On Physical Layer Security over α - η -κ -μ Fading for Relay based Vehicular Networks

Abstract

In this paper, we study the secrecy problem for a relay-based vehicular network. We assume that the legitimate transmitter, legitimate receiver, and eavesdropper are equipped with a single antenna. By considering various initial positions of the relay, we obtain the statistical knowledge of the received signal-to-noise ratio over $\alpha - \eta - k - \mu$ fading channel under vehicle mobility. Further, we derive an exact closed form expression for outage probability and secrecy outage probability utilizing the amplify-and-forward relay protocol for a two-lane high way scenario. Monte-Carlo simulations are performed to validate the accuracy of the derived analytical expressions.
