Opportunistic Jamming for Enhancing Security:Stochastic Geometry Modeling and Analysis
Published in IEEE Transactions on Vehicular Technology, 2016
Abstract: This paper studies the secrecy communication of the single-input-single-output multieavesdropper (SISOME) channel with multiple single-antenna jammers, where the jammers and the eavesdroppers are distributed according to the independent 2-D homogeneous Poisson point process (PPP). For enhancing the physical layer security, we propose an opportunistic multiple-jammer selection scheme, where the jammers whose channel gains to the legitimate receiver are less than a threshold are selected to transmit independent and identically distributed (i.i.d.) Gaussian jamming signals to confound the eavesdroppers. We characterize the secrecy throughput achieved by our proposed jammer selection scheme and show that the secrecy throughput is a quasi-concave function of the selection threshold.
