  • Harte, Seán; O'Flynn, Brendan; Martínez-Català, Rafael V.; Popovici, Emanuel M. (IEEE, 2008)
    Two complementary wireless sensor nodes for building two-tiered heterogeneous networks are presented. A larger node with a 25 mm by 25 mm size acts as the backbone of the network, and can handle complex data processing. A ...
  • Zheng, Liqiang; Mathewson, Alan; O'Flynn, Brendan; Hayes, Michael; Ó Mathúna, S. Cian (Editura Universitatii de Nord, 2010)
    Wireless sensor network (WSN) node, typically equipped with a radio transceiver, a small microcontroller and a battery, is different from traditional embedded systems because of its requirement of random deployment, small ...
  • Wang, Wensi S.; O'Donnell, Terence; Wang, Ningning; Hayes, Michael; O'Flynn, Brendan; Ó Mathúna, S. Cian (ACM, 2010-06)
    For most wireless sensor networks, one common and major bottleneck is the limited battery lifetime. The frequent maintenance efforts associated with battery replacement significantly increase the system operational and ...
  • O'Flynn, Brendan; Jafer, Essa; Špinar, Rostislav; Keane, Marcus M.; Ó Mathúna, S. Cian (2010-09)
    Buildings consume 40% of Ireland's total annual energy translating to 3.5 billion (2004). The EPBD directive (effective January 2003) places an onus on all member states to rate the energy performance of all buildings in ...
  • Zheng, Liqiang; Mathewson, Alan; O'Flynn, Brendan; Hayes, Michael; Ó Mathúna, S. Cian (IEEE, 2010-12)
    In this paper, the embedded capacitance material (ECM) is fabricated between the power and ground layers of the wireless sensor nodes, forming an integrated capacitance to replace the large amount of decoupling capacitors ...
  • Boyle, David; Magno, Michele; O'Flynn, Brendan; Brunelli, Davide; Popovici, Emanuel M.; Benini, Luca (IEEE, 2011-12-09)
    This paper documents the design, implementation and characterisation of a wireless sensor node (GENESI Node v1.0), applicable to long-term structural health monitoring. Presented is a three layer abstraction of the ...
