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.

Significant improvements to the Contiki X-MAC:
...
* the code is simplified, particularly the duty cycling logic
* old unused code has been removed
* Contiki X-MAC now listens before sending a strobe to avoid MAC-level
collisions
* broadcasts are sent directly, without strobes, reducing the power
consumption of receivers
* turn off radio for 1 ms between sending a strobe and expecting the
strobe ack

chameleon returns 1 only on successful rime_output()
2009-11-13 09:14:52 +00:00
583dd11c55
rime_output() now returns RIME_OK or RIME_ERR depending on the MAC return value.
...
this patch may affect Rime sniffers running on top of MAC protocols that do not yet return generic MAC return values
2009-11-13 09:10:24 +00:00

Enable stream mode by default, remove LED debug mode
2009-11-04 16:02:45 +00:00
5aab2eb77d
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.

Bugfix: Active TCP connections in uIP are made by first setting up the
...
TCP connection state, then poll uIP to send out the first SYN. Until
now, however, the SYN was not sent as part of the poll, but at the
first retransmission. This is now fixed.
