Data management issues related to organizing and retrieving information from wireless channels have posed challenges for the database community. In this chapter, we discuss data dissemination to mobile clients and present solutions that address the bandwidth and energy limitations resulting from short battery life of the mobile units. We also add a subscription-based data access layer on top of this. Our solutions overall propose a secure and scalable wireless data dissemination architecture. Our broadcast organization and subscription-based access protocols are geared to work hand-in-hand to facilitate a complete content distribution solution via broadcasts.
