Towards a (de)composable workflow architecture to define data collection policies

Overview & Synopsis

Sensor networks are classically used in the Internet of Things to collect data, typically supporting Smart Cities or Smart Homes use cases. However, a deep knowledge of these networks is needed to properly develop applications over the deployed systems. This leads to a target mismatch: developers know how to exploit the collected data to develop large-scale " smart " systems, but do not have enough knowledge to technically enact and compose such behaviors on a given sensor network. In this paper, we envision a tooled approach that supports data collection policies management at a higher level of abstraction, fostering reuse. We discuss an architectural abstraction based on workflow concepts assisting developers in expressing data collection policies. The resulting architectures are then composable to be enacted on the same sensor network, but they can also be partially reused through a selection operator.
