EHONs (Energy Harvesting Overlay Networks) satisfy stringent design requirements such as high energy-and-spectrum utilization efficiencies. However, due to open access nature of these networks, eavesdroppers can emulate cognitive radios to wire-tap l

Overlay mechanism offers secondary users (SUs) chances to access licensed spectrum of primary users (PUs) to improve spectrum utilization efficiency. However, these chances impose serious security challenges when wire-tappers emulate legal users (SUs

In cognitive radio networks, direct communications between a primary sender–recipient pair may be blocked due to uncertainties such as deep fading. Therefore, this paper studies overlay networks where the message of the primary sender is relayed by

This paper investigates a cognitive radio network where a secondary sender assists a primarytransmitter in relaying primary information to a primary receiver and also transmits its own information toa secondary recipient. This sender is capable of ja

We introduce a relay selection strategy to secure energy scavenging-based cognitive networks. The introduced strategy selects a relay which satisfies two conditions: i) decode correctly data of secondary source and ii) obtain the highest secrecy capa

The spectrum sharing paradigm is a promising countermeasure to the spectrum under-utilization problem. However, it causes both primary interference (inflicted by primary transmitters upon secondary receivers) and secondary interference (inflicted by

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 se
