Contrary to orthogonal multiple-access (OMA), non-orthogonal multiple-access (NOMA)
schemes can serve a pool of users without exploiting the scarce frequency or time domain …

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 …

We consider a basic cache network, in which a single server is connected to multiple users
via a shared bottleneck link. The server has a database of files (content). Each user has an …

Caching is a technique to reduce peak traffic rates by prefetching popular content into
memories at the end users. Conventionally, these memories are used to deliver requested …

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 …

Replicating or caching popular content in memories distributed across the network is a
technique to reduce peak network loads. Conventionally, the main performance gain of this …

Caching of popular content during off-peak hours is a strategy to reduce network loads
during peak hours. Recent work has shown significant benefits of designing such caching …

The landscape toward 5G wireless communication is currently unclear, and, despite the
efforts of academia and industry in evolving traditional cellular networks, the enabling …

We consider a basic content distribution scenario consisting of a single origin server
connected through a shared bottleneck link to a number of users each equipped with a …

The Internet of Vehicles (IoV) can offer safe and comfortable driving experience, by the
enhanced advantages of space–air–ground-integrated networks (SAGINs), ie, global …
