An Updates Dissemination Protocol for Read-Only Transaction Processing in Mobile Real-Time Computing Environments

Data management issues in mobile computing environments have got lots of concerns of relevant researchers. Among these research topics, data broadcast has been extensively investigated due to its advantages such as scalability and bandwidth effectiveness. While plenty of works have been done on this subject, it is still less touched when data broadcast is used to deliver constantly updated real-time data to read-only transactions with deadlines. In this paper, we first deeply analyze the data dissemination requirements for readonly transaction processing in mobile real-time computing environments and formally define several performance objectives. Then a novel updates dissemination protocol called mixed real-time data broadcast is proposed. In mixed real-time data broadcast, a set of new techniques including reducing the length of consistency intervals, immediate updates dissemination policy and ondemand data delivery are incorporated seamlessly. Moreover, an enhanced index structure i...
