Distributed Coordination of Workflows over Web Services and Their Handheld-Based Execution

The current state of the art of workflow composition over web services employ a centralized composite process to coordinate the constituent web services. Therefore, the coordinator process is complex, less scalable, and bulky. This paper introduces an architecture and associated techniques for distributed coordination of these workflows, and a prototype system, namely BondFlow system, with capability to control workflow execution using a handheld device. We distribute the centralized coordination logic of traditional workflows by (i) extending the stateless web services into self-coordinating entities using coordinator proxy objects, and (ii) creating the workflow over these entities by interconnecting them into a distributed network of objects using web bond primitives. Previously, we have developed web bond primitives to enforce interdependencies among autonomous entities. The prototypedr BondFlow systeh provides a platform to configure such distributed workflows, producing coordination components with a footprint small enough to be executed on a handheld (footprint no larger than 150 KB).
