B Zolfaghari, V Singh, BK Rai, K Bibak, T Koshiba - Entropy, 2021 - mdpi.com
The idea behind network caching is to reduce network traffic during peak hours via
transmitting frequently-requested content items to end users during off-peak hours …

Probabilistic caching based on maximum distance separable code in a user-centric clustered cache-aided wireless network

D Ko, B Hong, W Choi - IEEE Transactions on Wireless …, 2019 - ieeexplore.ieee.org
We investigate how the maximum-distance separable (MDS) coding can be incorporated
into probabilistic caching to utilize the limited storage space efficiently. In a user-centric …
