In this paper, we give the first constant-approximations for a number of layered network design problems. We begin by modeling hierarchical caching, where caches are placed in la...
The multipass-rendering method integrating radiosity with ray-tracing gives one of the best solutions for synthesizing photo-realistic images. However, the method is also computat...
Web-based collaboration systems typically require dynamic and context-based interactions between people and services. To support such complex interaction scenarios, we introduce a...
ABSTRACT Because of technology advances power consumption has emerged up as an important design issue in modern high-performance microprocessors. As a consequence, research on redu...

Future computer networks are expected to carry bursty traffic. Shortest -path routing protocols such as OSPF and RIP have t he disadvantage of causing bottlenecks due to their inh...
