The Internet of Things (IoT) is going to be a few of the most influential and critical role spectators in the post-5G and 6G wireless networking paradigm because IoT is being deployed in a variety of applications and services such as smart towns, smart homes, savvy environment monitoring, smart medical care, smart factories, savvy agri-business, and so on, with the goal of enabling intelligent coordination and efficiency improvement. An intelligent reflective surface (IRS) is a notable invention that will be included into 6G wireless systems to optimize the electromagnetic propagation atmosphere in a configurable or adjustable manner in order to increase communication between the transmitting and receiving devices. The study aims to increase IoT service coverage by employing IRS in micro wireless transmission. As a result, in terms of receiving power, the research investigated and compared the effectiveness of traditional small cellular connectivity with IRS-enhanced small cellular transmission in the 6G wireless IoT environment. According to the findings, deploying IRS greatly improves coverage for IoT-related services.
