Coded Caching Clusters with Device-to-Device Communications
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. To ensure availability, data files are protected against user mobility, or churn, with select caching and erasure coding methods. Communication and storage costs are considered, with an objective …
