QoS, RF215 networking.

Itron is developing smart metering devices with 802.15.4 and PLC mesh networking. I’m involved in the
integration of a basic QoS solution and in Linux kernel bug fixing

- I worked on a Marshal Point protocol implementation, a security library, for zephyr and
Linux. The goal was to bring security on IOT devices.
- I worked on QMSI, a library for Quark based Microcontroller SoCs. I fixed and improved various drivers
(I2C, SPI, etc...), worked on QMSI bootloader and I also fixed serious bugs in Zephyr OS.

Itron is developing a new product, a water/gaz counter which send the metering value using radio. Using
an ARM4 board and an atmel radio. I am the main architect developer and I have implemented
- an embedded OS from scratch for specific Itron need
- a physical driver (read/write packet, turn on/off the radio, etc ...) (IEEE 802.15.4.g)
- a DHCP client
- a mac layer compatible with IEEE 802.15.4.e
- a port of contiki's UDP/IPv6 and RPL
- an application which read from UART the water counter value and send it to an another node
