A robust and distributed architecture for 5G-enabled networks in the smart blockchain era

Internet-of-Things (IoT) integrates ubiquitous computing to extend the Internet connectivity to the various application environments such as e-Health, smart cities, cyber-physical systems, etc. It connects the real-time objects to experience high-speed data transfer in 5G network deployment. It may periodically collect and process the data to control the access mechanism that utilizes a dedicated network protocol to fetches the information from different network domains. However, most of the access mechanisms cannot be applicable to the industrial application as it is based on a centralized architecture. This architecture has a complexity of computation overhead to deteriorate the performance of device-to-device (D2D) communication. In the industrial sectors, security and privacy preservation are majorly concerned to perform expensive operations and to prevent malicious cloud servers. Moreover, the real-time objects should be coordinated to optimize communication efficiencies. Thus, this paper presents a robust blockchain-based lightweight distributed architecture (RB-LDA) for 5G-enabled networks. The proposed RB-LDA authenticates the device access that advertises genuine data possession to restrict the key exposure. Moreover, the qualitative analysis proves the identity management continuously monitors the activities of IoT devices to perform a better auditing process. Above all, the experimental analysis shows that the proposed RB-LDA can achieve better data privacy to preserve sensitive information against the trusted third parties.
