The Contiki team is happy to announce that ContikiRPL has been made public! ContikiRPL is an open-source implementation of RPL – the proposed standard routing protocol for IPv6 in low-power and lossy networks. Read on for details on how to get ContikiRPL up and running.
RPL works by building and maintaining directed acyclic graphs toward root nodes. The protocol is the result of a collaboration between academia and industry in the ROLL working group at the IETF. In March 2010, an interoperability event hosted by the IPSO Alliance took place in Anaheim, CA. ContikiRPL participated in this event and was tested against a number of emerging RPL implementations.
