Caching Efficiency Maximization for Device-to-Device Communication Networks: A Recommend to Cache Approach

Yaru Fu et al.

Summary: Edge side caching assisted D2D communication is a promising technique to reduce network latency and backhaul transmission burden. However, the effectiveness of caching strategies at the network edge depends on individual user's content preference distribution. Recommendation plays a crucial role in reshaping content request probabilities, impacting cache decisions significantly. Our research investigates how recommendation can enhance caching efficiency in D2D enabled wireless content caching networks, optimizing cache hit ratio and demonstrating the potential for sub-optimal algorithms.
