Secure Wireless Multicasting with Mixture Gamma Distribution for Generalized-K Fading Channels

This paper concentrates on the analysis of security performance for transmitting confidential data from a source to multiple receivers over Generalized-K fading multicasting channel in the presence of multiple eavesdroppers. All the terminals are equipped with single antenna and all the channels are Generalized-K fading based on mixture gamma distribution. In order to investigate the effects of fading parameters imposed on the Generalized-K fading with mixture gamma distribution, we derive the closed-form analytical expressions for the probability of non-zero secrecy multicast capacity, ergodic secrecy multicast capacity and the secure outage probability for multicasting &. The derived analytical expressions are presented in terms of the fading parameters of Generalized-K fading with mixture gamma distribution so that they are helpful to understand the insight, how the security in multicasting can be enhanced adjusting the parameters of Generalized-K fading channels. Monte-Carlo Simulations have also been performed to validate the analytical results.
