We address the issue of ensuring consistency of multiple data items requested in a certain order by read-only transactions in wireless data broadcast. To handle the inherent property in a data broadcast environment that data can only be accessed strictly sequential by users, we explore a predeclaration-based query optimization and devise two practical transaction processing methods in the context of local caching. We also evaluate the performance of the proposed methods by an analytical study. Evaluation results show that the predeclaration technique we introduce reduces response time significantly and adapts to dynamic changes in workload
