DOI: 10.1007/s11277-019-06369-z
Abstract: AbstractDecentralized hierarchical coded caching is studied with two layers of caches which users receive their demands through intermediate helpers from a main server. Coded caching in hierarchical model reduces rates in both layers and this… read more here.

DOI: 10.1109/access.2020.3042849
Abstract: Coded caching schemes with low subpacketization and small transmission rate are desirable in practice due to the requirement of low implementation complexity and efficiency of transmission. Placement delivery arrays (PDA in short) can be used… read more here.

DOI: 10.1109/lcomm.2022.3184765
Abstract: This letter studies coded caching with file and demand privacy (f&d-privacy) which guarantees that each user learns no information neither about other users’ demands, nor about non-demanded files. First, we prove that an f&d-private coded… read more here.

DOI: 10.1109/lwc.2020.2975661
Abstract: We study coded caching over non-ergodic fading channels. As the multicast capacity of a broadcast channel is restricted by the user experiencing the worst channel conditions, we formulate an optimization problem to minimize the transmission… read more here.
