Fundamental limits of combinatorial multi-access caching

F Brunero, P Elia - IEEE Transactions on Information Theory, 2022 - ieeexplore.ieee.org
This work identifies the fundamental limits of multi-access coded caching (MACC) where
each user is connected to multiple caches in a manner that follows a generalized …

Fresh caching of dynamic content over the wireless edge

B Abolhassani, J Tadrous, A Eryilmaz… - IEEE/ACM Transactions …, 2022 - ieeexplore.ieee.org
We introduce a framework and provably-efficient schemes for 'fresh'caching at the (front-
end) local cache of content that is subject to 'dynamic'updates at the (back-end) database …

On the optimal load-memory tradeoff of cache-aided scalar linear function retrieval

K Wan, H Sun, M Ji, D Tuninetti… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
Coded caching has the potential to greatly reduce network traffic by leveraging the cheap
and abundant storage available in end-user devices so as to create multicast opportunities …

Multiaccess coded caching with private demands

K Wan, M Cheng, D Liang… - 2022 IEEE International …, 2022 - ieeexplore.ieee.org
Hachem et al. formulated a multiaccess coded caching model which consists of a central
server connected to K users via an error-free shared link, and K cache-nodes. Each cache …

Demand privacy in hotplug caching systems

Y Ma, D Tuninetti - 2023 IEEE International Symposium on …, 2023 - ieeexplore.ieee.org
Coded caching, introduced by Maddah-Ali and Niesen (MAN), is a model where a server
broadcasts multicast packets to users with a local cache that is leveraged so as to reduce …

On the fundamental limits of cache-aided multiuser private information retrieval

X Zhang, K Wan, H Sun, M Ji… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
We consider the problem of cache-aided Multiuser Private Information Retrieval (MuPIR)
which is an extension of the single-user cache-aided PIR problem to the case of multiple …

Unselfish coded caching can yield unbounded gains over selfish caching

F Brunero, P Elia - IEEE Transactions on Information Theory, 2022 - ieeexplore.ieee.org
The original coded caching scenario assumes a content library that is of interest to all
receiving users. In a realistic scenario though, the users may have diverging interests which …

Fundamental limits of demand-private coded caching

C Gurjarpadhye, J Ravi, S Kamath… - IEEE Transactions …, 2022 - ieeexplore.ieee.org
We consider the coded caching problem with an additional privacy constraint that a user
should not get any information about the demands of the other users. We first show that a …
