The application of message-passing Graph Neural Networks has been a breakthrough for important network science problems. However, the competitive performance often relies on using…
On Optimal Battery Sizing for Electric Vehicles
Felix Wieberneit, Emanuele Crisostomi, Anthony Quinn +3
In this paper, we introduce a quantitative framework to optimize electric vehicle (EV) battery capacities, considering two criteria: upfront vehicle cost and charging inconvenience…
Tree Proof-of-Position Algorithms
Aida Manzano Kharman, Pietro Ferraro, Homayoun Hamedmoghadam +1
We present a novel class of proof-of-position algorithms: Tree-Proof-of-Position (T-PoP). This algorithm is decentralised, collaborative and can be computed in a privacy preserving…
Reinforcement Learning with Adaptive Regularization for Safe Control of Critical Systems
Haozhe Tian, Homayoun Hamedmoghadam, Robert Shorten +1
Reinforcement Learning (RL) is a powerful method for controlling dynamic systems, but its learning mechanism can lead to unpredictable actions that undermine the safety of critical…
Robust decentralised proof-of-position algorithms for smart city applications
Aida Manzano Kharman, Pietro Ferraro, Anthony Quinn +1
We present a decentralised class of algorithms called Tree-Proof-of-Position (T-PoP). T-PoP algorithms rely on the web of interconnected devices in a smart city to establish how li…
On Unique Ergodicity Of Coupled AIMD Flows
Pietro Ferraro, Jia Yuan Yu, Ramen Ghosh +4
The AIMD algorithm, which underpins the Transmission Control Protocol (TCP) for transporting data packets in communication networks, is perhaps the most successful control algorith…
Respiratory Aware Routing for Active Commuters
Abigail Langbridge, Pietro Ferraro, Robert Shorten
Cyclists travelling in urban areas are particularly at risk of harm from particulate emissions due to their increased breathing rate and proximity to vehicles. In this paper we com…
An adversarially robust data-market for spatial, crowd-sourced data
Aida Manzano Kharman, Christian Jursitzky, Quan Zhou +4
We describe an architecture for a decentralised data market for applications in which agents are incentivised to collaborate to crowd-source their data. The architecture is designe…
A DLT enabled smart mask system to enable social compliance
Lianna Zhao, Pietro Ferraro, Robert Shorten
As Covid-19 remains a cause of concern, especially due to its mutations, wearing masks correctly and efficiently remains a priority in order to limit the spread of the disease. In…
Feedback control for distributed ledgers: An attack mitigation policy for DAG-based DLTs
Pietro Ferraro, Andreas Penzkofer, Christopher King +1
In this paper we present a feedback approach to the design of an attack mitigation policy for DAG-based Distributed Ledgers. We develop a model to analyse the behaviour of the ledg…
Secure Access Control for DAG-based Distributed Ledgers
Lianna Zhao, Luigi Vigneri, Andrew Cullen +3
Access control is a fundamental component of the design of distributed ledgers, influencing many aspects of their design, such as fairness, efficiency, traditional notions of netwo…
On node ranking in graphs
Ekaterina Dudkina, Michelangelo Bin, Jane Breen +9
The ranking of nodes in a network according to their ``importance'' is a classic problem that has attracted the interest of different scientific communities in the last decades. Th…
Personalised Feedback Control, Social Contracts, and Compliance Strategies for Ensembles
Pietro Ferraro, Lianna Zhao, Christopher King +1
This paper describes the use of Distributed Ledger Technologies as a mean to enforce social contracts and to orchestrate the behaviour of agents in a smart city environment. Specif…
Kemeny-based testing for COVID-19
Serife Yilmaz, Ekaterina Dudkina, Michelangelo Bin +6
Testing, tracking and tracing abilities have been identified as pivotal in helping countries to safely reopen activities after the first wave of the COVID-19 virus. Contact tracing…
Access Control for Distributed Ledgers in the Internet of Things: A Networking Approach
Andrew Cullen, Pietro Ferraro, William Sanders +2
In the Internet of Things (IoT) domain, devices need a platform to transact seamlessly without a trusted intermediary. Although Distributed Ledger Technologies (DLTs) could provide…
Post-Lockdown Abatement of COVID-19 by Fast Periodic Switching
M. Bin, P. Cheung, E. Crisostomi +8
COVID-19 abatement strategies have risks and uncertainties which could lead to repeating waves of infection. We show -- as proof of concept grounded on rigorous mathematical eviden…
