A Construction Framework of Coded Caching Scheme for Multi-Access MISO Systems via Knapsack Problem
Siying Luo, Youlong Wu, Mingming Zhang +2
This paper investigates the coded caching problem in a multi-access multiple-input single-output (MAMISO) network with the combinatorial topology. The considered system consists of…
Rack-Aware MSR Codes with Linear Field Size and Smaller Sub-Packetization for Tolerating Multiple Erasures
Hengming Zhao, Dianhua Wu, Minquan Cheng
In an rack-aware storage model, the system consists of nodes uniformly distributed across successive racks, such that each rack contains nodes of equal…
Explicit Constructions for Rack-Aware Minimum Storage Partially Cooperative Regenerating Codes
Hengming Zhao, Dianhua Wu, Minquan Cheng
The rack-aware storage model improves repair efficiency by exploiting locality within racks to minimize cross-rack traffic in a distributed storage system. While the partially coop…
On balanced difference packings
Hengming Zhao, Rongcun Qin, Dianhua Wu
Let be a set of positive integers and let be an additive group. A difference packing is a set of subsets of with sizes from whose list of differences co…
