We consider a mobile user accessing contents in a dynamic environment, where new
contents are generated over time (by the user's contacts) and remain relevant to the user for …

Pushing along with proactive caching, in which content items are transmitted prior to being
requested by a user, holds the promise of trading scalable storage resources for substantial …

Caching at the base stations (BSs) has been widely adopted to reduce the delivery delay
and alleviate the backhaul traffic between BSs and the core network. In this paper, we …

Content caching at the base stations (BSs) is a promising strategy that can provide improved
quality-of-service (QoS) provisioning for content-centric services, and at the same time …

By pushing popular contents directly to users through broadcast networks while serving
individual requests using cellular networks, a wireless converged network provides a highly …

Multicasting can reduce network traffic in multiuser systems by serving multiple users
simultaneously. The benefits of multicasting basically come from the overlapping and …

Proactively pushing content to users has emerged as a promising technology to cope with
the explosively growing traffic demands of next-generation mobile networks. Yet, it is unclear …

For content-centric wireless networks, pushing and proactive caching hold the promise of
greatly improving system throughput in the future. However, the throughput gains obtained …

Caching popular contents at mobile devices can potentially improve the quality of service for
mobile users and relieve traffic burden of base station in cellular networks. In this paper, we …

Proactively pushing content to users is a promising way of coping with the explosively
growing traffic demand of next-generation mobile networks. However, it is unclear whether …
