Please note: The actual implementation of AODVv2 for RIOT has been moved here. After checking out the aodvv2-final branch, you can find the code at RIOT/sys/net/routing/aodvv2.
This implementation is work in progress. It is in no way complete. You can find a description of the subset of the AODVV2 Draft I implemented so far at docs/aodvv2_minimal.txt.

You can find a small demo application using aodvv2 in aodvv2/demo_application. To use it, run the following commands:

cd aodvv2/demo_application
../../riot/RIOT/cpu/native/tapsetup.sh create
make
sudo ./bin/native/demo_application.elf <tap device>

A small script to run tests on a desvirt grid can be found in the vnet_tester directory.

You can find more info about RIOT applications and how to run them at the RIOT OS Wiki.
