The Virtual DBA: Virtualizing Passive Optical Networks to Enable Multi-Service Operation in True Multi-Tenant Environments
(2020)This paper presents the concept of virtual dynamic bandwidth allocation (DBA), a method we propose to virtualize upstream capacity scheduling in passive optical networks (PONs), which provides multiple independent virtual ... -
3-stage Hierarchical Quality of Service for Multi-tenant Passive Optical Network
(2019)Passive Optical Networks (PONs) are an economically efficient means of providing high bandwidth services to end users. This is because PONs are multi-point shared access medium, where end-points can share the cost ... -
Joint Dynamic Bandwidth and Queue Management for Upstream SLA-Oriented QoS in Multi-Tenant, Multi-Service PONs
(2020)We devise a PON upstream scheduler that jointly manages intra-ONT and inter-ONT capacity across VNOs. This provides balancing between throughput and delay, providing SLA-oriented QoS supporting low latency 5G applications ... -
A Performance Analysis of Supervised Learning Classifiers for QoT Estimation in ROADM-based Networks
(2019)Machine learning techniques for optimization purposes in the optical domain have been reviewed extensively in recent years. While several studies are pointing in the right direction towards building ... -
Evolution of access network sharing towards software based passive optical network: can virtual OLTs run at full line rate?
(2020)This paper summarises how access network sharing has evolved from physical layer unbundling to fully virtualised architectures. We address one of the crucial question in access network virtualisation: whether fully virtualised ... -
Virtualised EAST-WEST PON Architecture Supporting Low-Latency communication for Mobile Functional-Split Based on Multi-Access Edge Computing
(2020)Ultralow latency end-to-end communication with high reliability is one of the most important requirements in 5G networks to support latency-critical applications. A recent approach toward this target is to deploy edge ... -
A Silicon Photonic Switching Platform for Flexible Converged Centralized-Radio Access Networking
(2020)Unprecedented levels of device connectivity and the emergence of futuristic digital services are driving fundamental changes to underlying fixed and wireless data transport networks. Projected ... -
Sharing Distributed and Heterogeneous Resources toward End-to-End 5G networks: A Comprehensive Survey and a Taxonomy
(2020)Regardless of the context to which it is applied,sharing resources is well-recognized for its considerable benefits.Since 5G networks will be service-oriented, on-demand, and highly heterogeneous, it is ... -
Issues Relating to Trust in Care Agents for the Elderly
(ACM, 2019-08-22)There is increasing academic interest in and commercial development of care agents to assist with the care of the elderly in the home. This paper defines some of the under-explored questions and issues relating to trust. ... -
What makes a good conversation? Challenges in designing truly conversational agents
(ACM, 2019-05)Conversational agents promise conversational interaction but fail to deliver. Efforts often emulate functional rules from human speech, without considering key characteristics that conversation must encapsulate. Given its ... -
ADELE: Evaluating and Benchmarking an Artificial Conversational Care Agent
(http://casforhealth.org, 2020-04-26)This paper provides an overview of a planned experiment to evaluate the latest iteration of ADELE, an artificial conversational agent to aid in the care of the elderly. It is being evaluated against an earlier iteration ... -
The Impact of Increasing and Decreasing the Professionalism of News Webpage Aesthetics on the Perception of Bias in News Articles
(Springer, 2020-07-19)This paper reports further results from a large study examining the impact of the visual aesthetics of news websites on the perception of bias in news articles. It focuses on the characteristic of professionalism, which ... -
A Classification of Biases Relating to the Production, Dissemination and Consumption of News
(http://critical-media.org/, 2020-04-25)There are many difficulties in studying bias at the production, dissemination, or consumption stages of the news pipeline. These include the difficulty of identifying high quality empirical research, the lack of agreed ... -
Tabloidization versus Credibility: Short Term Gain for Long Term Pain
(ACM, 2020)Print news agencies have been under pressure from falling sales and advertising revenue and increased competition. As the Internet became the dominant medium, news agencies invested heavily in their websites and apps, ... -
Nouns and Verbs in Professional Reporting of Extreme Events
(2019)This corpus-based study tested whether linguistic devices that can evoke negative emotions are featured in Terrorist Attack news articles to a greater extent, in comparison to articles on Natural Disasters and Human ... -
Linguistic and Behaviour Interaction Analysis within Cognitive Infocommunications
(2019)Cognitive infocommunications is a discipline that examines the extensions of human cognitive capabilities that are assimilated within the concept of humanity. We argue that necessary (but not sufficient) conditions for the ... -
Advancing and Validating Models of Cognitive Architecture
(2019)We present a methodology for proposing and evaluating components of cognitive architectures comprising complementary approaches: hypothesizing and behavioral mechanisms, evaluating the aptness of those mechanisms in providing ... -
Personalization of Infectious Disease Risk Prediction: Towards Automatic Generation of a Bayesian Network
(IEEE Computer Society, 2017)Infectious diseases are a major cause of human morbidity, but most are avoidable. An accurate and personalized risk prediction is expected to alert people to the risk of getting exposed to infectious diseases. However, as ... -
The MULTISIMO multimodal corpus of collaborative interactions
(2017)This paper describes a recently created multimodal corpus that has been designed to address multiparty interaction modelling, specifically collaborative aspects in task-based group interactions. A set of human-human ... -
Implementation of PI2 Queuing Discipline for Classic TCP Traffic in ns-3
(International Fedaration for Information Processing, 2017)This paper presents the implementation and validation of PI2 Active Queue Management (AQM) algorithm in ns-3. PI2 provides an alternate design and implementation to Propor- tional Integral controller Enhanced (PIE) algorithm ...
