Abstract

Blockchain-based edge caching technology supports edge devices from different operators to share content, improves the efficiency of cached content usage, and reduces network operation and deployment costs. However, different operators build their own edge devices and the cached contents are isolated and have difficulty in sharing information. Aiming at this problem, this paper improved the architecture of an edge cache system based on consortium chain, so that the edge devices deployed by different operators can break the content isolation and achieve a wider range of content sharing. In order to improve the operator cache revenue while ensuring the user transmission quality and reducing the user transmission delay, this article first analyzes the impact of different content delivery methods on user transmission delay and operator caching benefits in terms of cache popularity, content size, and edge device collaboration capabilities. Then, an optimization problem was established with the goal of maximizing the cache benefit and minimizing the transmission delay. Finally, to solve the proposed high-dimensional large-scale caching decision problem, asynchronous advantage actor-critic (A3C) based content caching algorithm was used to determine optimal placement of content. Simulation results show that the proposed cache strategy can effectively enhance the revenue of edge caching, reduce the delay of content delivery and improve the user experience.
