Networked Smart Objects: Moving Data Processing Closer to the Source

The satisfaction of security and data quality requirements plays a fundamental role in the Internet of Things (IoT) scenario. Such a dynamic environment requires the adoption of heterogeneous technologies to provide customized services in various application domains and both security threats and data quality issues need to be addresses in order to guarantee an effective and efficient data management. In this paper, a lightweight and cross-domain prototype of distributed architecture for IoT is presented and evaluated by means of open data provided by different sources. We show how users can access different types of data by changing security and quality requirements.
