Internet of Things in the 5G Ecosystem and Beyond 5G Networks

With the rapid development of technology, the internet of things (IoT) has been an integral part of human society. The expansion and usage of IoT are further being accelerated by the global rollout of 5G cellular technology. The 5G and beyond wireless communications are especially focused on IoT requirements and use cases. One hundred percent coverage and connectivity are promised by the 5G beyond cellular network. The IoT devices may have to connect to any other known or unknown devices for sharing information, which urges different connectivity quality as well as different security and privacy requirements. In this chapter, the authors have explored the usage of 5G network slicing to cater to the diverse IoT connectivity requirement such as latency, bandwidth, and reliability. Moreover, as IoT devices may need to connect to other devices for various purposes, there is a need for trust evaluation among IoT devices. This chapter also discusses the establishment of social relationship among IoT devices to maintain privacy and security requirement through trust management.
