| Abstract: | This paper proposes a multi-version two-phase locking concurrency control protocol based on priority , which can be applied to the mobile real-time database .This protocol combines with the advantages of multi-version concurrency control mechanism and two-phase locking mechanism , introduces the concept of priority to classify the transactions and consider them with different situation .We perform simulation experiments to test the performance of this protocol and compare it with other related protocols .The results of experiments indicate that the protocol performs well as expected . |
