To effectively extract the information from sensor arrays, an online sensor scheduling strategy based on similarity of measurement data is introduced. The observability of systems equipped with dynamic spatial-temporal data selection mechanisms (consisting of event-based and sensor scheduling protocols) is analyzed, where a criterion for [Formula: see text]-observability is derived. Furthermore, an event-based state estimator aimed at obtaining ellipsoidal regions containing system states is designed. The convergence property of the proposed state estimation algorithm is proved through analyzing the asymptotic boundness of sizes of the estimated state ellipsoids. A comparative analysis of estimation performances with and without sensor scheduling is conducted. The computational complexity of the designed state estimation algorithm is also discussed. Finally, the effectiveness of the proposed event-based estimator is demonstrated by numerical simulations.<\/jats:p>","DOI":"10.1137\/24m1670792","type":"journal-article","created":{"date-parts":[[2026,5,20]],"date-time":"2026-05-20T07:15:51Z","timestamp":1779261351000},"page":"1433-1455","source":"Crossref","is-referenced-by-count":0,"title":["Data Scheduling and State Estimation for Large-Scale Event-Based Sensor Arrays"],"prefix":"10.1137","volume":"64","author":[{"given":"Xinhui","family":"Liu","sequence":"first","affiliation":[{"name":"MIIT Key Laboratory of Servo Motion System Drive and Control, School of Automation, Beijing Institute of Technology, Beijing, 100081 China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dawei","family":"Shi","sequence":"additional","affiliation":[{"name":"Corresponding author.
