i am trying to propose a modification to RPL, but at this time i need to send a message to neighbor nodes directly, without routing through the root (non-storing mode) or through a common parent (storing mode).
I need a quick alternative other than modify the RPL itself (unfortunately i don't have the time nor the knowledge to do it fast enough). I basically need to add an alternative routing scheme in RPL for some circumstances.
I thought about manually building a message and using the csma mac layer directly to send it using the lladdr (or using a modified "output(...)" function in sicslowpan.c), but i also need to be able to capture it in the next node to "route" it manually.
I just found out about link local addresses (ie.: fe80:...), can this be used instead? The messages will not be routed using the DODAG?
Can anyone point me to the right direction? Thank you in advance!
