A REVIEW ON SMART DEVICES, NETWORKING TECHNOLOGIES AND SECURITY IN NEXT-GENERATION IOT SYSTEMS
Main Article Content
Abstract
The digital environment has been completely transformed by advancements in the Internet of Things (IoT), which have led to the creation of intelligent, interconnected systems that integrate smart devices, advanced networking technologies, and adaptive security frameworks. The main elements propelling next-generation IoT systems are thoroughly reviewed in this paper. It classifies smart devices based on their functionalities and explores their benefits in enhancing automation, energy efficiency, and remote monitoring. Communication between devices may be made low-latency, scalable, and energy-efficient with the help of emerging networking technologies like 5G, Low Power Wide Area Networks (LPWAN), Software-Defined Networking (SDN), and network slicing. It is anticipated that integrating artificial intelligence (AI) into the Internet of Things would revolutionize it, especially in the domains of intelligent decision-making, predictive analytics, and real-time data processing. In this investigation, end-to-end encryption, blockchain-based authentication, and mechanisms for controlling access, such as Role-Based Access Control (RBAC) are examined as ways to protect user privacy and data integrity. According to the paper, AI, smart devices, and advanced networking combine to create autonomous, real-time systems in several domains, such as health care, smart cities, and industry automation. Despite advancements, interoperability, data privacy, and energy limitations remain problems, highlighting the necessity of more research into standardization, low-power cryptography, and AI-enhanced frameworks
