Abstract:

This paper studies the problem of distributed consensus in the presence of spurious sensor information. We propose a new method, De-RANSAC, which allows a multi-agent system to detect outliers---erroneous measurements or incorrect hypotheses---when the sensed information is gathered in a distributed way. The method is an extension of the RANSAC (RANdom SAmple Consensus) algorithm, which leads to a consensus result on the goodness of a set of measurements with certain probability. In order to execute the full process in a decentralized way, we propose a distributed voting policy valid for fixed and switching topologies. Simulations of real applications are provided showing the reliability of the proposed method.
