摘要：
With the rapid advances in mobile computing technology, there is an increasing demand for various mobile applications to process transaction in a real-time fashion. Owing to the intrinsic characteristics of mobile computing systems, such as high delay of network, frequent disconnection and mobility etc, it is very difficult to meet transaction deadlines in a mobile environment by using traditional transaction processing technology. This paper proposes a hybrid optimistic real-time transaction concurrency control method based on high priority two phase locking scheme (HORTCC-SHP2PL). The HORTCC -SHP2PL combines optimistic concurrency control with high priority two-phase locking in mobile real-time transaction processing and utilizes two-phase commit protocol for global commitment of mobile real-time transaction. In order to further reduce the number of mobile real-time transaction restarts, we introduce the notion of similarity in concurrency control.
