Ad hoc innovation: distributed decision making in ad hoc networks
DOYLE, LINDA; FORDE, TIM; O'MAHONY, DONAL EDWARD (IEEE, 2006)Mobile ad hoc networks by their nature are highly adaptive systems that can come into existence on an as needed basis. They can grow, reduce in size, fragment, and dismantle as desired. The dynamic and very flexible nature ... -
Ad hoc Networking, Markov Random Fields, and Decision Making
DOYLE, SENAN; DOYLE, LINDA; FORDE, TIM; KOKARAM, ANIL CHRISTOPHER (2006)Our central proposition is that by articulating decision making in an ad hoc network using a Markov random field (MRF) maximum a posteriori (MAP) approach, a viable decision- making framework can be designed. This ... -
Analysing the security threats against network convergence architectures
ARGYROUDIS, PATROKLOS; DOYLE, LINDA; O'MAHONY, DONAL EDWARD (IEEE Computer Society Press, 2007)Current research trends in networks and telecommunications suggest that future architectures will aim for the convergence not only of fixed and mobile infrastructures, but also of different network layer technologies. ... -
Architectural imperatives for 4th generation IP-based mobile networks
DOYLE, LINDA; O'MAHONY, DONAL EDWARD (2001) -
Architectures for person to person communications in disaggregated networks
ARGYROUDIS, PATROKLOS; DOYLE, LINDA; O'MAHONY, DONAL EDWARD (IEEE, 2006)Current telecommunications systems allocate identifiers to devices, and end-points. While this has worked well thus far, we believe that as more devices are used to access these systems, people have a tendency to be mobile ... -
Bandwidth-adaptive waveforms for dynamic spectrum access networks
DOYLE, LINDA; NOLAN, KEITH EDWARD; SUTTON, PAUL DAVID (IEEE, 2008)This paper presents a novel solution to the challenge of waveform bandwidth estimation in DySPAN systems using intentionally embedded cyclostationary signatures. Dynamic spectrum access networks (DySPANs) achieve high ... -
Cognitive Radio: Ten Years of Experimentation and Development
NOLAN, KEITH EDWARD; DOYLE, LINDA (2011) -
Cognitive radio: value creation and value migration
DOYLE, LINDA; NOLAN, KEITH EDWARD; O'MAHONY, DONAL EDWARD; Ambrose, E. (2006)This paper develops the concept of a telecommunications value-chain and explores the many ways in which the valuechain can be altered by reconfigurable software-defined radios, cognitive radios and cognitive networks. ... -
Combinatorial clock auction for OFDMA-based cognitive wireless networks
DOYLE, LINDA; FORDE, TIM (IEEE, 2008)This paper presents a novel application of a market-based spectrum assignment mechanism for exploitation by cognitive radio systems. Advances in DSA policy mean that regulators are moving towards a more liberalised ... -
A Combinatorial Optimisation Approach to the Design of Dual Parented Long-Reach Passive Optical Networks
RUFFINI, MARCO; PAYNE, DAVID; DOYLE, LINDA (2011)We present an application focused on the design of resilient long-reach passive optical networks. We speci?cally consider dual parented networks whereby each customer must be connected to two metro sites via a local exchange ... -

A cost analysis of optical IP switching in new generation optical networks
DOYLE, LINDA; O'MAHONY, DONAL EDWARD; Ruffini, M. (IEEE, 2006)In this paper we propose a simple model that analyzes the cost saving achieved by optical IP switching (OIS), a novel optical architecture, compared to a conventional IP-over-WDM network, where the IP router connects ... -
Cost study of dynamically transparent networks
DOYLE, LINDA; O'MAHONY, DONAL EDWARD (Optical Society of America, 2008)The network equipment cost benefit of dynamic wavelength routing is compared with point-to-point IP networks and static wavelength routing in a simple ring topology with variable network traffic loading. -
Customized Services over Virtual Wireless Networks: The Path towards Networks without Borders
DA SILVA, LUIZ; DI FRANCESCO, PAOLO; DOYLE, LINDA; FORDE, TIM (2013)We propose a new architecture to enable wireless networks to meet th e challenges of ever - increasing demand for high data rate services and ubiquitous connectivity, heterogeneity of access technologies, and spectrum ... -
Cyclostationary signatures for LTE Advanced and beyond
DOYLE, LINDA; SUTTON, PAUL (2014)Long Term Evolution (LTE) Advanced is the next generation of the LTE standard, offering peak data rates of up to 1 Gbps using up to 100 MHz of spectrum. A key mechanism in achieving this is carrier aggregation (CA) whereby ... -
Cyclostationary signatures for rendezvous in OFDM-based dynamic spectrum access networks
DOYLE, LINDA; NOLAN, KEITH EDWARD; SUTTON, PAUL DAVID (IEEE, 2007)Abstract?Distributed coordination of operating frequencies and bandwidths is one of the key challenges in the development of dynamic spectrum access (DSA) technology. The spectrum efficiency of DSA networks is achieved ... -
Cyclostationary signatures in practical cognitive radio applications
DOYLE, LINDA; NOLAN, KEITH EDWARD; SUTTON, PAUL DAVID (IEEE, 2008)We define a cyclostationary signature as a feature which may be intentionally embedded in a digital communications signal, detected through cyclostationary analysis and used as a unique identifier. The purpose of this paper ... -
