Creating mobile ad hoc workflows with Twitter.

The wide-spread adoption of powerful mobile devices allows for the design of workflows while on the move. In this paper, we leverage established SOA principles towards mobility in design and execution. For this purpose, we introduce a lightweight Service workflow model that is tailored for the needs of ad-hoc creation and mobility. We show how sensor data from mobile devices can be included during the design of Service workflows and we address crowd sourcing aspects for the deployment and execution of Service workflows. We present a proof of concept prototype application that supports the creation of Service workflows on mobile devices.
