I am currently working on two research projects:
I was also affiliated with the (now concluded) ForToo project, an ISEC 2010 action grant on the development of advanced forensic tools against Internet abuse, with focus on forensic analysis of android devices and wireless sensors.
Over the past few years I have also been working on large-scale, IPv6-enabled Wireless Sensor Networks and the Internet of Things. I have been conducting research and development on real sensor deployments, focusing on aspects such as multicasting; congestion control, routing, over-air programming and code dissemination. For this work I have been using the Contiki embedded Operating System.
I am one of the main developers / maintainers of the Contiki OS. I have contributed the code which adds support for IPv6 / 6LoWPAN multicast and I am maintaining Contiki's port for the Texas Instruments CC2538 and CC13xx/CC26xx Cortex M3-based SoCs. I have also contributed (and am currently maintaining) two older hardware ports: i) for Texas Instruments' SmartRF 05 Evaluation Board with cc2530 EMs and ii) for Sensinode devices (TI CC2430-based USB NanoRouters (N601) and NanoSensors (N740)). For more information about my work on those two Contiki ports, please see the wiki on GitHub.
