A context-adaptive workflow engine for humans, things and services

Abstract

We present PROtEUS--a context-adaptive workflow engine for smart environments. To cope with the heterogeneity and dynamic nature of ubiquitous systems, PROtEUS extends existing workflow engines by introducing dynamic sensor event streams, IoT services and humans as first class citizens. These resources can be selected at runtime based on their capabilities and context. We demonstrate PROtEUS in various Ambient Assisted Living scenarios involving complex compounds of sensors, actuators, humans and service robots.
