Current rateless codes coding schemes ignored the order recovery of packets. To cope with this problem, average delay and maximum memory consumption were proposed as performance indices to characterize the order recovery performance, then a coding scheme based on two stages coding was proposed to improve the order recovery performance. Encoding of the front k coded symbols is the first stage, w...

Chien Computer Science and Engineering Department University of California, San Diego {fuyeda, hxia, achien}@ucsd.edu September 9, 2004 Abstract We examine the properties and performance of LT Codes for use in a high performance distributed file system. Different variations to the algorithm were created to achieve key characteristics, such as speed and data re...

Over the past decade, rateless codes, i.e., digital fountain codes, have emerged as an efficient and robust solution for reliable data transmission over packet erasure networks and a particularly suitable one for multicasting and broadcasting applications where users may experience variable channel conditions and packet loss rates, such as mobile environments. Luby Transform (LT) and Raptor cod...

of “Secure Data Compression and Error Correcting Codes for Networks and Cloud Storage” by James Alan Kelley, Ph.D., Brown University, May 2015. We present several novel constructions—combining cryptography, error correcting codes (ECCs), and data compression—that find ready application in enhancing security and fault-tolerance in cloud storage. We demonstrate this by presenting a simple (yet no...

In this paper we propose a practical Random Network Coding (RNC) scheme for data distribution in a peer-to-peer (P2P) overlay network. The use of RNC incurs a significant computational cost that, till present, has limited its deployment in practical applications. In this study it is shown that RNC complexity can be lowered by using Luby Transform (LT) codes to pre-encode the data and by letting...
