Content Caching Utilizing Scalable Video Coding (SVC) in Wireless Edge Networks

It is possible to enhance video streaming efficiency and lessen the stress on origin servers by prefetching well-liked videos into the local caches of edge nodes. Scalable Video Coding (SVC) is a video coding standard that allows a video stream to be encoded into multiple layers or “scalability layers,” each providing a different level of video quality and bit rate. This makes it possible to adapt the video stream to different network conditions and device capabilities. Integrating SV C with edge caching can provide several benefits for video streaming. By storing multiple scalability layers in the edge cache, the video stream can be adapted to the network conditions and device capabilities of the end-user. Furthermore, by caching multiple scalability layers, the edge cache can provide more granular control over the video quality delivered to end-users. In this study, we talk about the difficulties that come with scaled videos unique watching requirements and varying content popularity. We give a brief review of the current caching strategies and list the factors to consider when choosing a caching strategy. After that, a case study is presented in which the transmission latency is measured as a performance parameter. In comparison to the current caching systems running without SV C, simulation findings show that taking into account the practical requirements of end users can drastically reduce the content transmission delay.
