“…In global Internet traffic, the contribution of video streaming is anticipated to be more than 80% by 2021 [24]. The streaming of high resolution 4k and 8k videos requires very high data rates and low latency [25]. Therefore, in near future, the exponentially growing popularity of video traffic will cause further increase in the data volume.…”

“…These popular items are cached before the arrival of content requests and utilized to serve the users during peak-hours. Caching mainly replaces additional bandwidth requirements by cheaper data storage units [25]. Therefore, cache-equipped networks reduce content delivery distance and avoid duplicate transmissions [33].…”

In recent years, the ever-increasing demand for networking resources and energy, fueled by the unprecedented upsurge in Internet traffic, has been a cause for concern for many service providers. Content caching, which serves user requests locally, is deemed to be an enabling technology in addressing the challenges offered by the phenomenal growth in Internet traffic. Conventionally, content caching is considered as a viable solution to alleviate the backhaul pressure. However, recently, many studies have reported energy cost reductions contributed by content caching in cache-equipped networks. The hypothesis is that caching shortens content delivery distance and eventually achieves significant reduction in transmission energy consumption. This has motivated us to conduct this study and in this article, a comprehensive survey of the state-of-the-art green caching techniques is provided. This review paper extensively discusses contributions of the existing studies on green caching. In addition, the study explores different cache-equipped network types, solution methods, and application scenarios. We categorically present that the optimal selection of the caching nodes, smart resource management, popular content selection, and renewable energy integration can substantially improve energy efficiency of the cache-equipped systems. In addition, based on the comprehensive analysis, we also highlight some potential research ideas relevant to green content caching.
