be117afe04 After a lot of tweaking and twiddling with the timing of the ContikiMAC code and the mechanisms in the CC2420 driver, things seem to work somewhat stable now - knock on wood! 2010-04-04 07:49:30 +00:00

121ca946e1 Improved phase lock behaviour when neighbor is not duty cycling: senders notify receivers via the 802.15.4 pending bit that they are not duty cycling. Neighbors then will start sending packets immediately and not wait for neighbors' phase. Tweaking of ContikiMAC timers to make it more reliable. 2010-04-03 13:28:30 +00:00

7bab9316da Two major changes: 
* Low-power streaming. Experimental support for a low-power mode which
  allows rapid exchange of packets with a 16% duty cycle. Does not
  seem to function correctly yet though.

* Phase locking. When the phase of a neighbor has been detected, the
  sender assumes that the neighbor will keeps it phase and does not
  send more strobes than necessary to hit the receiver's channel
  check - even if the receiver does not acknowledge the reception of
  the strobes when it should have been awake. Instead, the sender
  stops strobing and tries again at a later time.

7165a3866f Significant rework of the Contiki data collection protocol: 
* the new version makes use of MAC-layer feedback so that bad paths
  can be identified quicker and then avoided.

* the new code uses transport layer ACKs that contain feedback from
  the collect protocol: when a packet cannot be forwarded due to lack
  of resources, the ACK contains a flag that indicates that the packet
  could not be forwarded. ACKs also contain the routing metric of the
  sender, which improves agility in face of rapid path changes.

* loop detection and management has been improved: with higher path
  metric agility, the system is more prone to short-lived routing
  loops. Instead of dropping looping packets, the new version adjusts
  the routing metric for the routes that exhibit loops so that the
  risk for future loops is reduced.

* make use of packet attributes to inform the MAC layer of how many
  times packets should be retransmitted.

ed52586e18 Rework of parts of the ContikiMAC code based on input from experimental results.

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.

f8c804e28b ntikiMAC: a new radio duty cycling mechanism that uses a combination 
of link-layer and MAC-layer mechanisms to achieve a very low power
consumption: during idle listening the radio is switched off between
99.2% and 99.6% of the time. One unicast transmission typically adds
between 0.07% and 1.2% additional radio time, depending on packet
size.

ContikiMAC uses the standard IEEE 802.15.4 message format and adds no
additional headers.

ContikiMAC is simple: it uses periodic two-shot channel sampling
during idle listening to keep the radio on-time down. Transmissions
are done with repeated transmissions until a link-layer ACK is
received.

fe30886b37 Added functionality for decaying routes: when a packet is sent over a route, it is decayed. If the route is not refreshed within four packets (with the route_refresh() function, which is called when a new packet arrives), the route is dropped. A route can be decayed at most once per second 2009-05-10 21:08:01 +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.

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),

5f3296e943 Changed packet drivers from services to plain processes. 
Now tcpip_output() is a function pointer that is supposed to be set via the macro tcpip_set_outputfunc(). Packet drivers do so on process startup.

Thus if there are several packet drivers in a Contiki system the one started last is the one actually used. This behaviour is especially useful for the 'IP forwarding' "meta" packet driver.

cada8d324f Up to now the DNS resolver relied on the uIP 1/2 second polling for its retry management (implementing a linear back-off). But Contiki 2.x uIP doesn't implement the 1/2 second polling for UDP connections anymore! Therefore I added an event timer to the DNS resolver for its retry management. I went for a 1 second interval (still with the same linear back-off) as compromise between officially recommended longer intervals (i.e. BIND with 5 seconds and exponential back-off) and a reasonable user experience for the self induced packet loss in ARP setups. 2007-01-07 13:52:25 +00:00

fb94d50410 Change typedef of uip_ipaddr_t from a vector type to a union. 
typedef union uip_ip4addr_t {
  u16_t u16[2];
  u8_t  u8[4];
} uip_ip4addr_t;

typedef uip_ip4addr_t uip_ipaddr_t;

This implies that one must consistently pass pointers to
uip_ipaddr_t:s and not mix and match pointers with
uip_ipaddr_t:s as was done earlier.
