In this paper, we present a leader election protocol in the population protocol model that
stabilizes within O (log n) parallel time in expectation with O (log n) states per agent, where n …

Time-optimal self-stabilizing leader election in population protocols

J Burman, HL Chen, HP Chen, D Doty… - Proceedings of the …, 2021 - dl.acm.org
We consider the standard population protocol model, where (a priori) indistinguishable and
anonymous agents interact in pairs according to uniformly random scheduling. The self …

Loosely-self-stabilizing Byzantine-tolerant binary consensus for signature-free message-passing systems

C Georgiou, I Marcoullis, M Raynal… - … Conference on Networked …, 2021 - Springer
Abstract At PODC 2014, A. Mostéfaoui, H. Moumen, and M. Raynal presented a new and
simple randomized signature-free binary consensus algorithm (denoted here as MMR) that …

Leader election requires logarithmic time in population protocols

Y Sudo, T Masuzawa - Parallel Processing Letters, 2020 - World Scientific
This paper shows that every leader election protocol requires logarithmic stabilization time
both in expectation and with high probability in the population protocol model. This lower …

Time-optimal loosely-stabilizing leader election in population protocols

Y Sudo, R Eguchi, T Izumi, T Masuzawa - arXiv preprint arXiv:2005.09944, 2020 - arxiv.org
We consider the leader election problem in population protocol models. In pragmatic
settings of population protocols, self-stabilization is a highly desired feature owing to its fault …

Self-stabilizing population protocols with global knowledge

Y Sudo, M Shibata, J Nakamura, Y Kim… - … on Parallel and …, 2021 - ieeexplore.ieee.org
In the population protocol model, many problems cannot be solved in a self-stabilizing
manner. However, global knowledge, such as the number of nodes in a network, sometimes …

Self-stabilizing byzantine-tolerant recycling

C Georgiou, M Raynal, EM Schiller - … on Stabilizing, Safety, and Security of …, 2023 - Springer
Numerous distributed applications, such as cloud computing and distributed ledgers,
necessitate the system to invoke asynchronous consensus objects for an unbounded …

Loosely stabilizing leader election on arbitrary graphs in population protocols without identifiers or random numbers

Y Sudo, F Ooshita, H Kakugawa… - … on Information and …, 2020 - search.ieice.org
We consider the leader election problem in the population protocol model, which Angluin et
