Internet of Things (IoT) Applications, Tools and Security Techniques

The Internet of Things (IoT) has transformed cultural traditions into high-tech ones. Urban areas, smart industries, smart devices, environmental management, smart transportation, and energy conservation are examples of IoT-driven changes. IoT has its milestones which are gradually increasing as the technology is getting more modern. The primary objective of this proposed study is to give a comprehensive review of Smart City applications from both a technological and a sociological standpoint. Security, privacy, authentication, and trustworthiness for the end-users is the main feature of technology. There are several available ways in which different parameters of IoT can be managed among them NFC, RFID, and WSN are commonly used. This article will help users, scholars, and professionals acquire a better knowledge of the IoT framework, applications, technologies, and concepts related to security and privacy that have been implemented, thereby serving as a foundation for a seamless transition to the real world.
