Abstract

The inherent limitations of mobile database systems makes concurrency control an important problem. Several pessimistic and optimistic strategies for achieving concurrency control in mobile database systems are presented in literature. The pessimistic strategies achieve concurrency however they face the problem of blocking, whereas the optimistic strategies may not always keep the data consistent. The conflict resolution strategies may result in starvation of some of the mobile requests. This paper presents a hybrid concurrency control strategy by using the good properties of both pessimistic and optimistic approaches. The results specify that the proposed strategy performs better as compared to both pessimistic and optimistic strategies and reduces the starvation of transaction requests of various mobile devices.
