We propose a color-based distributed and cooperative cache control scheme. The proposed scheme assigns color-based tags to each cache server as well as each content.
We also propose a template-based sub-optimal content distribution, which is called templatized elastic assignment (TEA) scheme, for device to device (D2D) content sharing networks. The proposed TEA scheme minimizes communication traffic volume via base stations using parameters such as the number of mobile devices and content access popularity.
We developed a prototype of content delivery network (CDN) to examine effectiveness of our proposals. Based on our evaluation, up to 92% of traffic volume on CDN is reduced compared to a case without using the proposed cache system.
