Average bandwidth-cost vs. storage trade-off for bs-assisted distributed storage networks
Pourmandi, Massoud; Arslan, Şuayb Şefik; Pusane, Ali Emre; Haytaoğlu, Elif; Tengiz, Ayse Ceyda (IEEE, 2021)In this study, we consider a hierarchically structured base station (BS)-assisted cellular system equipped with a backend distributed data storage in which nodes randomly arrive and depart the cell. We numerically motivate ... -
Base Station-Assisted Cooperative Network Coding for Cellular Systems with Link Constraints
Arslan, Şuayb Şefik; Pourmandi, Massoud; Haytaoğlu, Elif (IEEE, 2022)We consider a novel distributed data storage/caching scenario in a cellular network, where multiple nodes may fail/depart simultaneously To meet reliability, we allow cooperative regeneration of lost nodes with the help ... -
Cooperative network coding for distributed storage using base stations with link constraints
Arslan, Şuayb Şefik; Pourmandi, Massoud; Haytaoğlu, Elif (arXiv, 2021)In this work, we consider a novel distributed data storage/caching scenario in a cellular setting where multiple nodes may fail/depart at the same time. In order to maintain the target reliability, we allow cooperative ... -
Cost of guessing: applications to data repair
Arslan, Şuayb Şefik; Haytaoğlu, Elif (Institute of Electrical and Electronics Engineers Inc., 2020)In this paper, we introduce the notion of cost of guessing and provide an optimal strategy for guessing a random variable taking values on a finite set whereby each choice may be associated with a positive finite cost ... -
Data repair in BS-assisted distributed data caching
Kaya, Erdi; Haytaoğlu, Elif; Arslan, Şuayb Şefik (IEEE, 2020)In this paper, centralized and independent repair approaches based on device-to-device communication for the repair of the lost nodes have been investigated in a cellular network where distributed caching is applied whose ... -
Improved bounds on the moments of guessing cost
Arslan, Şuayb Şefik; Haytaoğlu, Elif (IEEE, 2022)Guessing a random variable with finite or countably infinite support in which each selection leads to a positive cost value has recently been studied within the context of "guessing cost". In those studies, similar to ...
