| Popis: | An unlicensed relay is located between an unlicensed sender and an unlicensed recipient for securing the sender’s message against a wire-tapper in underlay cognitive networks when the sender–recipient channel is inaccessible. The energy in the sender’s signals is harvested by the relay which utilizes that harvested energy for its signal transmission. To assess expeditiously the security capability, a precise formula of secrecy outage probability is suggested. This formula is then substantiated by computer simulations. Notably, the appropriate selection of system specifications including the time percentage, the relay’s location, the power percentage can drastically enhance the security capability of underlay cognitive relaying networks with energy harvesting. Also, the security capability is constant when one of two power curtailments of unlicensed senders (interference power curtailment and peak transmit power curtailment) is relaxed. |
