Workflows have been used successfully to model collaborative activities that have a well-defined structure. Workflow management systems today can execute workflows that range from a simple sequence of tasks to complex business processes, but have a common restriction in that they can only function in settings where the network is stable. This paper represents an initial investigation into the possibility...
CAST is a coordination model designed to support interactions among agents executing on hosts that make up a mobile ad hoc network (MANET). From an application programmer’s point of view, CAST makes it possible for operations to be executed at arbitrary locations in space, at prescribed times which may be in the future, and on remote hosts even when no end-to-end connected route exists between the...
The practice of using workflows to model complex activities in stable networks is commonplace and is supported by many commercially available workflow management systems (WfMSs). However, the use of workflows to model collaborative activities in mobile environments, while possible at the model level, has not gained traction due to the lack of a suitable WfMS for mobile networks and devices. This paper...
