University of Maryland, College Park, MD, USAWith emerging technologies such as autonomous driving, augmented reality, high-frequency automated trading, and online gaming, time sensitive information has become ever more critical. In order to measure the timeliness of the information in communication networks, age of information has been proposed which is different than more traditional performance metrics such as delay and throughput. In order to attain good age performance, status updates need to be delivered regularly with low delay. In this seminar, I will talk about fundamental solutions for timely update delivery problems in communications networks with various system settings. Specifically, I will discuss the trade-off between age and the quality of the updates which arises in sensor networking and distributed computation applications, characterization, and then maximization of the freshness of information in cache updating systems, timely updating of the citation records of a group of researchers, who have different mean citation rates, with a resource-constrained updater, i.e., Google Scholar, timely tracking of infectious diseases, e.g., covid-19, status of individuals in a population under limited total test rate constraint for the health care provider.
Bio: Melih Bastopcu received his B.S. degree from the Department of Electrical and Electronics Engineering from Bilkent University, Turkey in June 2016. At present, he is a Ph.D. candidate in the Department of Electrical and Computer Engineering, at University of Maryland. His research focus is on age of information, resource allocation, low latency systems and communication network design.
