… networks. This work considers a cognitive relay network where UAV is used as a mobile
relay to … Our purpose is to maximize the secrecy rate under certain UAV trajectory and power …

… Here we employ modified interference constraints at the source that (as we will show later)
enables us to improve secrecy performance. With the ITL IP chosen to guarantee outage QoS …

… Dongqing Xie et al. analyzed the performance of the underlying cognitive energy harvesting
and relay network system with line-of-sight (LoS) path [8]. Chi Xu studied the PU transmitter …
