Abstract
Workflows provide flexible and natural ways in the coordination of human and machine activities. Distinct from the past work, this research aims at the design and implementation of an open-source workflow engine for embedded systems, especially those for Sensor Information Systems for Active Retirees and Assisted Living (SISARL) devices. A subset of the XML Process Definition Language is identified and proposed for SISARL applications. With the considerations of the restrictive resource support of embedded systems and the needs of SISARL devices, a workflow engine is designed and
implemented in C. Implementation issues on system configuration and workflow implementations are then presented. The capability and the overheads of the workflow engine are evaluated by a case study over a medication dispenser.
