dc7491f810
Bugfix and optimization: X-MAC did not properly switch the radio off after sending a packet, resulting in increased power consumption. For packets that require an ACK, we can let the radio be on in anticipation of the ACK (controlled with an WITH_ACK_OPTIMIZATION option)
2009-03-05 19:37:52 +00:00

Changed listen and transmit energy attributes so that they are named _TIME rather than _ENERGY, to indicate that they contain the time during which the radio was switched on and not the energy

Cleaned up old left-over code
2009-03-01 20:38:57 +00:00
7010eb84b8
Added support for communication power accounting. Energy is attributed to idle listening when the radio is switched off. Enegrgy is attributed to an incoming packet when it is received. Energy is attributed to an outgoing packet when it is transmitted.
2009-03-01 20:37:16 +00:00

4ec5167276
Rewrote the tcpip_output() and tcpip_set_outputfunc() so that the latter is a proper function (which simplifies debugging) and so that tcpip_output() checks if the output callback function is NULL before calling it
2009-02-20 21:21:56 +00:00
10deaa6fc6
Removed CLOCK_SECOND from stimers in uIPv6, stimers are already in seconds
2009-02-20 07:59:35 +00:00

2009-02-16 01:18:53 +00:00
aaa8c9d2c9
Construct the X-MAC header on the stack instead of directly in the packet header, because the packet header may be misaligned. A bit of cleanup in the code too.
2009-02-15 22:05:06 +00:00
e4b1ff461e
Added MAC-layer announcement beacons to X-MAC. Configuratble through XMAC_CONF_ANNOUNCEMENTS
2009-02-14 20:35:03 +00:00
585620c102
Reverted the recent change from random_rand() to rand(). It turned out that
...
since libc rand() returns a signed int, there were frequently problems with
timer values wrapping. By reverting to random_rand(), we can provide a
random generator that returns an unsigned and the timer problems are solved.
2009-02-11 11:08:53 +00:00
9d75781a78
Added packet attributes for energy spent on a packet (RIMEBUF_ATTR_LISTEN_ENERGY and RIMEBUF_ATTR_TRANSMIT_ENERGY)
2009-02-10 23:51:12 +00:00
b15198b9a8
Bugfix: the Chameleon header parser modules should not clear the packet attributes, because the MAC or radio layers may have added attributes already
2009-02-10 23:49:58 +00:00
e1ef13dad6
Reduced the size of the packet cache from four to two to avoid falseley dismissing fresh packets (the header field that hold sequence numbers is only two bits wide, hence all sequence numbers fits in a four-entry cache...)
2009-02-10 00:44:50 +00:00
6c95bd895a
Added default initialization of polite announcements. Not sure where the best place for this is, but this at least allow us to start experimenting with this.
2009-02-09 22:05:33 +00:00
3efb83c338
Added announcement includes
2009-02-09 21:09:42 +00:00

2009-02-09 21:08:12 +00:00
3670ef2f44
Rewrote the collect module so that it uses the announcement module rather than the neighbor-discovery module. This makes it possible to implement other annoumcement back-ends than the traditional broadcast-based neighbor discovery
2009-02-09 20:58:25 +00:00
dd9ffd87c4
Added missing #include announcement.h
2009-02-08 20:14:18 +00:00

Improved version of LPP with support for broadcasts as well as announcement data in the probes
2009-02-08 19:30:18 +00:00
91d280c4c9
Reverted to the old behaviour on broadcasts: send strobes for both unicast and broadcast packets.
2009-02-07 18:45:50 +00:00
4b71003c2f
Changed from random_rand() to rand() for better pseudo randomness
2009-02-07 18:43:45 +00:00
752291f450
Changed from random_rand() to rand() function for (pseudo) random numbers because random_rand() does not work that well
2009-02-07 16:16:31 +00:00
91e8487032
Added Doxygen documentation
2009-02-07 16:15:37 +00:00
be846d8c90
A new experimental network primitive called an 'announcement'. An
...
announcement is an (ID, value) tuple that is disseminated to local
area neighbors. An application or protocol can explicitly listen to
announcements from neighbors. When an announcement is heard, a
callback is invoked.
Announcements can be used for a variety of network mechanisms such as
neighbor discovery, node-level service discovery, or routing metric
dissemination.
Application programs and protocols register announcements with the
announcement module. An announcement back-end, implemented by the
system, takes care of sending out announcements over the radio, as
well as collecting announcements heard from neighbors.

bugfix: stopping timeout timer when we receive route reply (still limited to only one active discovery)

Bug fix by David Kopf - sicslowpan timeout was always set at 20 seconds, this greatly improves performance!!
2008-12-02 22:04:16 +00:00
50b1e60621
Rewrote the rimeaddr_copy() loop to use the ->u8 field instead of the ->u16 field (which now finally is removed)
2008-11-30 18:26:57 +00:00
6951d9d582
Removed the unused ->u16 field (it was there only as a convenience/laziness access method during the initial development of the Rime stack, but has caused problems when being there)
2008-11-30 18:26:06 +00:00

229d60d691
Neighbor ETX should accumulate over retransmission timeouts;
...
Best neighbor has minimum sum of routing metric and neighbor ETX. Previously best neighbor prioritizes routing metric before neighbor ETX, which often causes a poor neighbor with a good upstream path to be selected.
2008-11-12 10:47:17 +00:00

Inform user about (most likely unintentional) call of dummy_tcpip_output_function.
2008-11-10 21:00:53 +00:00
3b283a5ff3
Added dummy function so that tcpip_output() always is defined, even if tcpip_set_outputfunc() never has been called. This fixes a bug with programs attempting to use the network when compiled for the native platform.
2008-11-09 12:29:24 +00:00
5243d58ac5
Added logic for announcing that a network has a gateway to the outside world (with the function uip_over_mesh_make_announced_gateway()). The announced gateway sends a trickle message to the network, containing the address of the gateway. Other nodes will then know that packets destined to the outside world should go through the gateway node.

0c4f7bed8f
temporary fix to get sicslowpan.c working on the Sky platform:
...
conventional MAC implementations require a call to the MAC driver's
read function.
2008-11-06 20:45:06 +00:00
d73124cc5e
Bugfix: there was a problem with TCP segments not being properly retransmitted for protosockets-based applications. Cleaning up the logic around acknowledgements and retransmissions fixed the bugs pertaining to retransmissions of lost packets. This bugfix affects both the telnet server and the web server (which now work as expected wrt packet loss).

31509ad726
Fixed a bunch of bugs in the collection neighbor announcement/discovery code: neighbor announcments were not repeated unless there was a change in the ETX val. Neighbor announcements happened to often when there were changes in the ETX.
2008-08-15 19:00:38 +00:00
