Resilience against Misbehaving Nodes in Asynchronous Networks
It tackles the problem of ensuring consensus despite misbehaving nodes in asynchronous network systems, but the results are preliminary and incremental.
This paper addresses resilient consensus in asynchronous networks where nodes update at arbitrary times, providing a first step toward resilient event-triggered and self-triggered coordination protocols.
Network systems are one of the most active research areas in the engineering community as they feature a paradigm shift from centralized to distributed control and computation. When dealing with network systems, a fundamental challenge is to ensure their functioning even when some of the network nodes do not operate as intended due to faults or attacks. The objective of this paper is to address the problem of resilient consensus in a context where the nodes have their own clocks, possibly operating in an asynchronous way, and can make updates at arbitrary time instants. The results represent a first step towards the development of resilient event-triggered and self-triggered coordination protocols.
