COR-Based Concurrency Control Strategies in Functional Alternative Real-Time Transaction Model

This paper present a Functional Alternatives Transaction Model (short for FATM), which provides multiple execution path for the important transactions. Based on FATM, we divide the alternative into multiple Critical Operation Region (short for COR). After that we analyze and propose the strategies that can improve the concurrence of the alternatives. The performance of our method is evaluated via simulation experiments, and the results show that the proposed method is efficient and can effectively improve the concurrence of the transactions, and hence increase the successful execution ratio of the transactions.
