Abstract(in English) | Utilizing mobile devices as cache servers over 5G Device-to-Device(D2D) ad-hoc network is a promising technique to reduce explosive traffic generated from Video-on-Demand services. A challenge of D2D cache is to optimize this cache from a macroscopic view, but it has difficulty from the mismatch between the capricious nature of device mobility and the complexity of optimization. We partially overcome the complexity by Templatized Elastic Assignment (TEA) which utilizes templates for some typical optimization results and reuses them in different situations. Such templatization enables to determine the sub-optimal content allocation in the different number of devices with a few seconds of computation. %% However, TEA requires various patterns of "one-shot" calculation according to the request deviation, as this templatization depends on the request deviation. In this paper, we expand TEA to autonomously manage content allocation to closer to an ideal situation which is generated from estimation from the number of devices. %% Common characteristics of templates under different request deviation are heuristically modeled and verified to the perfect content aOur experiments show that the proposed scheme gives sub-optimal content allocation with only a few percents of traffic increase compared to a case of perfect content allocation. |
