1a13d25d33 Revised version of the X-MAC implementation that uses a ctimer instead 
of an rtimer for the periodic radio duty cycling. The benefit of this
implementation is that it leaves an rtimer free for user tasks. The
drawback is a slightly higher idle power consumption. This new version
is based on the current rtimer-based X-MAC.

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.

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.

822149f943 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

adamdunkels
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.

631af06c7c 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.

adamdunkels
4de1816e36 Added a new module called "framer" that creates MAC level frames to 
the packetbuf from packet attributes. Two framer modules are included,
one that creates 802.15.4 frame headers, and one that creates a
minimal "nullmac"-style header that only contains the link-local
addresses.

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.

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.

59145615b0 Changed packet forwarding from a runtime option to a compiletime option. This avoids pulling in uip-fw.o if forwarding isn't required (saves > 1400 bytes on 6502 targets). 
*** This change breaks all platforms calling tcpip_set_forwarding() ! These calls were intentionally not removed as they need to be replaced by setting the new compiletime option UIP_CONF_TCP_FORWARD - which should be done by the platform owners. ***

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.
