In this paper we analyze periodic maintenance strategies for managing replicated objectsin mobile wireless environments. Under periodical maintenancestrategies, the system periodically checks local cells to determineif a replicated object should be allocated or deallocated in a cell to reduce the access cost.We develop a performance model based on Petri netsthat considers the missing-read cost, write-propagationcost and the periodic maintenance cost with the objective to identify optimal periodic maintenance intervals to minimize theoverall cost. The analysis results show that the overall cost is highwhen the user arrival-departure ratio andthe read-write ratio work against each other and is low otherwise. In all cases, there exists an optimal periodic maintenance interval that would yield the minimum cost.Further, the optimal periodic maintenance interval increases as the arrival-departure ratio andthe read-write ratio work in harmony.
