Scheduling on-demand broadcasts

Abstract

Assatellite,wirelessand CableW-based networksspreadtheir reach, there is an increased infrastructure of high-bandwidth links into the home and on the road. Much of this enhanced infrastructure inherently reties on bmdcast tuhnology to deliver data to large user populations. This increase in broadcast capacity has been complemented by the growth of large-scale infomtion-centn.c apptimtions. Many of these applications such as wireless interneta and traffic information systems are . pull-hosed, that is, they respond to on-denrarrd user requests.
