Abstract

In a mobile computing environment, users can perform on-line transaction processing independent of their physical location. In a mobile environment, multiple mobile hosts may update the data simultaneously which may result in inconsistency of data. To solve such problems many concurrency control techniques have been proposed. The traditional two phase locking protocol has some inherent problems such as deadlocks & long unpredictable blocking. In this paper we propose a concurrency control mechanism with dynamic timer adjustment which helps in reducing the communication overhead and enhances the transaction throughput. The simulation results specify the performance trade off metrics.
