As discussed in #2725, this commit renames a number of stacksize constants to
better convey their intended usage. In addition, constants for thread priority
are given a `THREAD_` prefix. Changes are:
* KERNEL_CONF_STACKSIZE_PRINTF renamed to THREAD_EXTRA_STACKSIZE_PRINTF
* KERNEL_CONF_STACKSIZE_DEFAULT renamed to THREAD_STACKSIZE_DEFAULT
* KERNEL_CONF_STACKSIZE_IDLE renamed to THREAD_STACKSIZE_IDLE
* KERNEL_CONF_STACKSIZE_MAIN renamed to THREAD_STACKSIZE_MAIN
* Move thread stacksizes from kernel.h to thread.h, since the prefix changed
* PRIORITY_MIN renamed to THREAD_PRIORITY_MIN
* PRIORITY_IDLE renamed to THREAD_PRIORITY_IDLE
* PRIORITY_MAIN renamed to THREAD_PRIORITY_MAIN
* Move thread priorities from kernel.h to thread.h since the prefix has changed
* MINIMUM_STACK_SIZE renamed to THREAD_STACKSIZE_MINIMUM for consistency
``debug.h`` was included before ``ENABLE_DEBUG`` was set to 0 or 1. In consequence, setting ``ENABLE_DEBUG`` to 1 had no effect. This should be fixed now.
For some reason the call to aodv_packet_reader_handle_packet() got lumped in with the check if a received packet is ours. In consequence, all packets which were not sent by the node that received them (i.e. the important ones) were silently ignored, preventing any routes from being established.
This should be fixed now: foreign packets are now handled again, while own packets are ignored.
Also, I made the corresponding comment a bit less passive-aggressive.
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.
