Enhancing Security in Multicasting Over Nakagami-0.5 Fading Channel with Selection Combining Schemes

The effect of Selection Combining scheme is focusing on the enhancing security in multicasting over Nakagami 0.5 fading channel in the presence of multiple eavesdroppers. The study explores a scenario where a single-antenna transmitter communicates with multiple destinations and multiple eavesdroppers are trying to decode that confidential information. The closed-form analytical expressions are derived for the probability of non-zero secrecy multicast capacity and the secure outage probability for multicasting. These expressions shed light on the impact of key system parameters, such as the number of receivers, the number of eavesdroppers and the number of antennas at the receiver and eavesdropper. In order to enhance the communication security, the study employs linear diversity combining schemes such as Selection Combining, Maximal Ratio Combining and Equal Gain Combining diversity schemes. By leveraging these advanced techniques, the research contributes valuable insights to enhance the security of multicast communications systems employing the benefits of aforementioned diversity combining schemes with Nakagami 0.5 fading channel.
