%X In a wireless data broadcast environment, there is a limited upstream bandwidth from mobile clients to the fixed database server. Traditional concurrency protocols are unsuitable in such an asymmetric communication environment. In this paper, we introduce a concurrency control protocol which integrates optimistic concurrency control and timestamp ordering. A mobile read-only transaction is weak consistent and the serialization graph consisting of all update transactions and a mobile read-only transaction is...
