Coded Caching for Time-Varying Files Popularities and Asynchronous Delivery
IEEE Open Journal of the Communications Society, 2021 Data communication has seen exponential growth recently, and it currently dominates wireless communication. As a result, proactive caching was developed to minimize peak traffic rates by storing content, in advance, at different nodes in the network.

Multi-library coded caching [PDF]
2016 54th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2016 We study the problem of coded caching when the server has access to several libraries and each user makes independent requests from every library. The single-library scenario has been well studied and it has been proved that coded caching can significantly improve the delivery rate compared to uncoded caching.

Weakly Secure Coded Caching Scheme for an Eavesdropper Having Prior Knowledge
IEEE Access, 2020 Coded caching is a promising method for solving caching problems in content-centric wireless networks. To enhance the security of coded caching for practical purposes, this paper investigates a secure coded caching scheme for defending against an ...

Multi-antenna coded caching [PDF]
2017 IEEE International Symposium on Information Theory (ISIT), 2017 In this paper we consider a single-cell downlink scenario where a multiple-antenna base station delivers contents to multiple cache-enabled user terminals. Based on the multicasting opportunities provided by the so-called Coded Caching technique, we investigate three delivery approaches. Our baseline scheme employs the coded caching technique on top of

Device-to-Device Coded-Caching With Distinct Cache Sizes [PDF]
IEEE Transactions on Communications, 2020 This paper considers a cache-aided device-to-device (D2D) system where the users are equipped with cache memories of different size. During low traffic hours, a server places content in the users' cache memories, knowing that the files requested by the users during peak traffic hours will have to be delivered by D2D transmissions only.

XRootD and Object Store: A new paradigm [PDF]
EPJ Web of Conferences, 2020 The XRootD software framework is essential for data access at WLCG sites. The WLCG community is exploring and expanding XRootD functionality. This presents a particular challenge at the RAL Tier-1 as the Echo storage service is a Ceph based Erasure Coded

Coding for Caches in the Plane
CoRR, 2013 We consider wireless caches located in the plane according to general point process and specialize the results for the homogeneous Poisson process. A large data file is stored at the caches, which have limited storage capabilities. Hence, they can only store parts of the data. Clients can contact the caches to retrieve the data. We compare the expected

Multi-level coded caching [PDF]
2014 IEEE International Symposium on Information Theory, 2014 Recent work has demonstrated that for content caching, joint design of storage and delivery can yield significant benefits over conventional caching approaches. This is based on storing content in the caches, so as to create coded-multicast opportunities even amongst users with different demands.

On the Performance of the Cache Coding Protocol [PDF]
Information, 2018 Network coding approaches typically consider an unrestricted recoding of coded packets in the relay nodes for increased performance. However, this can expose the system to pollution attacks that cannot be detected during transmission, until the receivers attempt to recover the data.
