Quorum Placement on Wide-Area Networks

Content distribution networks are the dominant technology for distributing shared media on todays Internet. There are several types of content for which these systems have been proven highly successful: static databases, streaming media, online gaming. At the same time this architecture is not appropriate for other types of applications such as transactional databases that require both strong c...

A Secure Routing Algorithm for Underwater Wireless Sensor Networks

Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...

Secure & agile wide-area virtual machine mobility

Global Information Grid (GIG) operations would benefit greatly from improved support for virtual machines (VMs) that can migrate not only between physical devices within a datacentre, but also between physical devices located on different continents, while maintaining their existing IP communications sessions. Such VM migration can enable improvements with: CPU load-balancing, network traffic-e...

Support for Object Placement in Wide Area Heterogeneous Distributed Systems

One of the open challenges in distributed computing systems is determining how to place tasks onto processors when they are needed (in the Legion project being developed at UVA the basic computational units are modelled as objects, so the problem is one of object placement). The placement decision is crucial because it determines the run-time behavior of an object, including performance, cost a...
