Mobile real-time read-only transaction processing in data broadcast environments

Data broadcast is a widely accepted data dissemination method for mobile computing systems. When data broadcast is used to deliver frequently updated data to mobile read-only transactions, we call it updates dissemination. Existed updates dissemination protocols are unsuitable for mobile real-time read-only transaction processing since they neglect the time constraints on both data and transactions. In this paper a new updates dissemination protocol called hybrid forward multi-version data broadcast (HFMVB) is proposed. HFMVB not only guarantees the consistency of read-only transactions, it also provides higher data currency and lower miss rate by shortening the consistency interval, instantly broadcasting updates and making use of broadcast on-demand.
