Artificial Noise Aided Polar Code with Optimal Jamming Position for Physical Layer Security in Mondrian Loss Integrated Rayleigh Wireless Relay Channel
V N Senthil Kumaran
This research article introduces a Dragonfly Water Cycle Algorithm (DWCA) to inject Artificial Noise (AN) into the codeword. The proposed DWCA integrates the Dragonfly Algorithm (DA) and Water Cycle Algorithm (WCA). The noise is injected at the last transmission block of confidential bits. Knowing the position of confidential bits and jamming position, where the noise is being added, only legitimate receiver can decode the confidential information accurately from the transmitter. The eavesdropper does not know the jamming position and confidential bits because information is completely jammed. Hence, the eavesdropper is confused regarding the transmitted signal. The proposed method achieved a lower Bit Error Rate (BER) of 3 and a higher secrecy capacity 7.57×10-6, the minimal block error rate of 0.20, and the maximal throughput of 3.68.
Keywords: Artificial Noise (AN), polar codes, jamming position, physical layer security, Dragonfly Algorithm (DA), Water Cycle Algorithm (WCA)
