WebDec 1, 2024 · A costoptimal caching problem (COCP) for device-to- device (D2D) networks is formulated, in which the impact of user mobility, cache size, and total number of encoded file segments are considered. Caching popular files at user equipments (UEs) provides an effective way to alleviate the burden of the backhaul networks. WebJan 1, 2024 · When the optimal policy fetches a missed request, it must not load the fetched data into the cache and trigger evictions, because otherwise prefetching will be a better option. Therefore, it is sufficient to consider the policies such that data items will only be loaded into the cache by prefetching. dutch bros brookings oregon
