Abstract: A new updated dissemination protocol called hybrid forward multi-versions data broadcast (HFMVB) is proposed. HFMVB not onlyguarantees the consistency of read-only transactions, it also provides higher data currency and lower miss rate. Simulation results show that HFMVBhas better performance compared with existed updated dissemination protocols and is more appropriate for MRTCS.
