Formalizing Mobile Cloud Service Migration with Event-B

Service migration is a key feature for mobile cloud, which should run correctly before and after the migration. This paper presents our experiences on modeling and verifying service migration with Event-B. We start from the initial Event-B model and conduct model refinement process to complete the service transfer model. Using the capabilities of Event-B, we verified the correctness and reliability of the model. We evaluate our work with a mobile cloud service transfer application and simulate to services transfer process, which shows the effectiveness of our work.
