Guessing Facets: Polytope Structure and Improved LP Decoder
Alexandros G. Dimakis, Martin J. Wainwright
A new approach for decoding binary linear codes by solving a linear program (LP) over a relaxed codeword polytope was recently proposed by Feldman et al. In this paper we investiga…
Decentralized Erasure Codes for Distributed Networked Storage
Alexandros G. Dimakis, Vinod Prabhakaran, Kannan Ramchandran
We consider the problem of constructing an erasure code for storage over a network when the data sources are distributed. Specifically, we assume that there are n storage nodes wit…
Geographic Gossip: Efficient Aggregation for Sensor Networks
Alexandros G. Dimakis, Anand D. Sarwate, Martin J. Wainwright
Gossip algorithms for aggregation have recently received significant attention for sensor network applications because of their simplicity and robustness in noisy and uncertain env…
From Dumb Wireless Sensors to Smart Networks using Network Coding
A. G. Dimakis, D. Petrovic, K. Ramchandran
The vision of wireless sensor networks is one of a smart collection of tiny, dumb devices. These motes may be individually cheap, unintelligent, imprecise, and unreliable. Yet they…
