In an environment with support for mobile computing, we may have a collection of
autonomous, distributed, heterogeneous and mobile databases, denoted Mobile Database …

This paper presents a cooperative transaction model for shared engineering databases
which provides a higher degree of concurrency and process parallelism in CAD. As …

In this work, we present a new approach to control concurrency in multidatabase systems.
The proposed approach is based on the use of semantic knowledge to relax the notion of …

Abstract We define a Mobile Database Community (MDBC) as a dynamic collection of
autonomous mobile databases in which each database user can access databases in the …

The topology of a mobile ad hoc network (MANET) may change randomly and rapidly at an
unpredictable time, since nodes are free to move arbitrarily. In such an environment, we may …

A wireless broadcast environment is defined as a mobile computing environment in which
data are delivered to mobile clients by means of a broadcast-based mechanism. Of course …

A multidatabase consists of a collection of autonomous local databases. Systems used to
manage multidatabases are called multidatabase systems MDBSs. In such a system, global …

In a database system, the scheduler has the goal of synchronizing operations belonging to
several concurrent transactions. The scheduler implements a concurrency control protocol …
