Partial relay selection in underlay cognitive networks with fixed gain relays
(
IEEE
, 2012 , Conference Paper)
In a communication system with multiple cooperative relays, selecting the best relay utilizes the available spectrum more efficiently. However, selective relaying poses a different problem in underlay cognitive networks ...
Innovative ad-hoc wireless sensor networks to significantly reduce leakages in underground water infrastructures
(
IEEE
, 2010 , Conference Paper)
This paper presents an ICT solution to overcome the problem of water dispersion in water distribution networks. Leakage prevention and breaks identification in water distribution networks are fundamental for an adequate ...
Contributions of competition based complex engineering design experience to leadership development in engineering students
(
American Society for Engineering Education
, 2015 , Conference Paper)
Engineering design activities provide students an opportunity to develop a number of skills. Engineering design experiences not only help students to acquire practical or technical skills, but also may enhance a number of ...
Performance analysis of relay selection schemes in underlay cognitive networks with imperfect channel state information
(
IEEE Computer Society
, 2013 , Conference Paper)
Cognitive Radio (CR) aims to improve spectrum utilization by allowing unlicensed users to access the licensed spectrum and to coexist with primary user (PU) while respecting the PU's restrictions. An interesting case to ...
Two way opportunistic MAC protocol for Ad Hoc networks
(
IEEE
, 2011 , Conference Paper)
In this paper, network coding is introduced in relay based MAC protocols for bidirectional traffic to evaluate the performance in terms of throughput and energy. The idea of proposed scheme is to use high data rate nodes ...
Skills of engineers in knowledge based economies: A comprehensive literature review, and model development
(
IEEE
, 2013 , Conference Paper)
Recent studies emphasize the needs of a wider set of skills engineers require than ever thought. In this paper, authors report on a systematic literature review on this issue. Findings of the review are spanned over two ...
Modelling, analysis and performance improvement of an SRU's access request queue in multi-channel V2I communications
(
Elsevier B.V.
, 2015 , Conference Paper)
This paper presents a concise yet comprehensive description of a multi-channel Vehicle-to-Infrastructure (V2I) communication system. Existing mathematical models for such a system overlook some of its essential behavioural ...
Adaptive network coding for spectrum sharing systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose an adaptive network coding scheme for cognitive relay networks comprising multiple secondary sources communicating with a common destination in the presence of multiple primary users. Conventional ...
Improved relay selection for decode-and-forward cooperative wireless networks under secrecy rate maximization
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Privacy and security have an increasingly important role in wireless networks. A secure communication enables a legitimate destination to successfully retrieve information sent by a source, while it disables the eavesdropper ...
Optimal power consumption based on new power spectral efficiency metric for wireless cellular networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we introduce a new power spectral efficiency (PSE) metric, to quantify the spectral efficiency and the total required power to cover a certain area with a predefined received signal quality. This metric ...
