The growing importance of Web traffic on the Internet makes it important that we have accurate traffic models in order to plan and provision. In this paper we present a Web traffic model designed to assist in the evaluation and engineering of shared communications networks. Because the model is behavioral we can extrapolate the model to assess the effect of(More)
A revolution is occurring in the scope and range of information, communication and education services that will be made available to schools, libraries, town-halls, clinics and, most importantly, residences.

he ability to communicate with anyone on the planet from anywhere on the planet has been mankind's dream for a long time. Wireless is the only medium that can enable such untethered communication. With the recent advances in VLSI and wireless technologies, it is now possible to build high-speed wireless systems that are cheap as well as easy to install and(More)
