ABSTRACT:
This presentation studies the discrete-time system for multi-agent consensus problem based on the local group communications, i.e., the information exchange happens among the groups which are aggregations of certain agents. The exchanged information, called the representative state, is the combined states of the agents belonged to the group. This is motivated by certain real applications such as aggregating the Web pages into groups to reduce the amount of communication and computation in distributed PageRank algorithm, and distributed beamforming with feedback information, etc. First, we consider the feedback as the convex combination of all the agents' states in each group. The sufficient and necessary condition to achieve almost surely consensus is provided. Following, a detailed application in distributed beamforming is analysed.
