In many applications of Internet of Things (IoT), the huge amount of data are generated by
sensor nodes and processing them are complex. Offloading data classification and anomaly …

In this paper, we consider an underlay multiple-input-multiple-output (MIMO) cognitive radio
network (CRN) including a pair of primary nodes, a couple of secondary nodes, and an …

We analyze a secure dual-hop mixed radio frequency-free space optical (RF-FSO) downlink
simultaneous wireless information and power transfer system. The FSO link and all RF links …

In this paper, directional modulation (DM) is investigated to enhance physical layer security.
Practical transmitter designs are exploited under imperfect channel state information (CSI) …

Wireless vehicular network (WVN) is exponentially gaining attention from industries and
researchers since it is the keystone of intelligent transportation systems (ITS). Despite the …

In this paper, the secrecy performance of single-input-multiple-output systems over
correlated κ-μ shadowed fading channels is investigated. In particular, based on the classic …

Free-space optical (FSO) links are contemplated as a potential paradigm to yield efficient
point-to-point communication in wireless systems. Notably, these links are used to provide …

In this paper, we consider a cooperative multi-hop secured transmission protocol to underlay
cognitive radio networks. In the proposed protocol, a secondary source attempts to transmit …

Energy-efficient and secure wireless communications have recently earned tremendous
interests due to economic, environmental, and military concerns. This paper investigates the …

In this paper, we analyze the secrecy performance of the decode-and-forward (DF) relay
system in generalized-K fading channels. In a typical four-node communications model, a …
