Expanded use of computer simulation in business processes, particularly in financial planning and manufacturing, has resulted in the need to exchange data between simulation models and data resources on different locations. However this is hindered by several compatibility and security problems. Our goal was to develop and verify the performance of a lightweight, mobile agent based solution that would allow strong security, portability and access to heterogeneous data resources from a mobile platform.
