Synchronization of pulse-coupled oscillators (PCOs) has gained significantattention recently due to increased applications in sensor networks andwireless communications. Given the distributed and unattended nature ofwireless sensor networks, it is imperative to enhance the resilience ofpulse-based synchronization against malicious attacks. However, most existingresults on resilient PCO synchronization are obtained for all-to-all networks.We propose a new pulse-based synchronization mechanism to improve theresilience of PCO synchronization that is applicable under general connectedtopologies. Under the proposed synchronization mechanism, we rigorouslycharacterize the condition for stealthy Byzantine attacks and prove thatperfect synchronization of legitimate oscillators can be guaranteed in thepresence of multiple stealthy Byzantine attackers, irrespective of whether theattackers collude with each other or not. The new mechanism can guaranteeresilient synchronization even when the initial phases of legitimateoscillators are widely distributed in a half circle, which is in distinctdifference from most existing attack-resilient synchronization algorithms(including the seminal paper from Lamport and Melliar-Smith [1]) that require apriori (almost) synchronization among legitimate oscillators. Numericalsimulation results are given to confirm the theoretical results.
