AB  - Device-to-device (D2D) communication in cellular networks enables mobile users in proximity to communicate with each other without the intervention of infrastructures such as base stations (BSs).
Accordingly, networks should configure a cluster for cluster-based D2D content sharing. However, potential threats may arise since signaling among D2D devices is not mostly controlled by the centralized entity (e.g., BS). In this paper, we investigate a quality of service (QoS) degradation attack where channel feedback is incorrectly reported by the attacker (i.e., channel state information (CSI) forgery) in order to decrease the cluster sum-rate in a cluster-based D2D communication scenario. We first derive a closed-form of the cluster sum-rate under the QoS degradation attack. We also analyze the effect of a threshold-based defense scheme on the cluster sum-rate and further evaluate the impact of the QoS degradation attack using a system-level simulator in 5G networks (i.e., Simu5G).
