Abstract |
With the rapid growth in watching videos from mobile devices, hierarchical caching servers are widely deployed in wireless networks to improve the experience of mobile clients. We propose a novel caching hierarchy with cross-layer cooperations to reduce the video redundancy in traditional inclusive cache hierarchy (ICH). With the help of low-layer caches, the high-layer cache in our proposed cooperated cache hierarchy (CCH) is able to calculate the profit of caching each video in its space and make cache decision that brings the highest performance improvement. Simulations show that our CCH outperforms ICH under all cache sizes. Index Terms- Video Caching, Cooperation, Wireless Network | |||||||||
