Abstract

Mobile agents are ideal for mobile computing environments because of their ability to support asynchronous communication and disconnected data processing. In this paper, we present a prototype set of extensible mobile-agent based services that allow the definition, materialization, maintenance and sharing of views created over remote web-accessible datasources, called ViSMA (Views Supported by Mobile Agents). ViSMA's primary goal is to support the customization and personalization of views by mobile users carrying lightweight devices of various connectivity and resources such as portable computers and PDAs. It achieves efficient view customization by localizing the materialization of view fragments of a complex view within different mobile agents which monitor each other's movement in order to minimize communication costs. ViSMA has been fully implemented over a mobile agent platform and tested using three alternative mobile client types.
