PHY layer security for IOT in κ-μ fading channel

Abstract

In this paper, we analyze the secrecy performance of a two hop communication system with a Decode-and-Forward (DF) relay in a k-μ fading channel for Internet of Things (IOT) applications in the presence of an eavesdropper. The eavesdropper wiretaps from a single hop in the first case and from both the hops in second case. Analytical expressions for Secrecy Outage Probability (SOP) and Strictly Positive Secrecy Capacity (SPSC) have been derived. MATLAB based simulation has been carried out to evaluate the secrecy performance following our analytical formulation. Effects of channel and network parameters on secrecy performance are indicated.
