MOVIS: A system for visualizing distributed mobile object environments

This paper presents MOVIS—a system for visualizing mobile object frameworks. In such frameworks, the objects can migrate to remote hosts, along with their state and behavior, while the application is running. An innovative graph-based visualization is used to depict the physical and the logical connections in the distributed object network. Scalability is achieved by using a focus+contextfocus+context technique jointly with a user-steered clustering algorithm. In addition, an event synchronization model for mobile objects is presented. The system has been applied to visualizing several mobile object applications.
