Consensus with Ternary Messages
We provide a protocol for real-valued average consensus by networks of agents
which exchange only a single message from the ternary alphabet {-1,0,1} between
neighbors at each step. Our protocol works on time-varying undirected graphs
subject to a connectivity condition, has a worst-case convergence time which is
polynomial in the number of agents and the initial values, and requires no
global knowledge about the graph topologies on the part of each node to
implement except for knowing an upper bound on the degrees of its neighbors
