandwidth, and latency, number of connected devices, network availability, and coverage. The new focus area is the Internet of Things (IoT), Internet of Everything (IoE) ecosystem where billions of mobile nodes, devices, sensors, and other information gathering instruments are connected through a combination of networks using different kinds of technologies. IoT is giving a new meaning to communications and information technology. New applications of IoT in the most diverse areas are emerging at a very rapid pace and it is expected to witness exponential growth in the near future. Some of the application areas where IoT has been successfully implemented include smart cities, smart transport, energy management, healthcare systems, environment monitoring systems, smart monitoring and control in industries.
