Bernard Tourancheau got a MSc. in Apply Maths from Grenoble University in 1986 and a MSc. in Renewable Energy Science and Technology from Loughborough University in 2007. He was awarded best Computer Science PhD by Institut National Polytechnique of Grenoble in 1989 for his work on Parallel Computing for Distributed Memory Architectures.

Working for the LIP laboratory, he was appointed assistant professor at Ecole Normale Supérieure de Lyon in 1989 before joining CNRS as a Senior Researcher. After initiating a CNRS-NSF collaboration, he worked two and half years on leave at the University of Tennessee on a senior researcher position with the US Center for Research in Parallel Computation at the ICL laboratory.

He then took a Professor position at University of Lyon in 1995 where he created a research laboratory and the INRIA EPI RESO, specialized in High Speed Networking and HPC Clusters. In 2001, he joined SUN Microsystems Laboratories for a 6 years sabbatical as a Principal Investigator in the DARPA HPCS project where he lead the backplane networking group.

Back in academia he oriented his research on sensor and actuator networks for building energy efficiency at LIP and CITI labs and associated INRIA EPI.

He was appointed Professor at University Joseph Fourier of Grenoble in 2012. Since then, he is developing research at the LIG laboratory Drakkar team about protocols and architectures for the Internet of Things and its applications to energy efficiency in buildings as well as multicores GPGPU’s algorithms optimization.

He has authored more than an hundred peer-reviewed publications and filed 10 patents.

The Internet of Things (IoT) is the new IT paradigm for the 2010’s decade. It promises a huge growth of the number of interconnected devices. Regarding the upcoming energy crisis this will only happen if the devices energy consumption is very low. Moreover, IoT devices are mostly supposed to be autonomous for years, using batteries or energy scavenging, which also bets for very low energy devices.

In this talk, we present several works that try to reduce as much as possible the energy consumption of the small devices’ communications while involved in the IoT. This includes research efforts from the hardware design to the system architecture and lots of software optimizations, especially in the networking stack. Our target IoT nodes are wireless nodes prototypes for environment sensing and main power communicating plugs.
