Cognitive relaying in wireless sensor networks: Performance analysis and optimization
(
IEEE
, 2010 , Conference Paper)
The anticipated increase in the density of the deployed wireless sensor networks calls for spectrum sharing through unlicensed access to licensed spectrum. The key technology for spectrum sharing in this scenario is cognitive ...
Mobile wireless sensor networks applied to the survey of water infrastructures
(
IEEE
, 2010 , Conference Paper)
The paper reports our last advances in the realization of mobile wireless sensor networks (WSNs), able to reveal unknown tracks and leakages within underground pipelines used to distribute water. This WSN technology is ...
Optimization of probability of error in collaborative spectrum sensing of time-limited cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time resources in cognitive radio (CR) networks. The frame structures for sensing and data transmission, if the ...
Arabic handwriting recognition using sequential minimal optimization
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Due to the variability of writing styles and to other problems related to the nature of Arabic scripts, the recognition of Arabic handwriting is still awaiting accurate results. Segmentation of Arabic handwritten words ...
Vibration suppression in metastructures using zigzag inserts optimized by genetic algorithms
(
Springer New York LLC
, 2017 , Conference Paper)
Metastructures are known to provide considerable vibration attenuation for mechanical systems. With the optimization of the internal geometry of metastructures, the suppression performance of the host structure increases. ...
Optimal DC voltage control in multi-terminal HVDC Network: Modeling and scenarios
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Efficient and balanced power transfer with minimum transmission losses in Multi-Terminal High-Voltage DC (MTDC) network is managed by the hierarchical control layers. A combination of decentralized DC voltage droop control ...
Energy-aware cross-layer optimization for EEG-based wireless monitoring applications
(
IEEE Computer Society
, 2013 , Conference Paper)
Body Area Sensor Networks (BASNs) for healthcare applications have gained significant research interests recently due to the growing number of patients with chronic diseases requiring constant monitoring. Because of the ...
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 ...
Qualitative economic model for long-term IaaS composition
(
Springer Verlag
, 2016 , Conference Paper)
We propose a new qualitative economic model based optimization approach to compose an optimal set of infrastructure service requests over a long-term period. The economic model is represented as a temporal CP-Net to capture ...
Outage optimal resource allocation for two-hop multiuser multirelay cooperative communication in OFDMA upstream
(
IEEE
, 2011 , Conference Paper)
We investigate an outage optimal adaptive resource allocation scheme for the upstream of two-hop OFDMA based decode-and-forward cooperative relay systems. The objective of this work is to design resource allocation strategy, ...
