A Mobile Real-Time Transaction Scheduling Strategy

Supporting disconnection and improving the transaction success rate are two important issues of real-time transaction processing in mobile computing environments. In this paper, a method of assigning priority which takes network disconnection into account is given first. Then a definition of Epsilon Conflict Transaction which reduces the possibility of transaction conflicts is given. Finally we give a transaction scheduling strategy of avoiding conflicts,which integrates transaction scheduling and concurrency control, reduces the overhead of transaction managements,and improves the transaction success rate.
