Abstract
Large-scale sensor networks give rise to estimation problems that have a rich graphical structure. We studied one of these problems in terms of how such an estimate can be efficiently computed in a distributed manner as well as how the quality of an optimal estimate scales with the size of the network. Two distributed algorithms are presented to compute the optimal estimates that are scalable and robust to communication failures. In designing these algorithms, we found the literature on parallel computation to be a rich source of inspiration.

Coherence in Large-Scale Networks: Dimension-Dependent Limitations of Local Feedback

TL;DR: It is shown that it is impossible to have large coherent 1-D vehicular platoons with only local feedback, and that in low spatial dimensions, local feedback is unable to regulate large-scale disturbances, but it can in higher spatial dimensions.

Coordination and Consensus of Networked Agents with Noisy Measurements: Stochastic Algorithms and Asymptotic Behavior

TL;DR: In this paper, the authors consider the coordination and consensus of networked agents where each agent has noisy measurements of its neighbors' states and propose stochastic approximation-type algorithms with a decreasing step size, and introduce the notions of mean square and strong consensus.

Algorithms for Leader Selection in Stochastically Forced Consensus Networks

TL;DR: This work shows that the Boolean constraints (which indicate whether a node is a leader) are the only source of nonconvexity, and develops a customized algorithm well-suited for large networks.

Random walks and electric networks

TL;DR: The goal will be to interpret Polya’s beautiful theorem that a random walker on an infinite street network in d-dimensional space is bound to return to the starting point when d = 2, but has a positive probability of escaping to infinity without returning to the Starting Point when d ≥ 3, and to prove the theorem using techniques from classical electrical theory.
