N2 - Conventional concurrency control protocols are inapplicable in mobile computing environments due to a number of constraints of wireless communications. In this paper, we design a protocol for processing mobile transactions. The protocol fits the environments such that no synchronization is necessary among the mobile clients. Data conflicts can be detected between transactions at the server and mobile transactions by a two-stage validation mechanism. In addition to relieving the server from excessive validation workload, no to-be-restarted mobile transactions will be submitted to the server for final validation. Such early data conflict detection can save processing and communication resources. Moreover, the protocol allows more schedules of transaction executions such that unnecessary transaction aborts can be avoided. These desirable features help mobile transactions to meet their deadlines by removing any avoidable delays due to the asymmetric property. © 2000 Springer-Verlag Berlin Heidelberg.
