These headers do not provide full stl functionality,
but a small subset:
* thread and this_thread
* condition_variable (some timed functions are missing)
* mutex, lock_guard and unique_lock
The motivation behind this module is to allow for address handling
functions where they, but not the full IPv6 functionality might be
needed. This new version of the IPv6 address data type utilizes the
byteorder.h header to enforce network byte-order on its members.
This PR proposes an approach to reduce the thread count of RPL.
The current RPL/Trickle stack needs about 5 threads to handle tasks
like updating the trickle timer, routing entries and the transmission of
DAOs.
This PR modifies RPL to use only one thread with a looped `msg_recv()` call.
The message is then multiplexed to the right task.
This PR depends on #1766.
It contains a minimal implementation of the AODVv2 routing protocol.
*Not* implemented are:
- AckReqs
- alternate metrics
- multiple interfaces
- clients and Client Networks
- buffering
- all addresses, TLVs, and features that are marked as optional
An example application can be found at https://github.com/Lotterleben/RIOT-AODVv2/tree/master/aodvv2_demo.
The implementation relies heavily on a functioning Neighbor Discovery Protocol.
It might be necessary to fill the neighbor cache manually with the current state
of RIOTs NDP implementation.
The value of AODVV2_MAX_UNREACHABLE_NODES has been chosen arbitrarily and will be subject to
future improvement.
Please note that based on my experience, with the default transceiver
buffer size (3) of the native port, about 2/3 of the route discoveries
will fail. This has been addressed in issue #1747. It is advised to increase
the transceiver buffer size when using AODVv2 as a routing protocol.
