| Popis: | This work investigates the impact of channel estimation errors from the perspective of physical layer security in relay assisted Device-to-Device (D2D) communication. Specifically, we derive a generalized closed-form expression of outage probability of the secrecy capacity of N hop relay based D2D communication system. A single eavesdropper is assumed to be present at each hop to intercept the confidential message. Best relay is selected among the cluster of M relays to form a secure link from source to destination. We then quantify the changes in secrecy performance of D2D systems for both certain and uncertain channel information. Analytical and simulation results are provided to validate the derived results. |
