In this paper, we consider a cooperative multi-hop secured transmission protocol to underlay
cognitive radio networks. In the proposed protocol, a secondary source attempts to transmit …

… In this paper, we propose three path selection methods for cluster-based cognitive radio (CR)
networks for secrecy enhancement by formulating the probability of non-zero secrecy …

… network and the constraints on secrecy due to the presences of an eavesdropper. Next,
we analyze the secrecy performance of the CCRN based on these power allocation policies. …

… level of secrecy. In this paper, we consider the additional secrecy enhancement with artificial
noise and secrecy … Specifically, we derive the secrecy transmission rate and investigate the …

… the open broadcast nature of their communication. This paper investigates the improvement
of secrecy performance in random-access-based WMB (RA-WMB) networks by integrating …

… , we investigate the secrecy performance of the proposed network in the Rayleigh fading …
for the secrecy outage probability, intercept probability, and -outage secrecy capacity in a …

… (MISOME) primary network co-existing with a multiple-input single-output (MISO) SU pair.
The SU can get the transmission opportunity by enhancing the secrecy of the primary …

… This can increase the secrecy performance of the cellular networks by reducing the signal
strength … on the performance increase that the RIS can achieve because it is an ideal situation. …

… security of primary networks and investigate the impact of interference temperature I and
transmit peak power PS on the secrecy performance, we use ergodic secrecy rate (ESR) as the …

… To investigate the secrecy performance of the SU further, we first consider the following
random variable (37) Z = 1 + γ SU 1 + γ e 2 , The CDF of Z can be derived as follows (38) F Z ( z ) …
