The Pessimistic commit protocol specifies set of rules which guarantee that every single transaction in a mobile database environment is executed to its completion or none of its operations are performed. To show the effectiveness of pessimistic commit protocols, a generic simulator is designed and implemented to demonstrate how the transactions are committed and how the data consistency is maintained when the transactions are executed concurrently. Further the constraints imposed by mobile database environments like mobility, blocking of data items etc. are effectively handled. The simulator is tested for efficiency for all timeout based strategies proposed in the literature.
