Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks
(
Springer International Publishing
, 2016 , Article)
In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to ...
Relay selection in FDD amplify-and-forward cooperative networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
In this paper, the problems of relay selection and distributed beamforming are investigated for bi-directional dual-hop amplify-and-forward frequency-division duplex cooperative wireless networks. When using individual ...
Exploiting Traffic Correlation Towards Energy Saving in Data Centers
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Many proposed data center architectures are constructed with a huge number of network devices in order to support the increasing cloud based services. These devices are used to achieve the highest performance in case of ...
Sparsity-aware narrowband interference mitigation and subcarriers selection in OFDM-based cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, the performance of an orthogonal frequency division multiplexing overlay cognitive radio network with subcarrier selection schemes is investigated. We propose three subcarrier selection techniques that reduce ...
A sparsity-aware approach for NBI estimation and mitigation in large cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the coverage area. Therefore, in this ...
Secondary users selection and sparse narrow-band interference mitigation in cognitive radio networks
(
Elsevier B.V.
, 2018 , Article)
Spectrum scarcity is a critical problem that may reduce the effectiveness of wireless technologies and services. To address this problem, different spectrum management techniques have been proposed in the literature such ...
Sparsity-Aware multiple relay selection in large dual-hop decode-And-forward broadband relay networks
(
IEEE
, 2016 , Conference Paper)
In this paper, three novel techniques are proposed and investigated for multiple relay selection in dual hop OFDM networks. These techniques are based on the exploitation of sparse signal recovery theory and on carefully-designed ...
Efficient techniques for energy saving in data center networks
(
Elsevier B.V.
, 2018 , Article)
Data centers are constructed with a huge number of network devices to support the expanding cloud based services. These devices are used to achieve the highest performance in case of full utilization of the network. However, ...
