To support various bandwidth requirements for mobile multimedia services for future heterogeneous mobile environments, a transcoding video proxy is usually necessary to provide ad...
In this paper, we introduce Z-Ring, a fast prefix routing protocol for peer-to-peer overlay networks. Z-Ring incorporates cost-efficient membership protocol to achieve fast routin...

In this paper, we propose four architectures for intrusion-tolerant database systems. While traditional secure database systems rely on prevention controls, an intrusion-tolerant ...
Many “ubiquitous computing” applications need a constant flow of information about their environment to be able to adapt to their changing context. To support these “contex...
