This paper investigates learning-based caching in small-cell networks (SCNs) when user
preference is unknown. The goal is to optimize the cache placement in each small base …

The next evolutionary step in human-computer interfaces will bring forward immersive digital
experiences that submerge users in a 3D world while allowing them to interact with virtual or …

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 …

Human-computer interaction continuously evolves towards a genuinely immersive
experience, submerging users in a three-dimensional (3D) virtual world. A realistic …

The idea behind network caching is to reduce network traffic during peak hours via
transmitting frequently-requested content items to end users during off-peak hours …

Immersive viewing is emerging as the next interface evolution for human-computer
interaction. A truly wireless immersive application necessitates immense data delivery with …

In traditional cache-enabled small-cell networks (SCNs), a user can suffer strong
interference due to content-centric base station association. This may degenerate the …

We address the worst-user bottleneck of wireless coded caching, which is known to severely
diminish cache-aided multicasting gains due to the fundamental worst-channel limitation of …

We investigate the use of coded caching in the single-cell downlink scenario where the
receiving users are randomly located inside the cell. We first show that, as a result of having …

The proliferation of portable camera devices, represented by smartphones, is increasing the
risk of sensitive internal data being leaked by screen shooting. To trace the leak source, a lot …
