Physical Layer Security in Two-tier Heterogeneous Cellular Networks over Nakagami Channel during Uplink Phase
In this paper, we study the connection and secrecy performance under two-tier cellular network during uplink phase, where both large-scale factor (path propagation loss) and small-scale factor (Nakagami fading) are considered., which are beyond the scope of the existing works. Analytical expressions of network connection and secrecy probabilities are derived., which are validated through Monte Carlo simulations. Numerical results reveal that the theoretical expressions of connection and secrecy probabilities are in good agreement with simulation results. Moreover, simulation results demonstrate that larger $m$ value, which means stronger LOS component, leads to a worse connection performance, but a better secrecy secrecy performance.
This paper studies the secure multiterminal source coding problem with actions. In particular, one main encoder observes an independent and identically distributed (i.i.d.) source Xn and wishes to compress this source lossyly to the decoder. Another encoder observes the source Yn and wants to compress this source losslessly to the decoder. A passive eavesdropper having access to the side information Zn can observe the information bits sent by the main encoder. In this scenario, the decoder is allowed to choose actions affecting the correlated source Yn and the side information Zn. For this problem, we characterize the optimal rate-distortion-cost-leakage region for a discrete memoryless setting.
