Timely Persuasion with Opposing Senders: When Does Competition Help the Receiver?
Ahmet Bugra Gundogan, Melih Bastopcu
Status updates let a receiver track a changing process, but a sender that controls when they are sent can steer the receiver's estimate without misreporting. We study competition b…
Strategic Information Transmission over Gossip Networks
Emirhan Tekez, Melih Bastopcu, Sinan Gezici
We consider a fully connected gossip network of nodes that track a binary continuous-time Markov source through a strategic sender transmitting updates under a communication bu…
Keep, Customize, or Exit: Default Design and Token Pricing in LLM Reasoning Services
Ahmet Bugra Gundogan, Yigit Turkmen, Melih Bastopcu
We study a large language model (LLM) service in which a provider chooses a per-token price and a default reasoning-token allocation, while a user may accept the default, customize…
Strategic Persuasion Through Information Timeliness
Ahmet Bugra Gundogan, Melih Bastopcu
We study a dynamic strategic communication problem in which a sender controls the timing of truthful updates from binary continuous-time Markov sources. The receiver chooses betwee…
Characterizing Information Accuracy in Timeliness-Based Gossip Networks
Emirhan Tekez, Melih Bastopcu, Sinan Gezici
We investigate information accuracy in timeliness-based gossip networks where the source evolves according to a continuous-time Markov chain (CTMC) with states and disseminates…
Don't Always Pick the Highest-Performing Model: An Information Theoretic View of LLM Ensemble Selection
Yigit Turkmen, Baturalp Buyukates, Melih Bastopcu
Large language models (LLMs) are often ensembled together to improve overall reliability and robustness, but in practice models are strongly correlated. This raises a fundamental q…
Queueing-Aware Optimization of Reasoning Tokens for Accuracy-Latency Trade-offs in LLM Servers
Emre Ozbas, Melih Bastopcu
We consider a single large language model (LLM) server that serves a heterogeneous stream of queries belonging to distinct task types. Queries arrive according to a Poisson pro…
Timely Information for Strategic Persuasion
Ahmet Bugra Gundogan, Melih Bastopcu
This work investigates a dynamic variant of Bayesian persuasion, in which a strategic sender seeks to influence a receiver's belief over time through controlling the timing of the…
A Soft Inducement Framework for Incentive-Aided Steering of No-Regret Players
Asrin Efe Yorulmaz, Raj Kiriti Velicheti, Melih Bastopcu +1
In this work, we investigate a steering problem in a mediator-augmented two-player normal-form game, where the mediator aims to guide players toward a specific action profile throu…
Balancing Information Accuracy and Response Timeliness in Networked LLMs
Yigit Turkmen, Baturalp Buyukates, Melih Bastopcu
Recent advancements in Large Language Models (LLMs) have transformed many fields including scientific discovery, content generation, biomedical text mining, and educational technol…
How to Maximize Efficiency in Systems with Exhausted Workers
Elif Beray Sariisik, Melih Bastopcu, Nail Akar +1
We consider the problem of assigning tasks efficiently to a set of workers that can exhaust themselves as a result of processing tasks. If a worker is exhausted, it will take a lon…
Distributed Offloading in Multi-Access Edge Computing Systems: A Mean-Field Perspective
Shubham Aggarwal, Muhammad Aneeq uz Zaman, Melih Bastopcu +2
Multi-access edge computing (MEC) technology is a promising solution to assist power-constrained IoT devices by providing additional computing resources for time-sensitive tasks. I…
Fully Decentralized Computation Offloading in Priority-Driven Edge Computing Systems
Shubham Aggarwal, Melih Bastopcu, Muhammad Aneeq uz Zaman +3
We develop a novel framework for fully decentralized offloading policy design in multi-access edge computing (MEC) systems. The system comprises power-constrained user equipmen…
Remote Estimation Games with Random Walk Processes: Stackelberg Equilibrium
Atahan Dokme, Raj Kiriti Velicheti, Melih Bastopcu +1
Remote estimation is a crucial element of real time monitoring of a stochastic process. While most of the existing works have concentrated on obtaining optimal sampling strategies,…
Age of Coded Updates In Gossip Networks Under Memory and Memoryless Schemes
Erkan Bayram, Melih Bastopcu, Mohamed-Ali Belabbas +1
We consider an information update system on a gossip network, where a source node encodes information into total keys such that any subset of at least keys can fully reco…
Modeling Interfering Sources in Shared Queues for Timely Computations in Edge Computing Systems
Nail Akar, Melih Bastopcu, Sennur Ulukus +1
Most existing stochastic models on age of information (AoI) focus on a single shared server serving status update packets from sources where each packet update stream is Pois…
Semantic Communication in Multi-team Dynamic Games: A Mean Field Perspective
Shubham Aggarwal, Muhammad Aneeq uz Zaman, Melih Bastopcu +1
Coordinating communication and control is a key component in the stability and performance of networked multi-agent systems. While single user networked control systems have gained…
Optimizing Profitability in Timely Gossip Networks
Priyanka Kaswan, Melih Bastopcu, Sennur Ulukus +2
We consider a communication system where a group of users, interconnected in a bidirectional gossip network, wishes to follow a time-varying source, e.g., updates on an event, in r…
How to Make Money From Fresh Data: Subscription Strategies in Age-Based Systems
Priyanka Kaswan, Melih Bastopcu, Sennur Ulukus +2
We consider a communication system consisting of a server that tracks and publishes updates about a time-varying data source or event, and a gossip network of users interested in c…
