We present Bullshark, the first directed acyclic graph (DAG) based asynchronous Byzantine
Atomic Broadcast protocol that is optimized for the common synchronous case. Like …

This book presents the most important fault-tolerant distributed programming abstractions
and their associated distributed algorithms, in particular in terms of reliable communication …

Due to the increasing functionality and complexity of Cloud computing systems, the resource
failures, including unpredictable crash and performance degradation about resource …

Designing protocols for solving the consensus problem faces new challenges in mobile
computing environments. Among others, how we can achieve message efficiency for saving …

Atomic multicast is a communication primitive that delivers messages to multiple groups of
processes according to some total order, with each group receiving the projection of the total …

In distributed systems, failure detectors are used to monitor the processes and to reduce the
risk of failures by detecting them before system crashes. Accuracy and completeness are the …

This work introduces the Distributed Network Reachability (DNR) algorithm, a distributed
system-level diagnosis algorithm that allows every node of a partitionable arbitrary topology …

Unreliable failure detectors are mechanisms providing information about process failures,
that allow to solve several problems in asynchronous systems, eg, Consensus. A particular …

This paper proposes a modular approach to the design of hierarchical consensus protocols
for the mobile ad hoc network with a static and known set of hosts. A two-layer hierarchy is …

This proposed failure detector algorithm of the Perfect P class is implemented for the
hierarchical synchronous distributed systems. There are several failure detection …
