Failure Detectors in Homonymous Distributed Systems (with an Application to Consensus)
Sergio Arévalo, Antonio Fernández Anta, Damien Imbs +2
This paper addresses the consensus problem in homonymous distributed systems where processes are prone to crash failures and have no initial knowledge of the system membership ("ho…
Greening File Distribution: Centralized or Distributed?
Kshitiz Verma, Gianluca Rizzo, Antonio Fernández Anta +2
Despite file-distribution applications are responsible for a major portion of the current Internet traffic, so far little effort has been dedicated to study file distribution from…
A Game Theoretic Approach to Distributed Opportunistic Scheduling
Albert Banchs, Andres Garcia-Saavedra, Pablo Serrano +1
Distributed Opportunistic Scheduling (DOS) is inherently harder than conventional opportunistic scheduling due to the absence of a central entity that has knowledge of all the chan…
Unbounded Contention Resolution in Multiple-Access Channels
Antonio Fernández Anta, Miguel A. Mosteiro, Jorge Ramón Muñoz
A frequent problem in settings where a unique resource must be shared among users is how to resolve the contention that arises when all of them must use it, but the resource allows…
Probabilistic Bounds on the Length of a Longest Edge in Delaunay Graphs of Random Points in d-Dimensions
Esther M. Arkin, Antonio Fernandez Anta, Joseph S. B. Mitchell +1
Motivated by low energy consumption in geographic routing in wireless networks, there has been recent interest in determining bounds on the length of edges in the Delaunay graph of…
Opportunistic Information Dissemination in Mobile Ad-hoc Networks: adaptiveness vs. obliviousness and randomization vs. determinism
Martin Farach-Colton, Antonio Fernandez Anta, Alessia Milani +2
In this paper the problem of information dissemination in Mobile Ad-hoc Networks (MANET) is studied. The problem is to disseminate a piece of information, initially held by a disti…
