and in terms of a number of metrics. While detailed utility functions and algo-
rithms are discussed, this paper focuses on a proof-of-concept prototype imple-
mentation of a practical solution for quality-driven data acquisition from mobile
sensors by means of the QoS Manager component built around a cloud-based
publish/subscribe middleware. It has shown to be applicable in particular for
mobile IoT application scenarios.
7 Conclusion
The paper presents the OpenIoT solution for integrating mobile sensors and
managing data acquisition from such sensors in a quality-driven fashion. It pro-
vides an integrated view on the OpenIoT components providing support for
mobile IoT environments, namely the CUPUS middleware and QoS Manager
component. The design of a stand-alone QoS Manager component interfacing
with the OpenIoT CUPUS middleware is presented. The QoS Manager enables
improved energy-eciency for mobile sensors while satisfying global application
requirements for both sensing coverage and energy monitoring and management.
Further on, details on the integration of the QoS Manager with the CUPUS mid-
dleware and the rest of the OpenIoT platform are provided to describe how the
proposed solution can be used for optimized mobile sensing while taking into
account sensor accuracy, energy-eciency, and data redundancy. The paper fur-
ther presents the prototype implementation and deployment of the QoS Manager
interacting with CUPUS in the context of an Urban Crowdsensing case study
focused on opportunistic sensing of air quality via mobile sensors and devices.
Future steps will focus on experimental testing of the proposed architecture
in the scope of a real air quality monitoring field study.
