Goal-Oriented Communications for Remote Inference under Two-Way Delay with Memory Ari, Cagri; Shisher, Md Kamran Chowdhury; Uysal, Elif; Sun, Yin (2024-01-01) We study the design of a goal-oriented sampling and scheduling strategy through a channel with highly variable two-way random delay, which can exhibit memory (e.g., Delay and Disruption Tolerant Networks). The objective of...
A3L-FEC-FSFB: Age-Aware Application Layer Forward Error Correction with Fixed Sampling Rate and Fixed Block-length Baghaee, Sajjad; Uysal, Elif (2024-01-01) The concept of Age of Information (AoI) has emerged as a measure of data freshness in status-update-oriented applications. Enhancing AoI often involves unconventional networking strategies that adjust update transmission r...
Implementation of an AoI-Aware Wi-Fi Network Bilgi Yaşına Duyarlı Wi-Fi Ağı Gerçeklemesi Balcı, Alperen; Saatçi, Batu; Atak, Emir; Uysal, Elif (2024-01-01) In this paper, a method to prioritize the transmissions by considering the Age Of Information (AoI) metric is presented in communication systems that are compatible with IEEE 802.11 standard. The proposed method includes L...
DCCTA: Age of Information in Slotted ALOHA Under Duty Cycle Constraints Yavascan, Orhan T.; Ahmetoglu, Mutlu; Uysal, Elif; Gurbuz, Umut; Gencay, Omer; Balci, Alperen (2024-01-01) Slotted ALOHA has been receiving renewed interest due to its suitability as a channel access scheme in low-overhead IoT and LP-WAN scenarios. Threshold ALOHA (TA) is a modification of slotted ALOHA where users only become ...
Ensuring a Semantically Effective IoT Network Through Blockchain with Delayed Feedback Gencay, Omer; Balci, Alperen; Ceran Arslan, Elif Tuğçe; Uysal, Elif (2024-01-01) In this paper, we propose a delay-tolerant blockchain-enabled low-power wide area network. We consider the scenario of a set of information sources (e.g. sensors, IoT nodes) equipped with transceivers, accessing a common g...
Resource Allocation in the Finite Blocklength Regime Under PAoI and Delay Violation Constraints Kartal, Özkan Tuğberk; KAYA, ONUR; Uysal, Elif (2023-12-22)
Pull or Wait: How to Optimize Query Age of Information Ildiz, M. Emrullah; Yavascan, Orhan T.; Uysal, Elif; Kartal, O. Tugberk (2023-01-01) We study a pull-based status update communication model where a source node submits update packets to a channel with random transmission delay, at times requested by a remote destination node. The objective is to minimize ...
MiSTA: An Age-Optimized Slotted ALOHA Protocol Ahmetoglu, Mutlu; Yavascan, Orhan Tahir; Uysal, Elif (2022-09-01) We introduce minislotted threshold ALOHA (MiSTA), a slotted ALOHA modification designed to minimize the network-wide time average Age of Information (AoI). In MiSTA, sources whose ages are below a certain threshold stay si...
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; Soret, Beatriz; Soleymani, Touraj; Johansson, Karl Henrik (2022-7-01) We present our vision for a departure from the established way of architecting and assessing communication networks, by incorporating the semantics of information, defined not necessarily as the meaning of the messages, bu...
Implementation and Evaluation of Age-Aware Downlink Scheduling Policies in Push-Based and Pull-Based Communication Oğuz, Tahir Kerem; Ceran Arslan, Elif Tuğçe; Uysal, Elif; Girici, Tolga (2022-5-01) As communication systems evolve to better cater to the needs of machine-type applications such as remote monitoring and networked control, advanced perspectives are required for the design of link layer protocols. The age ...
