TLDR
The results show that significant caching gains can be achieved in practice; 8 to 10 times increase in the cache hit ratio from cache-aware recommendations, and an extra 2 times increase from caching optimization.Abstract:
Joint caching and recommendation has been recently proposed for increasing the efficiency of mobile edge caching. While previous works assume collaboration between mobile network operators and content providers (who control the recommendation systems), this might be challenging in today's economic ecosystem, with existing protocols and architectures. In this paper, we propose an approach that enables cache-aware recommendations without requiring a network and content provider collaboration. We leverage information provided publicly by the recommendation system, and build a system that provides cache-friendly and high-quality recommendations. We apply our approach to the YouTube service, and conduct measurements on YouTube video recommendations and experiments with video requests, to evaluate the potential gains in the cache hit ratio. Finally, we analytically study the problem of caching optimization under our approach. Our results show that significant caching gains can be achieved in practice; 8 to 10 times increase in the cache hit ratio from cache-aware recommendations, and an extra 2 times increase from caching optimization.read more

Caching Efficiency Maximization for Device-to-Device Communication Networks: A Recommend to Cache Approach
TL;DR: This work quantitatively investigates how recommendation can be applied to enhance the caching efficiency of D2D enabled wireless content caching networks and shows that the optimal recommendation and caching policies which jointly maximize the cache efficiency is NP-hard to compute.

EICache: A learning-based intelligent caching strategy in mobile edge computing
Bing Tang,Linyao Kang +1 more
TL;DR: In this paper, an intelligent caching strategy for MEC based on machine learning has been proposed, which considers the user's mobility and interest preferences, and it could predict user mobility using historical trajectory based on LSTM algorithm, and predict interest using Gradient Boosting Decision Tree (GBDT) method, to obtain the content of interest in advance, and then cache the content in advance on the neighboring edge node where the user is likely to go.
