The problem lies at the core of the tasks of distributed synchronization, distributed coordination of mobile autonomous agents, and distributed data fusion in sensor networks. The prototypical example of a consensus problem i s that of using local communication to compute the average of a set of scala r values, measured or available at network nodes scattered throughout a moni tored region. The two most widely studied algorithms for solving the average consensus problem are distributed averaging and random gossip. The original versions of these algorithms suffer from slow convergence for the communica tion topologies commonly encountered in wireless networks (grids or random g eometric graphs). In this talk, Professor Coates will discuss two strategies for significantly accelerating the convergence rate. The first strategy inc orporates a prediction step in distributed averaging, exploiting the typical ly smooth nature of the convergence to the consensus value. The second strat egy modifies random gossip, allowing each node to select its gossip-partner to myopically maximize the migration towards consensus. 此报告为前沿技术讲座，欢迎全校师生踊跃参加。校学术委员会信息与通信工程学院多媒体通信中心 2009年4月10日附：Coates教授简介 Mark Coates received the B.E. degree (first class honours) in computer syste ms engineering from the University of Adelaide, Australia, in 1995, and a Ph .D. degree in information engineering from the University of Cambridge, U.K. , in 1999. He was awarded the Texas Instruments Postdoctoral Fellowship in 1 999 and was a research associate and lecturer at Rice University, Texas, fro m 1999-2001. He joined the Department of Electrical and Computer Engineering of McGill University (Montreal, Canada) in 2002, where he is currently an A ssociate Professor. His research interests include communication and sensor/ actuator networks, statistical signal processing, and Bayesian and Monte Car lo inference.
