Privacy-Preserving Average Consensus Algorithm Under Round-Robin Scheduling Protocol

Dear Editor, Over the past decades, cooperative control and distributed optimization have gained significant research attention due to their broad applications such as signal processing, robotics, and social networks [1], [2]. As a fundamental component of distributed control and optimization, the issue of average consensus has become a recurring topic of interest [3], [4]. To achieve average consensus, it is essential to establish a distributed algorithm with local information under which each node is able to adjust its own behavior by exchanging information with its neighbors instead of relying on a central node.
