Topology-Aware Cooperative Data Protection in Blockchain-Based Decentralized Storage Networks
Siyi Yang, Ahmed Hareedy, Robert Calderbank +1
From currency to cloud storage systems, the continuous rise of the blockchain technology is moving various information systems towards decentralization. Blockchain-based decentrali…
Asymmetric LOCO Codes: Constrained Codes for Flash Memories
Ahmed Hareedy, Robert Calderbank
In data storage and data transmission, certain patterns are more likely to be subject to error when written (transmitted) onto the media. In magnetic recording systems with binary…
Hierarchical Coding to Enable Scalability and Flexibility in Heterogeneous Cloud Storage
Siyi Yang, Ahmed Hareedy, Robert Calderbank +1
In order to accommodate the ever-growing data from various, possibly independent, sources and the dynamic nature of data usage rates in practical applications, modern cloud data st…
Minimizing the Number of Detrimental Objects in Multi-Dimensional Graph-Based Codes
Ahmed Hareedy, Rohith Kuditipudi, Robert Calderbank
In order to meet the demands of data-hungry applications, data storage devices are required to be increasingly denser. Various sources of error appear with this increase in density…
LOCO Codes: Lexicographically-Ordered Constrained Codes
Ahmed Hareedy, Robert Calderbank
Line codes make it possible to mitigate interference, to prevent short pulses, and to generate streams of bipolar signals with no direct-current (DC) power content through balancin…
