This paper proposes a new commit protocol for real time distributed database systems, Dependency Sensitive Shadow SWIFT (DSS-SWIFT) protocol where the cohort forks off a replica of itself called a shadow, whenever it borrows dirty value of a data item, and if, the created dependency is abort type as compared to creating shadow in all cases of dependency in Shadow PROMPT [3]. Also the health factor of cohort is used for permitting to use dirty value of lender rather than health factor of transaction as whole. The performance of DSS-SWIFT is compared with PROMPT, 2SC [6] and SWIFT [7] protocols for both main memory resident and disk resident databases with and without communication delay. Simulation results show that the proposed protocol improves the system performance up to 7 % as transaction miss percentage.
