Abstract
Analysis of Probability of Non-zero Secrecy Capacity for Multi-hop Networks in Presence of Hardware Impairments over Nakagami-m Fading Channels
Highlights
Physical-layer security (PLS) has gained much attention as an efficient method to obtain the security in the presence of eavesdroppers, without using complex cryptographic methods [1]
We derive exact expressions of the probability of non-zero secrecy capacity (PoNSC) over Nakagami-m fading channels. These formulas are expressed by infinite series of exponential functions and exponential integral functions
Results presented that simulation and theoretical results are in good agreement when we truncate infinite series at first 100 terms
Summary
Physical-layer security (PLS) has gained much attention as an efficient method to obtain the security in the presence of eavesdroppers, without using complex cryptographic methods [1]. In [6] and [7], the authors evaluated the secrecy performances of the relaying networks at the second phase (cooperative phase). The authors in [7] investigated the impact of co-channel interference on the secrecy performance of various relay selection strategies. In [8] and [9], dual-hop secured communication protocols in one-way and two-way relaying networks were studied, respectively. The transceiver hardware is imperfect due to phase noises, amplifier-amplitude non-linearity and in phase and quadrature imbalance (IQI) [12], [13], which degrades performances of wireless relay networks. 4, DECEMBER 2016 crecy capacity (PoNSC) of a multi-hop transmission scheme, where the data transmitted from a source, via multiple relays, to a destination is overheard by an eavesdropper.
