Challenging aspects in Consensus protocols for Networks
2008 3rd International Symposium on Communications, Control and Signal Processing, 2008Results on consensus protocols for networks are presented. The basic tools and the main contribution available in the literature are considered, together with some of the related challenging aspects: estimation in networks and how to deal with disturbances is considered.

Paxos in the NIC: Hardware Acceleration of Distributed Consensus Protocols
2020 16th International Conference on the Design of Reliable Communication Networks DRCN 2020, 2020Modern network infrastructures rich of logically centralized agents, such as DHCP, AAA, SDN controller agents, need to use redundancy in order to guarantee high availability and consensus protocols to have strong consistency.

Efficient decentralized consensus protocols
IEEE Transactions on Software Engineering, 1986Decentralized consensus protocols are characterized by successive rounds of message interchanges. Protocols which achieve a consensus in one round of message interchange require O(N2) messages, where N is the number of participants. A communication scheme based on finite projective planes is presented which requires only O(N√N) messages for each round.

Asynchronous consensus and broadcast protocols
Journal of the ACM, 1985A consensus protocol enables a system of n asynchronous processes, some of which are faulty, to reach agreement. There are two kinds of faulty processes: fail-stop processes that can only die and malicious processes that can also send false messages. The class of asynchronous systems with fair schedulers is defined,

The fixed-time consensus problem is considered in this paper for second-order multi-agent systems (MASs) with inherent nonlinear dynamics and disturbances under a detail-balanced network in both leaderless and leader-following cases.

Abstract We analyzenagents communicating in order to reach consensus. We show how some conditions on the topology of the communication graph (the order in which individuals communicate) are sufficient to guarantee consensus on the value of a function satisfying the “sure-thing” condition.Journal of Economic LiteratureClassification Numbers: C62, C78.

Nonlinear Consensus Protocols With Applications to Quantized Communication and Actuation
IEEE Transactions on Control of Network Systems, 2019Nonlinearities are present in all real applications. Two types of general nonlinear consensus protocols are considered in this paper, namely, the systems with nonlinear communication and actuator constraints.

Contextualizing Consensus Protocols in Blockchain: A Short Survey
International Conference on Trust, Privacy and Security in Intelligent Systems and Applications, 2019Consensus protocols are mechanisms that enable a group of entities to reach an agreement on a specific subject. In blockchain systems, consensus protocols are the cornerstone of achieving security and scalability.
