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 + ⌈log1+δ Ω⌉ iterations where δ > 0 depends on the network topology and O is a polynomial of the quantization resolution,...
We consider the convergence time for solving the binary interval consensus problem using a distributed algorithm proposed by Benezit at al (2009) for computing the quantized average value. In the binary consensus problem, each node initially holds one of two states and the goal for each node is to correctly decide which one of the two states was initially held by a majority of nodes. We derive an...
