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. The efficiency of data access methods, however, is limited by an inherent property that data can only be accessed strictly sequentially by users. The paper addresses the issue of ensuring consistency and currency of data items requested in a certain order by wireless read-only transactions. To properly cope with the inherent property of data broadcast, we explore a predeclaration-based query optimization and devise three predeclaration-based transaction processing methods.
