Abstract: we consider the average-consensus problem in a multi-node network of finite size. Communication between nodes is modeled by a sequence of directed signals with arbitrary communication delays. Four distributed algorithms that achieve average-consensus are proposed.
Distributed average consensus with deterministic quantization: an admm approach. Abstract: this paper develops efficient algorithms for distributed average consensus with quantized communication using the alternating direction method of multipliers (admm). When rounding quantization is employed, a distributed admm algorithm is shown to converge to a consensus within 3 + ⌈log 1+δ ω⌉ iterations where δ 0 depends on the network topology and ω is a polynomial of the quantization.
We describe a protocol for the average consensus problem on any fixed undirected examining distributed and centralized stochastic gradient descent.
First, a review of graph notions relevant to this note is provided; and then, the average consensus problem on deterministic time-varying networks is formulated.
Distributed averaging algorithms fail to achieve consensus when deterministic uniform quantization is adopted.
Average-consensus formation implies that a group of distinct nodes come to agree on the average of their initial values, see [3], [7], [10], [19], [21], [29], [6] for related work. Past results indicate that obtaining average-consensus on a set of of n initial vectors each with dimension d requires at least one of the following assumptions:.

Abstract—this paper concerns the average consensus problem.

One commonly adopted consensus scheme is the deterministic average consensus algorithm, where each agent communicates with a fixed set of neighbors and follows a time-invariant update algorithm to reach the average of their initial values.
Aug 10, 2009 we give a fast deterministic consensus algorithm that has processes send only o (n log4 n) bits.
Averaging can be treated as a special case of consensus – average consensus.
A novel distributed-averaging (da) algorithm is presented and shown to achieve average-consensus if at any time t there exists a finite time interval [t, tt] over which each node can communicate.
Abstract—average consensus is a widely used algorithm for distributed computing and the consensus algorithm is deterministic and agent n can perfectly infer.

In this paper, we analyze distributed average consensus algorithms, both deterministic and gossip based, with respect to a new metric related to the energy cost.
Abstract in the average consensus problem the states of a set of agents, linked according to a directed graph, have to be driven to their average.
We study the distributed average consensus problem in multiagent systems with directed communication links that are subject to quantized information flow. The goal of distributed average consensus is for the nodes, each associated with some initial value, to obtain the average (or some value close to the average) of these initial values.

This paper considers the average-consensus problem in a network with arbitrary (but finite) communication delays.
