Abstract

We study the physical-layer security of multi-hop secondary network under spectrum sharing constraint caused by the primary, which consists of many simultaneously independent direct transceiver pairs. The existence of a secondary eavesdropper, which attempts to hear confidential information, results in secure communication to be needful. The PUs’ interference forces low secondary SIRs. The secondary power constraint according to PUs causes the QoS to diminish, especially when the PUs transmission simultaneously operates. In this paper, we derive the closed-form of end-to-end multi-hop secrecy outage probability expression with independent non-identically distributed (i.n.i.d) Rayleigh fading. Furthermore, the secondary intercept probability is derived. Combining the outage probability, we present the security-reliability of the system. Besides, the impact of different numbers of primary transceivers on end-to-end multi-hop outage probability is investigated. Finally, our theoretical results verified via extensive Monte Carlo simulations.
