Abstract
Serializable concurrency control protocols are inapplicable in mobile broadcast environments due to a number of constraints of wireless communications and characteristics of mobile real time applications.In this paper,the use of hypo-serializability for mobile parallel broadcast environments is proposed.At first,hypo-serializability is formally defined.Next,it is proved that hypo-serializability is more relaxing than traditional serializability while consistency is maintained all the time.Then,the necessary and sufficient conditions for hypo-serializability are shown.Furthermore,the parallel hypo-serializable concurrency control protocol BCC-HSR is proposed.Finally,through a series of simulation studies,it is confirmed that the proposed protocol could improve average response time of mobile transactions significantly.
