Optimal caching placement for D2D assisted wireless caching networks
TL;DR: The placement problem for the helper-tier caching network is reduced to a convex problem, and can be effectively solved by the classical water-filling method, and notices that users and helpers prefer to cache popular contents under low node density and prefer to caches different contents evenly under high node density.

Exploiting user mobility for D2D assisted wireless caching networks
Jun Rao,Hao Feng,Zhiyong Chen +2 more
TL;DR: It is found that the mobility of user not only provides mobility gain, but also improves computation gain as the proposed scheme achieves both mobility gain and computation gain, by increasing caching efficiency and distributing content across users caches.

Optimal Caching Placement for D2D Assisted Wireless Caching Networks
TL;DR: In this article, the optimal caching placement to maximize the offloading probability for a two-tier wireless caching system, where the helpers and a part of users have caching ability, was devised.
