Using Predeclaration for Efficient Read-only Transaction Processing in Wireless Data Broadcast

Wireless data broadcast allows a large number of users to retrieve data simultaneously in mobile databases, resulting in an efficient way of using the scarce wireless bandwidth. However, the efficiency of data access methods is limited by an inherent property that data can only be accessed strictly sequentially by users. To properly cope with the inherent property, this paper presents three predeclaration-based transaction processing methods that yield a significant performance improvement in wireless data broadcast.
