Security in Wireless Multicast Networks with Exponential Correlation over Nakagami-m Fading Channels

Abstract

In this paper, we consider the problem of transmission of sensitive message in wireless multicast cellular network through identically distributed Nakagami-m fading multiple-input multiple-output (MIMO) channels considering the existence of multiple eavesdroppers. It is assumed that the antennas in the destinations and eavesdroppers are exponentially correlated. Considering channel state information (CSI) at the receiver, the closed-form analytical expressions for the ergodic secrecy multicast capacity (ESMC) and the probability of non zero secrecy multicast capacity (PNSMC) have been derived to investigate the effect of correlation and fading parameter on the proposed model. Numerical results of the derived analytical expressions are presented and demonstrated using Monte-Carlo simulation.
