The edge cache is an effective way to reduce the heavy traffic load and the end-to-end
latency in radio access networks (RANs) for supporting a number of critical Internet of Things …

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 …

This paper aims to provide an optimization framework for coded caching that accounts for
various heterogeneous aspects of practical systems. An optimization theoretic perspective …

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, there …

Degraded K-user broadcast channels (BCs) are studied when the receivers are facilitated
with cache memories. Lower and upper bounds are derived on the capacity-memory …

Cache-aided content delivery is studied in a multi-server system with P servers and K users,
each equipped with a local cache memory. In the delivery phase, each user connects …

Cache-aided coded content delivery is studied for devices with diverse quality-of-service
requirements, specified by a different average distortion target. The network consists of a …

Joint optimal resource allocation and probabilistic caching design is conceived for device-to-
device (D2D) communications in a heterogeneous wireless network (HetNet) relying on full …

A cache-aided broadcast network is studied, in which a server delivers contents to a group
of receivers over a packet erasure broadcast channel. The receivers are divided into two …

The centralized coded caching problem is studied for the two-user scenario, considering
heterogeneous cache capacities at the users and private channels from the server to the …
