The inherent limitations of mobile environments like disconnections, mobility, bandwidth etc affects the performance of system when several mobile clients access the shared data items at the same time. Several timeout based strategies are implemented in literature to deal with the starvation of data items during disconnections and mobility. This increases the abort and rollback rates. In the proposed heuristic approach, the time for execution of a transaction can be predicted based on the given timer value for a specific mobile client. The simulation results show the time for execution can be dynamically estimated given the timer value and vice versa for a particular request originating from specific mobile clients. This increases the throughput of the system as compared to the timer based strategies proposed in the literature.
