Failure Resilient Criteria for Mobile Web Services Transactions

This paper investigates into the transaction management of mobile web services, which is crucial to maintaining execution correctness of services and consistency of their underlying data. We propose a relaxed set of transaction correctness criteria, called Sacred (Semantic Atomicity, Consistency, Resiliency, Durability) and design protocols for enforcing these criteria in the execution of transactions. We evaluate the proposed criteria and present results in order to show that these criteria enhance the failure resilience of mobile web services transactions.
