Consensus in context : leveraging the network to accelerate distributed consensus
Gossip algorithms are a class of decentralized solutions to theproblem of achieving consensus in a network of agents. Theyhave attracted recent research interest because they are simpleand robust -- attractive qualities for wireless ad-hoc and sensornetworks. Unfortunately, the standard gossip protocol convergesvery slowly for many popular network models. I will discuss threeways to leverage properties of the network to achieve fasterconvergence : routing, broadcast, and mobility.
