摘要 研究了移动实时计算环境下更新分发的问题,提出了混合前向多版本数据广播方案,该方案在保证事务一致性的同时满足了数据和事务本身的定时约束,模拟实验表明该方案能够有效地降低事务错过率和提高数据流行性。 A new updated dissemination protocol called hybrid forward multi-versions 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. Simulation results show that HFMVB has better performance compared with existed updated dissemination protocols and is more appropriate for MRTCS.
