Physical Layer Security in UAV Systems: Challenges and Opportunities
Xiaofang Sun, Derrick Wing Kwan Ng, Zhiguo Ding +2
Unmanned aerial vehicle (UAV) wireless communications have experienced an upsurge of interest in both military and civilian applications, due to its high mobility, low cost, on-dem…
Analytical Modeling of UAV-to-Vehicle Propagation Channels in Built-Up Areas
Zhuangzhuang Cui, Ke Guan, César Briso +4
This letter presents an analytical path loss model for air-ground (AG) propagation between unmanned aerial vehicles (UAVs) and ground-based vehicles. We consider built-up areas, su…
Probabilistic Two-Ray Model for Air-to-Air Channel in Built-Up Areas
Zhuangzhuang Cui, Ke Guan, César Briso +3
In this paper, we present a probabilistic two-ray (PTR) path loss model for air-to-air (AA) propagation channel in built-up areas. Based on the statistical model of city deployment…
Throughput Maximization in Two-hop DF Multiple-Relay Network with Simultaneous Wireless Information and Power Transfer
Qi Gu, Gongpu Wang, Rongfei Fan +2
This paper investigates the end-to-end throughput maximization problem for a two-hop multiple-relay network, with relays powered by simultaneous wireless information and power tran…
Robust Trajectory and Resource Allocation Design for Secure UAV-aided Communications
Xiaofang Sun, Chao Shen, Derrick Wing Kwan Ng +1
This paper aims to enhance the physical layer security against potential internal eavesdroppings by exploiting the maneuverability of an unmanned aerial vehicle (UAV). We consider…
Resource Allocation for Device-to-Device Communications in Multi-Cell Multi-Band Heterogeneous Cellular Networks
Yali Chen, Bo Ai, Yong Niu +3
Heterogeneous cellular networks (HCNs) with millimeter wave (mm-wave) communications are considered as a promising technology for the fifth generation mobile networks. Mm-wave has…
