Optimising Redundancy in Distributed Sensor Networks

Whether it be for environmental sensing or Internet of Things (IoT) applications, sensor networks are of growing use thanks to their large-scale sensing and distributed data storage abilities. However, when used in hazardous conditions and thus undergoing ...

Adaptive Receiver Design for High Speed Optical Communication

Ilter Ozkaya

Conventional input/output (IO) links consume power, independent of changes in the bandwidth demand by the system they are deployed in. As the system is designed to satisfy the peak bandwidth demand, most of the time the IO links are idle but still consumin ...

Practical erasure codes for storage systems: The study of entanglement codes, an approach that propagates redundancy to increase reliability and performance

Verónica del Carmen Estrada Galiñanes

This dissertation deals with the design of practical erasure codes for storage systems. Hardware and logical disk failures are a common source of system failures that may lead to data loss. Nevertheless, it is predicted that spinning disks would remain the ...

Reliability Analysis of Data Storage Systems

Vinodh Venkatesan

Modern data storage systems are extremely large and consist of several tens or hundreds of nodes. In such systems, node failures are daily events, and safeguarding data from them poses a serious design challenge. The focus of this thesis is on the data rel ...

Guaranteed recovery of a low-rank and joint-sparse matrix from incomplete and noisy measurements

Pierre Vandergheynst, Mohammad Golbabaee

Assume a multichannel data matrix, which due to the column-wise dependencies, has low-rank and joint-sparse representation. This matrix wont have many degrees of freedom. Enormous developments over the last decade in areas of compressed sensing and low-ran ...

Reliability of clustered vs. declustered replica placement in data storage systems

Rüdiger Urbanke, Christina Fragouli

The placement of replicas across storage nodes in a replication-based storage system is known to affect rebuild times and therefore system reliability. Earlier work has shown that, for a replication factor of two, the reliability is essentially unaffected ...

Effect of replica placement on the reliability of large scale data storage systems

Christina Fragouli, Vinodh Venkatesan, Xiao-Yu Hu, Robert Haas

Replication is a widely used method to protect large- scale data storage systems from data loss when storage nodes fail. It is well known that the placement of replicas of the different data blocks across the nodes affects the time to rebuild. Several syst ...

The complexity of reliable distributed storage

Ron Levy

Distributed storage systems based on commodity hardware have gained in popularity because they are cheaper, can be made more reliable and offer better scalability than centralized storage systems. However, implementing and managing such systems is more com ...
