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 ...
Advanced experimental setup for the reliability characterization of radio-acoustic sensors in water pipes
(
IEEE
, 2011 , Conference Paper)
The paper presents the design and construction of a test bench for the analysis and certification of radio-acoustic sensors inside conduits filled with liquids. It is a brand new test-set that integrates the capability to ...
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 ...
Priority-based scheduling for limited energy cognitive relaying
(
IEEE
, 2010 , Conference Paper)
We study the problem of cognitive relaying with limited-energy constraint in opportunistic spectrum access cognitive networks. Under this network setting, the cognitive user increases the spectrum availability for its own ...
Sequential random selection relaying for energy efficient wireless sensor networks
(
IEEE
, 2010 , Conference Paper)
In a wireless sensor network with relaying capability, intermediate relay nodes are with limited energy budget. To maximize lifetime of relay nodes, selective relay strategies, requiring full channel state information ...
Cognitive relay-sharing by using hierarchical modulation under interference constraints
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we investigate relay-sharing in cognitive radio (CR) networks to improve the secondary user's (SU's) performance in the presence of interference. It is assumed that the relay is shared simultaneously between ...
