Secure outage performance analysis of wireless multicasting through Weibull fading channel

Abstract

In this paper, we consider the transmission of confidential message through Weibull fading single-input single-output (SISO) channel in the presence of multiple eavesdroppers. At first, we define perfect secrecy capacity in terms of secure outage probability and provide a complete characterization of the maximum transmission rate at which the eavesdroppers are unable to decode any information. Then, we find the average secrecy capacity for multicasting in the presence of multiple eavesdroppers. Finally, we find the closed-form expression for the secure outage probability to investigate the secure outage performance of Weibull fading SISO channel in the presence of multiple eavesdroppers and simulated ergodic secrecy multicast capacity for different fading parameters to observe the effect of diversity on the fading parameter.
