FemtoCaching: Wireless Video Content Delivery through Distributed Caching Helpers
Karthikeyan Shanmugam, Negin Golrezaei, Alexandros G. Dimakis +2
Video on-demand streaming from Internet-based servers is becoming one of the most important services offered by wireless networks today. In order to improve the area spectral effic…
Simple Regenerating Codes: Network Coding for Cloud Storage
Dimitris S. Papailiopoulos, Jianqiang Luo, Alexandros G. Dimakis +2
Network codes designed specifically for distributed storage systems have the potential to provide dramatically higher storage efficiency for the same availability. One main challen…
Distributed Storage Allocations for Optimal Delay
Derek Leong, Alexandros G. Dimakis, Tracey Ho
We examine the problem of creating an encoded distributed storage representation of a data object for a network of mobile storage nodes so as to achieve the optimal recovery delay.…
Distributed Storage Codes through Hadamard Designs
Dimitris S. Papailiopoulos, Alexandros G. Dimakis
In distributed storage systems that employ erasure coding, the issue of minimizing the total {\it repair bandwidth} required to exactly regenerate a storage node after a failure ar…
Repair Optimal Erasure Codes through Hadamard Designs
Dimitris S. Papailiopoulos, Alexandros G. Dimakis, Viveck R. Cadambe
In distributed storage systems that employ erasure coding, the issue of minimizing the total {\it communication} required to exactly rebuild a storage node after a failure arises.…
Reweighted LP Decoding for LDPC Codes
Amin Khajehnejad, Alexandros G. Dimakis, Babak Hassibi +2
We introduce a novel algorithm for decoding binary linear codes by linear programming. We build on the LP decoding algorithm of Feldman et al. and introduce a post-processing step…
