The diversity of data sources and Web services currently available on the Internet. In this paper, the authors develop a framework for comparing pull based solutions and present dual optimization approaches. The first approach maximizes user utility while satisfying constraints on the usage of system resources. The second approach satisfies the utility of user profiles while minimizing the usage of system resources. They present a optimal solution (SUP) for the latter approach and formally identify sufficient conditions for SUP to be optimal for both. In their paper provide solutions to pull-based delivery that they cannot adapt to the dynamic behavior of wide area applications.
