The integration of the Wireless Sensor Networks (WSNs) technology in the Internet world is one of the biggest challenges to enable the Internet of Things (IoT) vision. In order to really benefit of such kind of integration the IPv6 addressing method and communication protocols adopted in the IoT must be modified to match the WSNs scenario. This adaptation has been standardized with the name of IPv6 over Low power Wireless Personal Area Networks (6LoWPAN). In this paper the first adaptation of the SPEED geographic routing algorithm in a 6LoWPAN scenario is presented and its experimental validation in a real testbed is shown as compared with the AODVprotocol. Avoiding route creation time and showing reduced memory occupation, load balancing and flow shaping properties SPEED is an effective solution to support packet routing in 6LoW-PAN networks.
