Coded Caching Clusters with Device-to-Device Communications
We consider a geographically constrained caching community where popular data files are cached on mobile terminals and distributed through Device-to-Device (D2D) communications. Further, to ensure availability, data files are protected against user mobility, or churn, with erasure coding. Communication and storage costs (in units of energy) are considered. We focus on finding the coding method ...
متن کاملDecentralized Caching and Coded Delivery with Distinct Cache Capacities
Decentralized proactive caching and coded delivery is studied in a content delivery network, where each user is equipped with a cache memory, not necessarily of equal capacity. Cache memories are filled in advance during the off-peak traffic period in a decentralized manner, i.e., without the knowledge of the number of active users, their identities, or their particular demands. User demands ar...
متن کاملOptimizing MDS Coded Caching in Wireless Networks with Device-to-Device Communication
We consider the caching of content in the mobile devices in a wireless network using maximum distance separable (MDS) codes. We focus on a small cell, served by a base station (BS), where mobile devices arrive and depart according to a Poisson birth-death process. Users requesting a particular file download coded symbols from caching devices using device-todevice communication. If additional sy...
متن کاملCache-induced Hierarchical Cooperation in Wireless Device-to-Device Caching Networks
We consider a wireless device-to-device (D2D) caching network where n nodes are placed on a regular grid of area A (n). Each node caches LCF (coded) bits from a library of size LF bits, where L is the number of files and F is the size of each file. Each node requests a file from the library independently according to a popularity distribution. Under a commonly used “physical model” and Zipf pop...
متن کاملCentralized Caching with Unequal Cache Sizes
We address centralized caching problem with unequal cache sizes. We consider a system with a server of files connected through a shared error-free link to a group of cacheenabled users where one subgroup has a larger cache size than the rest. We investigate caching schemes with uncoded cache placement which minimize the load of worst-case demands over the shared link. We propose a caching schem...
