Grainger Lecture: Distributed Stopping and Privacy-Preservation in Average Consensus

Speaker Christoforos Hadjicostis, Professor of Electrical and Computer Engineering, University of Cyprus
Date: 7/2/2014
Time: 4:00 pm
Location: CSL Auditorium (B02)
Sponsor: Grainger Lecture Series
Event Type: Academic
  In this talk we analyze enhancements for iterative strategies that enable the components of a distributed system, each with some initial value, to asymptotically reach consensus to the average of these initial values. The algorithms we propose can be used in practical settings (e.g., coordination of distributed energy resources) to cap the number of iterations and/or transmissions, and to ensure privacy while reaching average consensus. We first discuss how iterative strategies for asymptotic average consensus, in possibly directed communication topologies (digraphs), can be adapted so that the nodes can determine, in a distributed manner, when approximate average consensus has been reached (i.e., when their values are close to the desirable average). We then discuss strategies that enable the nodes to asymptotically reach consensus to the average of their initial values, without having to reveal the specific value they contribute to the average calculation.
