Description

Sensors nodes are small electronic devices which can gather environmental data, or can offer larger functional
 area, being able not only to measure the physical quantity, but also to modify, to store or to transmit it to a
base station or to other sensor nodes. We focus on this second type of sensors, also called intelligent sensors, 
connected through a wireless network. The network architecture is meant to assure larger deployments and
relevant information retrieval. Moreover, the lifetime of the system should be improved, by load balancing
computations, network latency needs to be diminished and security of data should be assured. Approaches are
similar to those used in traditional networks and in distributed applications. The major differences concern the
energy consumption, which is the critical point in sensor networks, and the low performances in terms of
communication, computation and storage for the sensor nodes.
These parameters modify considerably the algorithms proposed in classical wireless networks and in distributed
 systems.
The research group is interested more precisely in distributed storage, node self-organization and configuration,
concurrent medium access, routing and security. One phd thesis has been defended in 2008, two in 2009 and two
 others in 2010. A close collaboration is being developed with electronics engineers who design specific sensors.
Our solutions are applied to different applications, which are targeted to various domains: environmental
 monitoring (landslide monitoring, temperature measuring at Spitzberg), home automation, or industrial
process control and maintenance.
The team is made up of one professor, one associate professor and five phd students.
