ABSTRACT A device-to-device (D2D) underlying cellular network is pervasive to support various wireless applications. However, due to the dramatic increase of data transmission in the network with limited amount of wireless resource, a few users may be required to temporarily disconnect from the network to avoid the interruption of data transmission in the whole network. A critical issue of determining the user access in D2D underlying networks is the authenticity of channel state information (CSI), and usually, a user with a higher CSI can be allocated a larger amount of wireless resource or have a higher probability of staying in the network. In this paper, we propose a blockchain consensus-based scheme to verify the authenticity of CSI and add the users who intentionally advocate a higher value of CSI into a fraud chain. Also, we consider both the cross-tier interference caused by a mobile user and the presence of a user in the fraud chain to determine the access of a user. The analysis results show that our proposed user access scheme can enhance the network performance by efficiently controlling the use access in mobile applications.
