Packet Efficient Implementation of the Omega Failure Detector [article]

Quentin Bramas, Dianne Foreback, Mikhail Nesterenko, Sébastien Tixeuil
2016 arXiv   pre-print
We assume that a message may be delivered by packets through multiple hops and investigate the feasibility and efficiency of an implementation of the Omega Failure Detector under such an assumption.To  ...  On the constructive side, we present and prove correct a deterministic packet efficient implementation of Omega that matches the necessary conditions we established.  ...  Algorithm MPO is a message and packet efficient implementation of Omega in the fair-lossy channel model. Proof: First, we prove that MPO implements Omega.  ...
