Asynchronous Consensus Protocols: Preliminary Results, Simulations and Open Questions

Summary: Asynchronous Consensus Protocols: Preliminary Results,
Simulations and Open Questions
Lei Fang, Panos J. Antsaklis, and Anastasis Tzimas
Abstract-- Consensus is well accepted as being a fundamental
paradigm for coordination of groups of autonomous agents.
Recently, we casted previous work on multi-agent consensus
protocols into an asynchronous framework, where each agent
updates on its own pace, and uses the most recently received in-
formation from other agents. Asynchronous consensus protocols
encompass those synchronous ones with various communication
patterns. In this paper, we study via simulation a number of
open new problems introduced by the asynchronous operation
of multi-agent systems. More interestingly, the existing consen-
sus results are classified by their communication assumptions
and future research directions are proposed. To facilitate our
study, we develop a multi-vehicle simulator in Java, built on
top of JProwler; JProwler is a discrete event simulator for
prototyping, verifying and analyzing communication protocols
of ad-hoc wireless networks. Implementation issues with their
implications are also discussed.
