IDRC: A Distributed Real-Time Commit Protocol

摘要

With rapidly increasing interest in distributed real-time database systems (DRTDBS), data conflicts amongst distributed transactions have become a crucial factor which negatively influences the system performance. To address above issue, anImproved Data Lending based Distributed Real-Time Commit (IDRC) protocol has been developed. IDRC reduce the negative impact of data conflicts on the DRTDBSperformance by increasing the data accessibility as compared to the earlier protocols. It allows the commit dependent borrower participant node (who has already lent the data item to the abort dependent borrower participant node) to lend the same data item in read mode to more than one borrower participant nodes. The simulation results show that the proposed commit protocol outperforms.
