Virtual network advance reservation
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Network virtualization provides a promising means of hosting multiple client infrastructures over a physical substrate. Now one of the key concerns here is how to map virtual network requests onto physical nodes and links, ...
Fractional low order cyclostationary-based spectrum sensing in cognitive radio networks
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, we study the problem of cyclostationary spectrum sensing in cognitive radio networks based on cyclic properties of linear modulations. For this purpose, we use fractional order of observations in cyclic ...
Efficient datacenter resource utilization through cloud resource overcommitment
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
We propose an efficient resource allocation framework for overcommitted clouds that makes great energy savings by 1) minimizing PM overloads via resource usage prediction, and 2) reducing the number of active PMs via ...
Distributed fair spectrum assignment for large-scale wireless DSA networks
(
Springer Verlag
, 2015 , Conference Paper)
This paper proposes a distributed and fair resource allocation scheme for large-scale wireless dynamic spectrum access networks based on particle filtering theory. We introduce a proportionally fair global objective function ...
The impact of authentic complex engineering design experience for k-12 students on 21st century attributes and perceptions towards STEM fields (Evaluation, Strand 3)
(
American Society for Engineering Education
, 2015 , Conference Paper)
Recent studies showed that embedding engineering at K-12 level has a positive impact on stimulating interest in- and improving learning outcomes of science and mathematics, and development of 21st Century skills. Engineering ...
Optimization of collaborative spectrum sensing with limited time resource
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, Cognitive Radios (CRs) collaborate in spectrum sensing to detect random signals corrupted by Gaussian noise. Our analysis is based on a limited time resource assumption. This implies that the time resource ...
A novel mechanism for restoring actor connected coverage in wireless sensor and actor networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Provisioning network survivability is especially crucial in wireless sensor and actor network (WSAN) because nodes deployed in hostile environments are prone to frequent failures. Failure of an actor significantly impact ...
Enhancement of the extracted maximum power of PV array during partial shading using switched PV-based system
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper proposes a switched PV approach to enhance the extracted maximum power from PV array during partial shading condition. The proposed system is simple and cost effective. However, it may provide lower power ...
Simple voltage regulation method for smart grid applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The complexity of power systems and the change of demand load at the consumer make it necessary to control the voltage to avoid any unnecessary voltage drop beyond the limits allowed within the international standards and ...
SFET-based multiple antenna spectrum sensing using the second order moments of eigenvalues
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose a new detector for multiantenna spectrum sensing in cognitive radios (CR) by exploiting the Separating Function Estimation Test (SFET) framework. Specifically, we consider a blind scenario for ...
