Collaborative Coded Caching for Partially Connected Networks
Kagan Akcay, Eleftherios Lampiris, MohammadJavad Salehi +1
Coded caching leverages the differences in user cache memories to achieve gains that scale with the total cache size, alleviating network congestion due to high-quality content req…
Adapt or Wait: Quality Adaptation for Cache-aided Channels
Eleftherios Lampiris, Giuseppe Caire
This work focuses on quality adaptation as a means to counter the effects of channel degradation in wireless, cache-aided channels. We design a delivery scheme which combines coded…
Multi-Transmitter Coded Caching Networks with Transmitter-side Knowledge of File Popularity
Eleftherios Lampiris, Berksan Serbetci, Thrasyvoulos Spyropoulos +2
This work presents a new way of exploiting non-uniform file popularity in coded caching networks. Focusing on a fully-connected fully-interfering wireless setting with multiple cac…
Fundamental Limits of Wireless Caching Under Mixed Cacheable and Uncacheable Traffic
Hamdi Joudeh, Eleftherios Lampiris, Petros Elia +1
We consider cache-aided wireless communication scenarios where each user requests both a file from an a-priori generated cacheable library (referred to as 'content'), and an uncach…
Fundamental Limits of Wireless Caching under Uneven-Capacity Channels
Eleftherios Lampiris, Jingjing Zhang, Osvaldo Simeone +1
This work identifies the fundamental limits of cache-aided coded multicasting in the presence of the well-known `worst-user' bottleneck. This stems from the presence of receiving u…
Wyner's Network on Caches: Combining Receiver Caching with a Flexible Backhaul
Eleftherios Lampiris, Aly El Gamal, Petros Elia
In this work, we study a large linear interference network with an equal number of transmitters and receivers, where each transmitter is connected to two subsequent receivers. Each…
Resolving the Feedback Bottleneck of Multi-Antenna Coded Caching
Eleftherios Lampiris, Antonio Bazco-Nogueras, Petros Elia
Multi-antenna cache-aided wireless networks have been known to suffer from a severe feedback bottleneck, where achieving the maximal Degrees-of-Freedom (DoF) performance required f…
Full Coded Caching Gains for Cache-less Users
Eleftherios Lampiris, Petros Elia
Within the context of coded caching, the work reveals the interesting connection between having multiple transmitters and having heterogeneity in the cache sizes of the receivers.…
Coded Distributed Computing with Node Cooperation Substantially Increases Speedup Factors
Emanuele Parrinello, Eleftherios Lampiris, Petros Elia
This work explores a distributed computing setting where nodes are assigned fractions (subtasks) of a computational task in order to perform the computation in parallel. In thi…
Adding transmitters dramatically boosts coded-caching gains for finite file sizes
Eleftherios Lampiris, Petros Elia
In the context of coded caching in the -user BC, our work reveals the surprising fact that having multiple () transmitting antennas, dramatically ameliorates the long-standin…
