As the Internet of Things (IoT) As the Internet moves into its later stages, it becomes important to understand the different ways IoT could be used and the research challenges that come with those uses. IoT is expected to affect almost every part of daily life, from Smart Cities to Smart Healthcare, Smart Agriculture, Logistics, and Retailing, Smart Living, and Smart Environments. “Even though IoT technologies have gotten a lot better in recent years, there are still a lot of problems that need to be fixed. Since the idea of the Internet of Things comes from different technologies, there are bound to be a lot of challenges to research. Because the Internet of Things is so big and affects almost every part of our lives, it is a good topic for research in many related fields, such as information technology and computer science. IoT is making it possible to do research in new ways. This document shows how IoT technologies have changed recently and talks about their possible future uses and research challenges
