Open Research Challenges and Blockchain Based Security Solution for 5G Enabled IoT

Internet of things (IoT) is an emanate automation in this competitive and innovative world. The emerging growth of IoT devices required high-speed Internet affinity, high data transmission, and low emission, etc. There are several limitations to existing communication technologies such as limited bandwidth, reduced network coverage, and scalability. Thus, IoT with an existing network is less capable to meet the above requirements. Therefore, there is a requirement for next-generation wireless communication 5G network to fulfil all these demands. This article presents an overview of 5G and IoT, as well as the integration of both technologies called 5G-enabled IoT, with their emerging technologies. Although, 5G enabled IoT is a powerful and prominent technology, it suffers from various technological challenges and compatibility issues. So, this paper also reveals the open challenges in 5G, IoT, and 5G enabled IoT. To address the security issue in 5G-IoT, it provides a solution using blockchain technology.
