Fundamental limits of caching in wireless D2D networks

M Ji, G Caire, AF Molisch - IEEE Transactions on Information …, 2015 - ieeexplore.ieee.org
We consider a wireless device-to-device (D2D) network where communication is restricted
to be single-hop. Users make arbitrary requests from a finite library of files and have pre …

Order-optimal rate of caching and coded multicasting with random demands

M Ji, AM Tulino, J Llorca, G Caire - IEEE Transactions on …, 2017 - ieeexplore.ieee.org
We consider the canonical shared link caching network formed by a source node, hosting a
library of m information messages (files), connected via a noiseless multicast link to n user …

Coded caching under arbitrary popularity distributions

J Zhang, X Lin, X Wang - IEEE Transactions on Information …, 2017 - ieeexplore.ieee.org
Caching plays an important role in reducing the backbone traffic when serving high-volume

Adding transmitters dramatically boosts coded-caching gains for finite file sizes

E Lampiris, P Elia - IEEE Journal on Selected Areas in …, 2018 - ieeexplore.ieee.org
In the context of coded caching in the K-user broadcast channel, our work reveals the
surprising fact that having multiple (L) transmitting antennas, dramatically ameliorates the …

Finite-length analysis of caching-aided coded multicasting

K Shanmugam, M Ji, AM Tulino… - IEEE Transactions …, 2016 - ieeexplore.ieee.org
We study a noiseless broadcast link serving K users whose requests arise from a library of N
files. Every user is equipped with a cache of size M files each. It has been shown that by …

Fundamental limits of coded caching with multiple antennas, shared caches and uncoded prefetching

E Parrinello, A Ünsal, P Elia - IEEE Transactions on Information …, 2019 - ieeexplore.ieee.org
The work explores the fundamental limits of coded caching in the setting where a transmitter
with potentially multiple (N 0) antennas serves different users that are assisted by a smaller …

Fog-aided wireless networks for content delivery: Fundamental latency tradeoffs

A Sengupta, R Tandon… - IEEE Transactions on …, 2017 - ieeexplore.ieee.org
A fog-aided wireless network architecture is studied in which edge nodes (ENs), such as
base stations, are connected to a cloud processor via dedicated fronthaul links while also …

Coded caching with linear subpacketization is possible using Ruzsa-Szeméredi graphs

K Shanmugam, AM Tulino… - 2017 IEEE International …, 2017 - ieeexplore.ieee.org
