Recent developments, application cases, and lingering issues on the path to a 6G IoT

The growing demand for wireless communication networks (WSN) has resulted in a rise in the importance of intelligent services that depend on the Internet of Everything (IoE). An assessment of Wireless Sensor Networks (WSN) that incorporates enhanced capabilities and state-of-the-art communication technologies is necessary. Although 5G connections show potential for facilitating various IoE-based assistance applications, they may not be adequate to fulfil all the requirements of emerging intelligent applications. The current limitations of 5G connections have resulted in an increased demand for the conceptualization of Sixth Generation (6G) Wireless Sensor Networks (WSN) as a potential solution. The integration of artificial intelligence (AI) into the 6G network will provide resolutions for complex issues related to network optimisation. Furthermore, researchers are currently investigating novel techniques such as terahertz and quantum networks to augment the capabilities of forthcoming 6G networks. The forthcoming 6G wireless network is required to fulfil the requirements of accommodating a vast number of users and data-centric applications. This article stands out from prior works by presenting a comprehensive review of the most recent advancements in 6G networking, encompassing network prerequisites and significant enabling technologies. Furthermore, the article provides a thorough analysis of use cases, comparing the functionalities of 5G and 6G systems. The objective of these solutions is to address the requirements of intelligent communities. This article presents an overview of potential research directions for the development of IoT networks using 6G technology.
