The SSP-IQA-"Sustainable, Secure, and framework for Air Quality" project proposes to design, implement and validate a low-cost IT infrastructure with the necessary functionalities for collecting, transmitting, processing and analyzing data relating to outdoor and indoor air quality, particularly in public buildings such as schools/universities or hospitals. The infrastructure will make it possible to link up different platforms existing locally at the consortium partners, with the specification and implementation of efficient solutions at different levels (Fog and Cloud) and integrating security aspects at the level of data collection and transmission. The aim is to enable efficient, scalable handling of large volumes of data on air quality in general, and indoor air quality in particular. Estimating individual exposure inside buildings is a major challenge, due to the variability of temporal and spatial exposure, linked to individual behavior (e.g. studying in classrooms or eating in cafeterias), but also to the dynamics of the surrounding environment, which can also influence indoor air quality (e.g. meteorological conditions, nearby polluting factories, car traffic in the vicinity, occupational context). In this way, the specific environmental context of each consortium partner will enable rich and varied data to be collected, taking into account the multi-dimensional nature in time and space of the data needed in studies of air quality in internal and external environments. Information sharing (open data) is an important aspect of our project. In the medium and long term, the infrastructure can be used to share the data collected and enrich the data concerning air pollution. The creation of structured data, under controlled conditions (taking into account the context) and with real data, is one of the current gaps in the study of air pollution, particularly inside buildings. An important point is that this proposal also addresses international collaboration, in particular with Latin America (Mexico) and Africa (Cameroon), two countries for which the issue of air quality and its influence on human health is a priority area of research. Also, building on each partner's IoT platform the idea is to integrate our contributions and move towards a multi-platform vision for the constitution of a large volume of rich, structured data. Such an infrastructure will not just collect multi-dimensional data in time and space on the qualitý of the air, but also data on the state of computing, storage and transmission infrastructure resources and their energy costs. All to ensure intelligent operation covering sustainable development objectives specific to partners in Europe, America and Africa.
