Abstract
Data broadcasting in wireless information services is a very effective technique to disseminate information to a massive number of clients when the number of data items is small. When the number of items is large, however, it may be beneficial to integrate a client-to-server backchannel with the push-based data broadcast approach, resulting in a hybrid data delivery. In this paper, the performance behavior of a predeclaration-based transaction processing in mobile data broadcast environments is examined. The extensive simulation studies have been performed to evaluate the effectiveness of our methods not only in a pure push data delivery but also in the hybrid data delivery. The analysis of simulation results has shown that the use of predeclaration-based transaction processing can provide significant performance improvement in mobile data broadcast environments.
