World of IOT and Its Challenges

: The Internet of Things (IoT), a new paradigm, has transformed traditional living into a high-tech lifestyle. Smart cities, smart homes, pollution control, energy conservation, smart transportation, and smart industries are among the changes brought about by IoT. Many significant research projects and investigations have been undertaken in order to advance technology through IoT. To fully realise the promise of IoT, numerous obstacles and problems must be overcome. These challenges and problems must be considered from a variety of IoT perspectives, including applications, challenges, enabling technologies, social and environmental implications, and so on. The primary goal of this review article is to provide a thorough discussion from both a technological and a sociological standpoint. The article investigates the Internet of Things' various challenges, critical problems, architecture, and significant application domains. The paper also discusses existing literature and how it contributes to various IoT elements. Furthermore, the significance of big data and its analysis in relation to IoT has been discussed. This page will help readers and researchers understand the Internet of Things and how it applies in real life. Because of the massive number of wireless devices, such as smartphones and the Internet of Things (IoT), and the recent exponential growth in mobile traffic, the wireless network industry has produced and amassed an unprecedented amount of data. According to the International Data Corporation, there will be around 42 billion Internet-connected devices by 2025, with 80 zeta bytes of data created during the same year. There is no question that a new age is dawning as IoT and Artificial Intelligence (AI) grow more prevalent in society, and when 5G technology is implemented, new ideas in all industries will be inspired. We are creating a hyper-connected world in which gadgets are employed for more than simply data transmission and are gradually becoming intelligent and aware of their surroundings as a result of IoT ecosystem innovation. Because of advances in sensing, data processing, cloud, and communication technologies, the systems can interact with the environment and optimise operations by learning via interactions. As a consequence, intelligent settings and self-aware, linked "things" will be developed for applications in health, mobility, the digital society, food, energy, and the environment .
