40583fe112 Removed the polite announcement code, since it was not used, and enabled the broadcast announcement code by default. Increased the default intervals for broadcast announcements. 2010-10-03 20:10:22 +00:00

f6e0b46f38 * Made Chameleon header processing module configurable (CHAMELEON_CONF_MODULE)
* Removed the unused init function from header processing modules
* Added option CHAMELEON_CONF_WITH_MAC_LINK_ADDRESSES to specify that
  MAC link addresses should be used instead of Chameleon's own encoding
  of sender and receiver. This avoids encoding the link addresses twice
  when the MAC RDC has its own addresses.

c20047f657 Changed the network stack to use different structures for the different layers (network_driver, mac_driver, rdc_driver, radio_driver). This helps to avoid incorrect configuration. 2010-02-23 20:09:11 +00:00

b746b7fc06 Reworked the Rime/Chameleon interface so that packets now always hit Rime before Chameleon. Chameleon is now only called by Rime. This makes packet sniffing easier, and allows for sniffing packets after their header has been processed by Chameleon, thereby making per-packet power profiling much easier to implement 2010-02-23 18:29:53 +00:00

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.

d7b7b05d0e Moved the neigbor_init() call to the collect module, since it is the only one that currently uses it 2010-02-03 20:38:33 +00:00

71ffde578e Moved route_init() into mesh instead of the generic rime initialiation 2010-01-25 13:54:26 +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

65eb5fd4e8 Renamed the rimebuf module to packetbuf to signal that the module is used outside of a pure Rime context (e.g., the sicslowpan code uses it). 2009-03-12 21:58:20 +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

412facb831 This is an initial commit of an implementation of the Chameleon
architecture for the Rime stack for Contiki. The Chameleon
architecture separates the header processing from the Rime protocol
logic. Instead of having each protocol create its own part of the
packet header, protocols use packet attributes. Before sending a
packet, a special Chameleon header processing module creates a packet
header from the packet attributes. The same Chameleon module parses
incoming packets and creates packet attributes from the header.

The details are in our SenSys 2007 paper:

Architecture for Wireless Sensor Networks. In Proceedings of the Fifth
ACM Conference on Networked Embedded Sensor Systems (SenSys 2007),
Sydney, Australia, November 2007.

This is a rewrite of the code that was developed for the paper.

042180c13f Rewrote the sniffer code to use a list, which makes it possible to add any number of sniffers. Sniffers now can be both for incoming and outoing packets. 2008-01-14 09:42:00 +00:00
adamdunkels
88a010acdc Added a simple sniffer callback, which currently is a hack - a better solution would be a list of sniffers for both outgoing and incoming packets, but this will do for now. 2008-01-08 07:53:02 +00:00
