Age of Information in Practice
Uysal, Elif; Kaya, Onur; Baghaee, Sajjad; Beytur, Hasan Burhan (Cambridge University Press, 2023)While age of Information (AoI) has gained importance as a metric characterizing the freshness of information in information-update systems and time-critical applications, most previous studies on AoI have been theoretical. ... -
Improving age of information in random access channels
Atabay, Doğa Can; Uysal, Elif; Kaya, Onur (Institute of Electrical and Electronics Engineers Inc., 2020-07)We study Age of Information (AoI) in a random access channel where a number of devices try to send status updates over a common medium. Assuming a time-slotted scenario where multiple transmissions result in collision, we ... -
Resource allocation in the finite blocklength regime under PAoI and delay violation constraints
Kartal, Özkan Tuğberk; Kaya, Onur; Uysal, Elif (IEEE, 2023-08-27)URLLC (Ultra-reliable low-latency communication) is one of the more challenging modes for 5G for resource allocation (RA). Most of the previous studies for RA for wireless access in URLLC assumed known packet arrival ... -
Semantic communications in networked systems: a data significance perspective
Uysal, Elif; Kaya, Onur; Ephremides, Anthony; Gross, James; Codreanu, Marian; Popovski, Petar; Assaad, Mohamad; Liva, Gianluigi; Munari, Andrea; Soleymani, Touraj; Soret, Beatriz; Johansson, Karl Henrik (IEEE, 2022-07-01)We present our vision for a departure from the established way of architecting and assessing communication networks, by incorporating the semantics of information for communications and control in networked systems. We ... -
When to pull data for minimum age penalty
Yavaşcan, Orhan Tahir; Ceran, Elif Tuğçe; Cakir, Zeynep; Uysal, Elif; Kaya, Onur (IEEE, 2021-10-18)A communication receiver that wants to pull data from a remote sensor by exploiting wireless energy transfer is considered. The receiver has a long-term average energy budget for this operation, and its goal is to keep the ...
