abstract: Although cognitive radio networks (CRNs) were
originally intended as a powerful solution to enhance spectrum
utilization, it can also be used to improve reliability by avoiding
interference in the 2.4 or 5 GHz band. Using multiple relay nodes
in CRNs, the outage probability, i.e., the probability that the endto-end signal-to-noise ratio drops below a predefined threshold,
can be reduced significantly. This implies that the probability
that a message is not delivered within a specific time frame,
can be kept below a required threshold, even when there are
constraints on energy efficiency in terms of peak transmit power.
This is particularly useful for industrial networks with realtime constraints. However, using CRNs may also reveal secret
information to eavesdroppers (EAVs). Therefore, guaranteeing
secure and reliable communications in CRNs is still a challenging
problem. To this end, the secrecy performance of a proactive
decode-and-forward relaying scheme in a cognitive cooperative
radio network is investigated. More specifically, analytical as well
as approximate expressions for the secrecy outage probability and
probability of non-zero secrecy capacity are derived to evaluate
the system performance. Numerical results show that the approximation tightly match the analytical results and simulations,
and thus it can be used to provide a fast evaluation of the
security and reliability of communications using a considered
assignment of relay nodes in a cognitive cooperative radio
network (CCRN). Consequently, our results enable to secure
the communication, and increasing the reliability, availability,
robustness, and maintainability of wireless industrial network,
subject to various constraints from the CRN
