3-D Placement Schemes of Multiple UAVs in NFP-based Wireless Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
In this paper, we propose two placement strategies of multiple unmanned aerial vehicles (UAVs) in network flying platform (NFP)-based wireless networks. The first strategy is based on a proposed distributed placement ...
A Distance-Based Mode Selection Scheme for D2D-Enabled Networks with Mobility
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, a new mode selection scheme for device-to-device (D2D)-enabled cellular communications with mobility is proposed and evaluated. The new scheme is based on an average threshold D2D distance between two given ...
Physical Layer Security Analysis of UAV Based Communication Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
In this paper, we investigate the communication security in aerial wiretap channels, where a network flying platform (NFP) wishes to send information to a legitimate destination, in the presence of multiple eavesdroppers. ...
Average Secrecy Outage Rate and Average Secrecy Outage Duration of Wireless Communication Systems with Diversity over Nakagami-m Fading Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
This paper presents an analytical methodology for the evaluation of two important physical layer security metrics in wiretap channels. Specifically, we first introduce the concept and the expression of average secrecy ...
Enhancing wireless networks performance through cooperative communications with interference management
