Benoît Thébaudeau 4deba89f81 rdc: duplicate packets: Keep only the last sequence number for each address
According to IEEE 802.15.4e (§6.4.3.9), in order to detect duplicate received
MAC-layer frames, only the most recently received frame's sequence number needs
to be stored for each unique device address. Doing so limits the possible false
duplicate packet detections to a single sequence number. This also allows to
keep the last sequence number of more device addresses for the same value of
MAX_SEQNOS.

Benoît Thébaudeau 477a4a7178 rdc: duplicate packets: Factor out detection code
The code detecting duplicate packets in the RDC layer had been copied into most
RDC implementations. Factor it out into a new mac-sequence module in order to
have a single instance of this code.

Benoît Thébaudeau 14db3382af csma: Initialize sequence number with random value
According to IEEE 802.15.4 (§5.1.6.1, §6.4.2), the MAC sequence numbers should
be initialized to random values. This was already the case in
framer-802154.c:create(), but not in csma.c:send_packet(), sometimes causing
false detections of duplicate MAC-layer packets in other devices when a device
was restarted too quickly. This patch decreases the probability of such an
event.

Adam Dunkels faff1c2a7e Preliminary support for RPL node types. This change allows a node to be in any of three given types:
* Mesh: this is the normal case. Nodes route data on behalf of others and the node can be reached via a DAO route.
* Leaf: the node does not route data on behalf of others, but others can route data to the node (it has a RPL DAO route).
* Feather: this is a new type of node. A feather node routes data on behalf of others, but does not install DAO routes in the network. Feather nodes allow having a larger number of nodes than the RPL network can sustain in terms of routing tables.

This commit introduces the RPL node types and the feather mode, but does not add support for the leaf node type.

Adam Dunkels 61ea7fbb1c RPL DAO timers and management:
* Added a DAO lifetime timer that sends out a new DAO after half the lifetime of the DAO. This allows implementing DAO route soft state that avoids routing tables in the network keeping stale routes for ever.
* Added ways to schedule a new DAO transmission as well as cancelling an active DAO transmit timer, which makes it possible to do nodes that don't send DAOs.

Adam Dunkels b31e84649a If the 6lowpan layer is currently reassembling a packet, and a non-fragmented packet comes along, this is a sign that one of the fragments were lost (as they normally would arrive back-to-back, in sequence).

Adam Dunkels 0aa448f190 6lowpan fragmentation bugfix: the 6lowpan code had an unfortunate
interaction with the behavior of the rdc layer. If the first packet of a
fragment transmission was lost, the remaining packets would get dropped
on reception. Moreover, the reception code contained a bug that
sometimes would cause fragments to be misidentified as fragments. Taken
together, these problems would result in a pathelogical network
breakdown if too many fragmented packets would occur simultaneously.

George Oikonomou 62366813b0 Provide a macro to read rimestats when enabled 2013-03-20 21:14:34 +00:00
George Oikonomou 12860ce5d4 Fix #183 (short term fix)
This is a temporary fix for #183, so that things can
build cleanly until the issue is fixed properly.

If RIMESTATS_CONF_ENABLED is 0, rimestats.foo will always
read as 0, since RIMESTATS_ADD(foo) doesn't do anything

Adam Dunkels 7742b05d8c Major bugfix: when nullrdc is asked to send a list of packets, send the list of packets and not just the first packet - this is essential for retransmissions of fragmented IP packets to work 2013-03-18 13:35:29 +01:00

Adam Dunkels 3efa84ecc8 New mechanism for computing the 6lowpan header length dynamically, depending on how large header the framer creates. Also check the incoming packet for buffer overflow. 2013-03-18 11:19:22 +01:00

Adam Dunkels 5993595a8f A number of updates to nullrdc
* add a few rimestats to keep track of sent and received acks
* made a number of configuration options possible to override (ack timing)
* added the logic for sending 802.15.4 link layer ack packets, despite not being able to guarentee the 802.15.4 MAC timing
* increased the number of sequence numbers to keep track of for duplicate filtering

Adam Dunkels 2d50a40643 A default configuraion file for Contiki
The contiki-default-conf.h file is intended as a safe fallback for
a number of configuration options in Contiki, to avoid putting too
much in the individual contiki-conf.h files.
