Population Protocols with Faulty Interactions: the Impact of a Leader [article]

Giuseppe Antonio Di Luna, Paola Flocchini, Taisuke Izumi, Tomoko Izumi, Nicola Santoro, Giovanni Viglietta
2016 arXiv   pre-print
We focus on the impact of a leader, and we give a complete characterization of the models in which the presence of a unique leader in the system allows the construction of simulators: when simulations  ...  We consider the problem of simulating traditional population protocols under weaker models of communication, which include one-way interactions (as opposed to two-way interactions) and omission faults  ...  We study the negative impact that omissions have on computability, and we show that the simulation of two-way protocols is impossible even with the aid of a leader (Theorem 1), assuming that the amount  ...

Stabilizing Tiny Interaction Protocols [article]

Davide Canepa, Maria Gradinariu Potop-Butucaru
2010 arXiv   pre-print
Interestingly, our work proposes for the first time a model that unifies the recent studies in mobile robots(agents) that evolve in a discrete space and the already established population protocols paradigm  ...  In this paper we present the self-stabilizing implementation of a class of token based algorithms. In the current work we only consider interactions between weak nodes.  ...  Our contribution We propose a novel model of interactions that extends the population protocols with the power of agents and oracles schemes.  ...

2015 Proceedings of the 24th International Symposium on High-Performance Parallel and Distributed Computing - HPDC '15  
In this paper, we propose a new set of protocols based on Remote Direct Memory Access (RDMA) primitives.  ...  To asses these mechanisms, we use a strongly consistent key-value store; the evaluation shows that our simple protocols improve RSM performance by more than an order of magnitude.  ...  We thank our shepherd Jay Lofstead, the anonymous reviewers; Miguel Castro for his insightful feedback; Timo Schneider for helpful discussions; and the Systems Group at ETH Zurich for providing us the  ...

Byzantine-Resilient Population Protocols [article]

Costas Busch, Dariusz R. Kowalski
2021 arXiv   pre-print
The only other known previous work on Byzantine-resilient population protocols tolerates up to f = o(√(n)) faulty nodes and was analyzed against a Static adversary; hence, our protocols significantly improve  ...  Most of the population protocols in the literature assume that the participating n nodes are honest. Such an assumption may not be, however, accurate for large-scale systems of small devices.  ...  A node u with value B will cancel its value if it interacts with one of the nodes with value A, which are at least n/8 throughout the phase, or if it interacts with a faulty node.  ...
