A mobile computing environment involves accessing information through a wireless network connection. The mobile unit may be stationary, in motion, and/or intermittently connected to a fixed (wired) network. We propose to superimpose a wireless-mobile computing environment on a multidatabase system to realize a system capable of effectively accessing a large amount of data over a wireless medium (MDAS - Mobile Data Access System). We show how one can easily map solutions from one environment to another. Furthermore, there are several issues involved in the ability to concurrently manage transactions. This paper proposes a new hierarchical concurrency control algorithm that address the limited bandwidth and frequent disconnections associated with wireless networks. The proposed concurrency control algorithm uses global locking tables created with semantic information contained within the hierarchy. The performance of the new algorithm is simulated and the results are presented.
