In recent times, spectrum sensing and spectrum management become a crucial design
issue in cognitive radio networks (CRN). To improve the spectrum utilization in CRN, the …

In this paper, the secrecy performance of a hybrid satellite-Underwater Optical
Communication (UWOC) system in the presence of an Unmanned Aerial Vehicle (UAV) …

In this paper, the secrecy outage performance is studied for optimal relay selection (ORS)
schemes with energy harvesting system deployed at the secondary transmitter to improve …

This work studies the physical layer security performance for Multiple Input Multiple Output
(MIMO) secondary nodes. The proposed model is assumed to operate in underlay Cognitive …

This paper introduces underlay multiple input multiple output (MIMO) cooperative
communication involving source, destination, eavesdropper, primary nodes and decode and …

In this article, we investigate physical layer security in downlink Internet of Things networks
under imperfect channel state information (CSI), in which a controller (Alice) intends to serve …

In this paper, we study an underlay Cognitive Radio (CR) system with energy harvesting
over Nakagami-m fading channel. This system consists of a secondary source, a secondary …

In this paper, the physical layer secrecy outage performance of Multiple Input Multiple Output
