Important complexity reduction of random forest in multi-classification problem
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Algorithm complexity in machine learning problems has been a real concern especially with large-scaled systems. By increasing data dimensionality, a particular emphasis is placed on designing computationally efficient ...
Multiple Relay Selection and Beamforming in Dual-Hop Amplify-and-Forward Relay Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this paper, the problems of multiple relay selection and beamforming optimization are considered for a dual-hop amplify-and-forward relaying network under individual and total power constraints. The selection is performed ...
Optimal Group Formation in Dense Wi-Fi Direct Networks for Content Distribution
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Wi-Fi Direct enables direct communication between Wi-Fi devices by forming Peer to Peer (P2P) groups. In each P2P group, one device becomes the Group Owner (GO) and serves as an access point (AP) to connect the remaining ...
Green data center networks: A holistic survey and design guidelines
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Data Center Networks (DCNs) are attracting immense interest from the industry, research and academia to keep pace with the increase of Internet services demands. One of the major concerns that draws the attention of ...
Security-Enhanced SC-FDMA Transmissions Using Temporal Artificial-Noise and Secret Key Aided Schemes
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
We investigate the physical-layer security of uplink single-carrier frequency-division multiple-access (SC-FDMA) systems. Multiple users, Alices, send confidential messages to a common legitimate base-station, Bob, in the ...
Time-Dependent Bit Error Rate Analysis for Smart Utility Networks in the Presence of WLAN Interferers
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
The smart grid (SG) modernizes the aging power grid by using two-way reliable communications dedicated to adaptive energy management. To achieve this goal, smart utility networks (SUNs) are used to efficiently connect the ...
A Novel UAV-Aided Network Architecture Using Wi-Fi Direct
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
The use of unmanned aerial vehicles (UAVs) in future wireless networks is gaining attention due to their quick deployment without requiring the existing infrastructure. Earlier studies on UAV-aided communication consider ...
Joint Frame Synchronization and Channel Estimation: Sparse Recovery Approach and USRP Implementation
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Correlation-based techniques used for frame synchronization can suffer significant performance degradation over multi-path frequency-selective channels. In this paper, we propose a joint frame synchronization and channel ...
On the delay/throughput-security tradeoff in wiretap TDMA networks with buffered nodes
(
IEEE
, 2019 , Article)
In this paper, we investigate the tradeoff between security and throughput and between security and queuing delay in wiretap time-division multiple access (TDMA) networks. We derive a simple relationship, characterized by ...
Exploiting Sparsity in Amplify-and-Forward Broadband Multiple Relay Selection
(
IEEE
, 2019 , Article)
Cooperative communication has attracted significant attention in the last decade due to its ability to increase the spatial diversity order with only single-antenna nodes. However, most of the techniques in the literature ...
