Bugfix by Henrik Mäkitaavola: check that ICMP6 process is defined before invoking it

4f3e8d565c
Added a simple CSMA (Carrier Sense Multiple Access) mechanism that
...
works on top of an underlying duty cycling mechanism. The CSMA layer
retransmits packets that could not be sent because of a collision was
detected.
2010-01-25 11:46:44 +00:00
7ad93e5d18
Added a field to the struct mac interface:

channel_check_interval(). This function returns the interval by which
the duty cycling mechanism checks the radio channel for activity. It
is used by higher layer mechanisms to determine suitable timeouts for
retransmissions.

Bug fix for mysterious packet loss : check FIFO pin instead of FIFOP pin for any unread RX FIFO data;
...
Added protection of packet timestamp across interrupts. Note that race condition can still occur as interrupts and self-scheduled reads of the RX FIFO interleave in certain unusual patterns. More investigation is needed.

Use RTIMER_NOW() instead of rtimer_arch_now()
2009-12-09 18:08:26 +00:00
eff2203310
There were many bugs in the rtimer code, particularly one that made only one rtimer at a time work. We have a new rtimer system that we're testing, but in the meantime, I rewrote the rtimer code to explicitly support only one rtimer. Makes the code significantly simpler (and fixes a bug that was very hard to track down).

Significant improvements to the Contiki X-MAC:
...

* old unused code has been removed
* Contiki X-MAC now listens before sending a strobe to avoid MAC-level
collisions

consumption of receivers
* turn off radio for 1 ms between sending a strobe and expecting the
strobe ack

A simple addition with significant performance implications:
...
sicslowpan tags TCP packets with the PACKETBUF_ATTR_PACKET_TYPE_STREAM
flag, which makes the underlying power-saving MAC layer keep the radio
on for some time after transmitting the packet. This allows reply
packets to be processed directly, significantly increasing TCP latency
and throughput.

9d26bd663e
A new optimization to X-MAC: senders now keep track of when neighbors
...
last were known to be awake. When sending a packet, a sender does not
start to send strobes until the neighbor is expected to be awake. This
reduces power consumption for senders and decreases the contention in
the network as there are less packets in the air. Additionally, the
ACK optimization was improved so that data/ack exchanges now are
more efficient.

Refresh routes when a packet is received. Set a conservatively low route timeout (10 seconds).
2009-05-04 11:24:04 +00:00
c83c5c4c55
Removed automatic refresh of routes from the route_lookup() function and moved it into an explicit route_refresh() function. The previous behaviour was dangerous, since it meant that even bad routes that someone was looking for were considered fresh. Now such routes time out if they are not explictily refreshed (e.g., on a packet reception)

Rewrite of the collect module. The new version uses a packet queue for outgoing and forwarded packets so that more than one packet can be forwarded at the same time. The new version uses the packetqueue module to maintain the packet queue.

Added option to wait randomly before sending a packet. A few code cleanups. Avoid switching radio off when sending a packet with end-to-end acks, because an ACK may arrive shortly after the transmission.

Introduced two garbage collection mode: greedy and reluctant.
...
The greedy GC mode attempts to erase as many sectors as possible, and
it is therefore a slow operation, since the flash driver must wait
for about a second after erasing one sector. The former behavior was
to always do a greedy GC if file reservations fails due to lack of space.
The new reluctant GC stops after erasing one sector, and therefore
we often do not have to wait if there is no file system operation
in the time while the sector is being erased. We call the garbage collector
using this mode when removing a file that is not a micro log file, since
the remove function is called recursively for micro log files that are
erased because the corresponding ordinary file is erased.
This change increases the coffee test (examples/sky/test-coffee.c) speed
from 9 to 5 seconds.
