Friendly-Jamming: An anti-eavesdropping scheme in wireless networks

This paper proposes a novel anti-eavesdropping scheme by introducing artificial noise caused by friendly jammers deployed in wireless networks. In particular, we propose an analytical model to quantify the eavesdropping risk of wireless network with friendly jammers. Our approach considers both large-scale path loss and Rayleigh fading. Our numerical results show that the eavesdropping risk of wireless networks can be significantly reduced with the aid of firendly jammers.
