adamdunkels	0db31db624	Moved declarations to the start of each function	2010-02-02 21:09:06 +00:00
adamdunkels	fcf60e9260	Removed the csma_init declaration in the mac_driver struct since it isn't needed and it breaks sdcc	2010-02-02 20:45:58 +00:00
adamdunkels	cc2be0f111	Remove compiler warnings	2010-02-02 16:33:07 +00:00
adamdunkels	88c661b0c2	Rewrote the netif time code so that is avoids the use of floating point numbers; some code style fixes	2010-02-02 16:32:03 +00:00
adamdunkels	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.	2010-01-31 18:44:23 +00:00

adamdunkels	0b58ca3b22	Bugfix: split full size TCP segments if they match the MSS definition, not only the buffer size definition	2010-01-25 13:53:15 +00:00
adamdunkels	7615a6cf47	Bugfix by Henrik Mäkitaavola: check that ICMP6 process is defined before invoking it	2010-01-25 13:37:05 +00:00
adamdunkels	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.	2010-01-25 11:46:44 +00:00
adamdunkels	7ad93e5d18	Added a field to the struct mac interface: ... channel_check_interval().

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.	2009-11-02 11:58:56 +00:00
adamdunkels	c7a91ad4a2	Bugfix: UIP_TCP_BUF -> BUF	2009-10-27 23:09:58 +00:00
adamdunkels	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.	2009-10-27 22:34:08 +00:00

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.	2009-10-19 18:30:03 +00:00
nifi	ae226c5917	* Set sender and receiver packet attributes on incoming packets ... * Added link layer destination check	2009-10-19 11:25:54 +00:00

adamdunkels	fb037e0afb	Added function for sending an UDP packet to a specified IP address and port number over an existing UDP connection	2009-10-18 22:02:01 +00:00
adamdunkels	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.	2009-10-18 13:19:25 +00:00
nvt-se	31f41d842e	* decline route discovery requests if we have one in the air ... * and, by popular demand, switched PRINTF to printf in the debug macro. :-)	2009-10-08 16:30:26 +00:00

nvt-se	83f2b9ae57	include ctimer.h, since ctimer's are used in the neighbor_discovery_conn struct.	2009-05-30 19:40:39 +00:00
nvt-se	9277f922f1	fixed some documentation typos. ... also uc -> unicast, stuc -> stunicast.	2009-05-26 13:58:53 +00:00

adamdunkels	fe5a1f1068	Added an optimization option that avoids multiple simultaneous broadcasts from neighbors: when a broadcast is to be sent, a sender does not send until it knows that no other nodes are broadcasting.	2009-05-10 21:09:05 +00:00
adamdunkels	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
adamdunkels	6bf8e0b478	Bugfix by Takahide Matsutsuka: too few items in array, which caused problems with sdcc	2009-05-08 08:52:55 +00:00
zhitao	48d4800f08	removed reference to undefined function in mspgcc	2009-05-06 15:34:28 +00:00

zhitao	58940ecbf8	minor documentation fixes	2009-05-06 08:37:48 +00:00
adamdunkels	1752b53f74	Refresh routes when a packet is received. Set a conservatively low route timeout (10 seconds).	2009-05-04 11:24:04 +00:00
adamdunkels	c83c5c4c55	Removed automatic refresh of routes from the route_lookup() function and moved it into an explicit route_refresh() function. The previous behaviour was dangerous, since it meant that even bad routes that someone was looking for were considered fresh. Now such routes time out if they are not explictily refreshed (e.g., on a packet reception)	2009-05-04 11:23:30 +00:00
adamdunkels	f5a57a4e54	Fixes by Ward Van Heddeghem (reapplied from versioin 1.24)	2009-04-30 20:21:06 +00:00
adamdunkels	e70cf0c7c6	Rewrite of the collect module. The new version uses a packet queue for outgoing and forwarded packets so that more than one packet can be forwarded at the same time. The new version uses the packetqueue module to maintain the packet queue.	2009-04-29 20:48:57 +00:00
adamdunkels	c489b1118d	New module: packetqueue. The packetqueue module maintains packet queues for other modules.	2009-04-29 20:47:30 +00:00

adamdunkels	c02a82ac41	Tag outgoing TCP packets with the ERELIABLE attribute so that an underlying power-saving MAC protocol can treat them differently, because it knows that an ACK might be arriving soon	2009-04-29 11:40:33 +00:00
adamdunkels	c9df0ab123	Bugfix in debug message printout	2009-04-28 14:01:46 +00:00
adamdunkels	81ef83b856	Added option to wait randomly before sending a packet. A few code cleanups. Avoid switching radio off when sending a packet with end-to-end acks, because an ACK may arrive shortly after the transmission.	2009-04-28 14:00:53 +00:00
adamdunkels	fdd05f5c71	Bugfix: psock send should use PT_WAIT_UNTIL() not PT_YIELD_UNTIL(). This improves TCP throughput by 100x under minimal-net	2009-04-28 13:52:04 +00:00

adamdunkels	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.	2009-02-05 19:32:01 +00:00

adamdunkels	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.	2008-11-09 12:20:56 +00:00

oliverschmidt	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. ***	2008-03-29 15:19:25 +00:00

adamdunkels	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: Adam Dunkels, Fredrik Osterlind, Zhitao He. An Adaptive Communication Architecture for Wireless Sensor Networks. In Proceedings of the Fifth ACM Conference on Networked Embedded Sensor Systems (SenSys 2007), Sydney, Australia, November 2007. http://www.sics.se/~adam/dunkels07adaptive.pdf This is a rewrite of the code that was developed for the paper.	2008-02-25 02:14:34 +00:00

oliverschmidt	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
