Abstract : The integration of environment and information systems is progressing quickly since 10 years. This allows to monitor natural, physical or societal evolutions; to capture their logic and sometimes to control their effects. This integration is feasible thanks to many technical and scientific progresses: sensors, wireless communications, system on chips, batteries, distributed systems and geo-localization. The benefits are important for climate change monitoring and resource savings.In this context, we have firstly achieved a learning of technologies and several practical system realizations. We have produced a navigation software (QuickMap) allowing to interface gis databases and tile servers similar to OpenStreetMap, taking care of sensor locations and outputs. QuickMap is also a nice frontend to produce cellular systems oriented to physical simulations.Using the NetGen platform, we have produced a simulation framework allowing to schedule mobile moves with sensor field activities. A case study was leo satellites visiting remote sensor systems, with investigations on two algorithms suitable for data collection and control.Finally we have addressed the question of observation system virtualization by using an high level, process oriented virtual machine (tvm) to control the wireless link, a step forward to make the distributed and local behaviours homogeneous in terms of programming and simulation.Many of our developments are currently involved in active projects.This thesis was funded by a grant of Brest Metropole Oceane (BMO) and was achieved in a wireless research group at University of Brest, Lab-STICC laboratory.
