Bottlenecks of S4M
The generic architecture is characterized by multiple information inputs, communicating "wireless" among themselves, collected on a central computer with pre-diagnosis and alert missions. If the principles are classical and general, the technological development can be very different depending on the application: autonomy of sensors, transmission procedures, diagnostic algorithms, topological characteristics ranging from the integrated matrix (in the case of bio-chips for example) to Global climate monitoring (climate disaster forecasts for example).
Scientific locks for monitoring based on distributed instrumentation have been clearly identified:
- Nodes must be autonomous: in data processing, decision making, communication between them and with the central "server" but also in energy management;
- Nodes must be able to reconfigure themselves independently or via a wireless connection: variable architecture, versatile, microfluidic network;
- Nodes must be mobile and non-invasive: geolocation, wireless communication with very low energy consumption, biocompatibility.
- Distributed nodes must be able to provide reliable, high-level monitoring: data collection and aggregation, multisensory analysis, signal processing, behavioral analysis of the functioning of the "system" to be monitored, taking into account the context and the direct or indirect environment ...
