A distributed Subgradient Method for Dynamic Convex Optimization Problems Under Noisy Information Exchange
收藏 引用
IEEE JOURNAL OF SELECTED TOPICS IN signal processing 2013年 第2期7卷 243-256页
作者: Cavalcante, Renato L. G. Stanczak, Slawomir Fraunhofer Heinrich Hertz Inst D-10587 Berlin Germany Tech Univ Berlin Heinrich Hertz Lehrstuhl Informat Theorie & Theor D-10623 Berlin Germany
We consider a convex optimization problem for non-hierarchical agent networks where each agent has access to a local or private time-varying function, and the network-wide objective is to find a time-invariant minimiz... 详细信息

Broadcast Gossip Algorithms for Consensus on Strongly Connected Digraphs
收藏 引用
IEEE TRANSACTIONS ON signal processing 2013年 第16期61卷 3959-3971页
作者: Wu, Shaochuan Rabbat, Michael G. McGill Univ Montreal PQ H3A 0E9 Canada McGill Univ Dept Elect & Comp Engn Montreal PQ H3A 0E9 Canada
We study a general framework for broadcast gossip algorithms which use companion variables to solve the average consensus problem. Each node maintains an initial state and a companion variable. Iterative updates are p... 详细信息

Multiscale Gossip for Efficient Decentralized Averaging in Wireless Packet Networks
收藏 引用
IEEE TRANSACTIONS ON signal processing 2013年 第9期61卷 2137-2149页
作者: Tsianos, Konstantinos I. Rabbat, Michael G. McGill Univ Dept Elect & Comp Engn Montreal PQ H3A 0E9 Canada
This paper describes and analyzes a hierarchical algorithm called Multiscale Gossip for solving the distributed average consensus problem in wireless sensor networks. The algorithm proceeds by recursively partitioning... 详细信息
