Distributed Data Placement and Content Delivery in Web Caches with Non-Metric Access Costs

SR Etesami - Proceedings of the ACM on Web Conference 2024, 2024 - dl.acm.org
Motivated by applications in web caches and content delivery in peer-to-peer networks, we

How bad is selfish caching?

Q Ma, E Yeh, J Huang - Proceedings of the Twentieth ACM International …, 2019 - dl.acm.org
Caching networks can reduce the routing costs of accessing contents by caching contents
closer to users. However, cache nodes may belong to different entities and behave selfishly …

Pure Nash equilibrium in a capacitated selfish resource allocation game

SR Etesami, T Başar - IEEE Transactions on Control of …, 2016 - ieeexplore.ieee.org
A resource allocation game with identical preferences is considered where each player, as a
node of an undirected unweighted network, tries to minimize his or her cost by caching an …

Price of anarchy and an approximation algorithm for the binary-preference capacitated selfish replication game

SR Etesami, T Başar - Automatica, 2017 - Elsevier
We consider the capacitated selfish replication (CSR) game with binary preferences, over
general undirected networks. We study the price of anarchy of such games, and show that it …
