Device-to-device (D2D) communication is a promising supplement to cellular networks,
since it provides high rate transmission without changing network infrastructure. For a D2D …

In next-generation LTE-advanced cellular networks, device-to-device (D2D) communication
has emerged as an effective way to offload cellular traffic and improve system performance …

In this paper, the problem of content caching in 5G cellular networks relying on social-aware
device-to-device communications (DTD) is investigated. Our focus is on how to efficiently …

Device-to-device (D2D) content sharing helps to accommodate the exponentially surge in
mobile data traffic. However, how to cache in mobile users is crucial to ensure the above …

Mobile video traffic and mobile devices have now outpaced other data traffic and fixed
devices. Global service providers are attempting to propose new mobile infrastructures and …

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 …

D2D content sharing is recognized as an effective response to the prevalence of multimedia
and local services, especially for 5G edge networks. We construct a content sharing …

Cache-enabled device-to-device (D2D) communications can boost network throughput. By
pre-downloading contents to local caches of users, the content requested by a user can be …

We consider a mobile content delivery network (mCDN) in which special mobile devices
designated as caching servers (caching-server device: CSD) can provide mobile stations …
