Seamless application execution is vital for the usability of various delay-sensitive mobile
cloud applications. However, the resource-intensive migration process and intrinsic …

Background subtraction is a commonly used process in surveillance systems. One difficult
problem when using the process is maintaining a correct background image against …

Erasure coding is widely used for massive storage in data centers to achieve high fault
tolerance and low storage redundancy. Since the cross-rack communication cost is often …

We study a generalization of the setting of regenerating codes, motivated by applications to
storage systems consisting of clusters of storage nodes. There are n clusters in total, with m …

The paper is devoted to the problem of erasure coding in distributed storage. We consider a
model of storage that assumes that nodes are organized into equally sized groups, called …

Data centers increasingly adopt erasure coding to ensure fault-tolerant storage with low
redundancy, yet the hierarchical nature of data centers incurs substantial oversubscribed …

In the near future, the high volume of content together with new emerging and mission
critical applications is expected to stress the Internet to such a degree that it will possibly not …

This paper presents a flexible irregular model for heterogeneous cloud storage systems and
investigates how the cost of repairing failed nodes can be minimized. The fractional …

Distributed storage systems provide large-scale reliable data storage services by spreading
redundancy across a large group of storage nodes. In such big systems, node failures take …

We derive a lower bound on the amount of information accessed to repair failed nodes
within a single rack from any number of helper racks in the rack-aware storage model that …
