Optimal Content Placement for En-Route Web Caching [PDF]

, 2003
This paper studies the optimal placement of web files for en-route web caching. It is shown that existing placement policies are all solving restricted partial problems of the file placement problem, and therefore give only sub-optimal solutions.

Optimizing The Spatial Content Caching Distribution for Device-to-Device Communications

, 2016
We study the optimal geographic content placement problem for device-to-device (D2D) networks in which the content popularity follows the Zipf law. We consider a D2D caching model where the locations of the D2D users (caches) are modeled by a Poisson ...
