Device-to-Device Coded Caching with Distinct Cache Sizes
Abdelrahman M. Ibrahim, Ahmed A. Zewail, Aylin Yener
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 conte…
Benefits of Coded Placement for Networks with Heterogeneous Cache Sizes
Abdelrahman M. Ibrahim, Ahmed A. Zewail, Aylin Yener
In this work, we study coded placement in caching systems where the users have unequal cache sizes and demonstrate its performance advantage. In particular, we propose a caching sc…
Coded Caching for Heterogeneous Systems: An Optimization Perspective
Abdelrahman M. Ibrahim, Ahmed A. Zewail, Aylin Yener
In cache-aided networks, the server populates the cache memories at the users during low-traffic periods, in order to reduce the delivery load during peak-traffic hours. In turn, t…
Device-to-Device Secure Coded Caching
Ahmed A. Zewail, Aylin Yener
This paper studies device to device (D2D) coded-caching with information theoretic security guarantees. A broadcast network consisting of a server, which has a library of files, an…
On Coded Caching with Heterogeneous Distortion Requirements
Abdelrahman M. Ibrahim, Ahmed A. Zewail, Aylin Yener
This paper considers heterogeneous coded caching where the users have unequal distortion requirements. The server is connected to the users via an error-free multicast link and des…
Combination Networks with or without Secrecy Constraints: The Impact of Caching Relays
Ahmed A. Zewail, Aylin Yener
This paper considers a two-hop network architecture known as a combination network, where a layer of relay nodes connects a server to a set of end users. In particular, a new model…
