WHAM: supporting mobile workforce and applications in workflow environments

Abstract

We have prototyped a system called WHAM (Workflow enHAncements for Mobility) to support a mobile workforce and applications in workflow environments. The goal of WHAM is to effectively handle the constraints of network connectivity and the mobility of workflow resources for workflow applications. In this paper, we describe the design and architecture of WHAM. We also describe the mobile resource management approach introduced in WHAM to support the adaptability and scalability of resource management for location-dependent activities.
