This paper investigates the content placement problem to maximize the cache hit ratio in
device-to-device (D2D) communications overlaying cellular networks. We consider …

In this work we consider the problem of optimal cache placement in a D2D enabled cellular
network. There are a number of helper devices in the area, which use their cached contents …

This paper studies the problem of optimal cache placement to maximize the offloading
probability in a device-to-device (D2D) enabled cellular network with small base stations …

In this paper, cache placement problem in cellular networks with device to device
communications (D2D) is addressed. D2D transmission allows cellular bandwidth reuse …

Abstract Device‐to‐device (D2D) communications have been viewed as a promising data
offloading solution in cellular networks because of the explosive growth of multimedia …

In cache enabled D2D communication networks, the cache space in a mobile terminal is
relatively small compared with the huge amounts of multimedia contents. As such, a strategy …

Caching content by users constitutes a promising solution to decrease the costly
transmissions with going through the base stations (BSs). To improve the performance of in …

To maximize offloading gain of cache-enabled device-to-device (D2D) communications,
content placement and delivery should be jointly designed. In this letter, we jointly optimize …

Content caching in the device-to-device (D2D) cellular networks can be utilized to improve
the content delivery efficiency and reduce traffic load of cellular networks. In such cache …

Abstract Device-to-device (D2D) communication has huge potential to offload ever
increasing cellular traffic. As a premise, devices should store as many popular contents as …
