Analysis of Age of Information for A Discrete-Time hybrid Dual-Queue System

Zhengchuan Chen, Yi Qu, Nikolaos Pappas +3

Using multiple sensors to update the status process of interest is promising in improving the information freshness. The unordered arrival of status updates at the monitor end pose…

Age of Information Versions: a Semantic View of Markov Source Monitoring

Mehrdad Salimnejad, Marios Kountouris, Anthony Ephremides +1

We consider the problem of real-time remote monitoring of a two-state Markov process, where a sensor observes the state of the source and makes a decision on whether to transmit th…

Optimizing Information Freshness in IoT Systems with Update Rate Constraints: A Token-Based Approach

Erfan Delfani, Nikolaos Pappas

In Internet of Things (IoT) status update systems, where information is sampled and subsequently transmitted from a source to a destination node, the imperative necessity lies in m…

Semantic Text Transmission via Prediction with Small Language Models: Cost-Similarity Trade-off

Bhavani A Madhabhavi, Gangadhar Karevvanavar, Rajshekhar V Bhat +1

We consider the communication of natural language text from a source to a destination over noiseless and character-erasure channels. We exploit language's inherent correlations and…

Boosting Dynamic TDD in Small Cell Networks by the Multiplicative Weight Update Method

Jiaqi Zhu, Nikolaos Pappas, Howard H. Yang

We leverage the Multiplicative Weight Update (MWU) method to develop a decentralized algorithm that significantly improves the performance of dynamic time division duplexing (D-TDD…

Version Innovation Age and Age of Incorrect Version for Monitoring Markovian Sources

Mehrdad Salimnejad, Marios Kountouris, Anthony Ephremides +1

In this paper, we propose two new performance metrics, coined the Version Innovation Age (VIA) and the Age of Incorrect Version (AoIV) for real-time monitoring of a two-state Marko…
