Abstract: In this paper, we present a validation-based concurrency control protocol. The basic idea of the new protocol is to enhance the performance of real-time concurrency control mechanisms by reducing the number of transactions that miss their deadlines. Finally, we analyze the performance of this protocol by simulation.
