Energy consumption in the sensor nodes of the Internet of Things (IoT)

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.
