e34eb54960 A work-in-progress rework of the Contiki MAC and radio layers. The 
main ideas are:

* Separates the Contiki low-layer network stack into four layers:
  network (e.g. sicslowpan / rime), Medium Access Control MAC
  (e.g. CSMA), Radio Duty Cycling RDC (e.g. ContikiMAC, X-MAC), and
  radio (e.g. cc2420).
* Introduces a new way to configure the network stack. Four #defines
  that specify what mechanism/protocol/driver to use at the four
  layers: NETSTACK_CONF_NETWORK, NETSTACK_CONF_MAC, NETSTACK_CONF_RDC,
  NETSTACK_CONF_RADIO.
* Adds a callback mechanism to inform the MAC and network layers about
  the fate of a transmitted packet: if the packet was not possible to
  transmit, the cause of the failure is reported, and if the packets
  was successfully transmitted, the number of tries before it was
  finally transmitted is reported.
* NULL-protocols at both the MAC and RDC layers: nullmac and nullrdc,
  which can be used when MAC and RDC functionality is not needed.
* Extends the radio API with three new functions that enable more
  efficient radio duty cycling protocols: channel check, pending
  packet, and receiving packet.
* New initialization mechanism, which takes advantage of the NETSTACK
  #defines.

f9e991c0dd Turning of the MAC protocol in the IPv4-over-mesh actually made performance worse due to broadcasts being received multiple times, which interfered with SLIP I/O 2010-02-03 01:20:47 +00:00

88fb1c80c9 Do not activate the sensors by default: sensors should be activated by the applications that need them 2010-02-02 16:25:30 +00:00

d0d52638b8 Disable (debugging-) initialiation of aaaa:: address; add CSMA MAC for IPv6/6lowpan 2010-02-01 11:55:04 +00:00

5922402b3e Added the CSMA MAC mechanism on top of the default duty cycling 
mechanism X-MAC. The CSMA is configurable with a MAC_CSMA define, just
like the MAC protocol is configurable with the MAC_DRIVER define.

0076bfe8a5 Changed the name of the 'serial' module to 'serial-line' to signify that the module is about lines of data from the serial port, not individual bytes, and to make sdcc happy 2009-03-17 15:56:32 +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.

8e5d255b5b Moved initialization of the SHT11 until after other initialization: this seems to fix a bug where the SHT11 temperature and humidity values started varying wildly. 2008-07-08 08:23:24 +00:00

c38d43c387 Change order of initialization so that Rime is initialized before uIP-over-Rime. Send out a new gateway command if a spurious (erroneous) gateway command is received. (Note for the future: this will cause a ping-pong problem with two correct gateways in the network; need to come up with a better solution for this.) 2008-03-03 20:23:53 +00:00

02ee418313 Moving timesynch.[ch] from sys/ to core/net/rime as they have more to do with Rime than with the kernel 2008-01-14 14:22:16 +00:00

f935be10c9 Added initalization of the serial library. Changed LPM3 to LPM2 since the current serial driver does not work with LPM3 yet (we need to add start edge detection interrupt support to fix that). 2008-01-08 08:21:03 +00:00

381f5dc4cc Initialize Rime address from hardware MAC address if no node ID has been configured. Be more explicit on how Rime address is assigned from node ID. Set time synch authority level from Rime address rather than node ID. Fix bug that put CPU in LPM2 instead of LPM3. 2007-12-17 12:35:23 +00:00
