Recent studies on transaction processing in broadcast environments have an implicit assumption that the server is able to broadcast consistent data to the mobile clients. However, this assumption may not be valid unless there is a special algorithm to handle broadcasting data in a consistent and timely manner. To our best knowledge, there is no related work on this problem yet. In this work, we devise an efficient algorithm that causes least interference with the update transactions to read the entire database for broadcasting at the server. Our future work is to develop a complete framework for scheduling the broadcast transaction to meet the objectives: to read the entire database consistently with minimum impact to the system, to broadcast fresh data, and to meet the time constraint imposed by the periodicity of broadcast cycle.
