Driven by the explosive data traffic and new quality of service requirement of mobile users,
the communication industry has been experiencing a new evolution by means of network …

Video on-demand streaming from Internet-based servers is becoming one of the most
important services offered by wireless networks today. In order to improve the area spectral …

We propose a new scheme for increasing the throughput of video files in cellular
communications systems. This scheme exploits (1) the redundancy of user requests as well …

On-demand video streaming is becoming a killer application for wireless networks. Recent
information-theoretic results have shown that a combination of caching on the users' devices …

Caching at mobile devices can facilitate device-to-device (D2D) communications, which may
significantly improve spectrum efficiency and alleviate the heavy burden on backhaul links …

We analyze a novel architecture for caching popular video content to enable wireless device-
to-device (D2D) collaboration. We focus on the asymptotic scaling characteristics and show …

In this paper, we address the caching problem in small cell networks from a game theoretic
point of view. In particular, we formulate the caching problem as a many-to-many matching …

We introduce a novel wireless device-to-device (D2D) collaboration architecture that
exploits distributed storage of popular content to enable frequency reuse. We identify a …

We consider the design of a scheduling policy for video streaming in a wireless network
formed by several users and helpers (eg, base stations). In such networks, any user is …

This paper investigates the problem of proactive caching for multi-view 3D videos in the fifth
generation (5G) networks. We establish a mathematical model for this problem, and point …
