A New Minimum Density RAID-6 Code With a Word Size of Eight

RAID-6 storage systems protect k disks of data with two parity disks so that the system of k + 2 disks may tolerate the failure of any two disks. Coding techniques for RAID-6 systems are varied, but an important class of techniques are those with minimum density, with an optimal...

A Tutorial on Reed-Solomon Coding for Fault-Tolerance in RAID-Like Systems

It is well-known that Reed-Solomon codes may be used to provide error correction for multiple failures in RAID-like systems. The coding technique itself, however, is not as well-known. To the coding theorist, this technique is a straightforward extension to a basic coding paradigm and needs no special mention. However, to...

A New MDS Erasur Erasure Code for RAID-6

The RAID-6 specification calls for a storage system with multiple storage devices to tolerate the failure of any two devices. Numerous erasure coding techniques have been developed that can implement RAID-6; however, each has limitations. This paper describes a new class of RAID-6 codes called the Liberation Codes. These codes...

Binomial Graph: A Scalable and Fault-Tolerant Logical Network Topology

The number of processors embedded in high performance computing platforms is growing daily to solve larger and more complex problems. The logical network topologies must also support the high degree of scalability in dynamic environments. This paper presents a scalable and fault tolerant topology called BinoMial Graph BMG. BMG provides...

Self-Healing Network for Scalable Fault Tolerant Runtime Environments

Scalable and fault tolerant runtime environments are needed to support and adapt to the underlying libraries and hardware which require a high degree of scalability in dynamic large-scale environments. This paper presents a Self-Healing Network SHN for supporting scalable and fault-tolerant runtime environments. The SHN is designed to support transmission...

Performance Evaluation of Distributed Computing Paradigms in Mobile Ad Hoc Sensor Networks

The emergence of mobile ad hoc sensor networks has brought new challenges to traditional network design. This paper focuses on the study at the application layer. In specific, it compares the performance of two distributed computing paradigms, the client/server-based paradigm and the mobile-agent-based paradigm, through mathematical modeling and simulation. The...

Optimal Itinerary Analysis for Mobile Agents in Ad Hoc Wireless Sensor Networks

One of the most important problems studied in any sensor network is data fusion. Client/server paradigm has been a commonly used computing model in traditional Distributed Sensor Networks DSNs. However, the deployment of Wireless Sensor Networks WSNs and its ad hoc nature have brought new challenges to the fusion task....
