2 Internet of Things (IoT)
IoT architecture is divided into 3 layers, IoT device layers, IoT oriented Cloud
Networks and Platforms, and IoT devices. We are going to discuss all three layers in
detail (Fig. 1).
IoT device layer
This layer consists of devices capable of identify, sense and actuate capabilities
for interaction with that physical environment. These devices may consist of RFID
tags, Wireless sensor motes, smart cars, industrial appliances, wearable IoT devices,
etc.
IoT oriented Cloud Networks and Platforms
Due to the emergence of 5G or 6G networks in the industry and academia, a huge
number of IoT devices have been launched into the market for sensing, actuation,
accounting resource constraints, battery life, etc. To overcome this problem, two
major solutions have been proposed to overcome this increasing demand and supply
terminology. IPv6 based IoT protocol stack, Cloud, and edge computing.
Application Layer
This layer is used to provide the final service to the end-users. The major use cases
in this layer will be related to smart cities, smart homes, military appliances, Health
