Abstract

This paper considers a probabilistic local polling process, examines its properties and proposes its use in the context of distributed network protocols for achieving consensus. The resulting consensus algorithm is very simple and light-weight, yet it enjoys some desirable properties, such as proportionate agreement (namely, reaching a consensus value of one with probability proportional to the number of ones in the inputs), resilience against dynamic link failures and recoveries, and (weak) self-stabilization.
