zhitao 229d60d691 Neighbor ETX should accumulate over retransmission timeouts;
Best neighbor has minimum sum of routing metric and neighbor ETX. Previously best neighbor prioritizes routing metric before neighbor ETX, which often causes a poor neighbor with a good upstream path to be selected.

oliverschmidt 75ffd0640c Inform user about (most likely unintentional) call of dummy_tcpip_output_function. 2008-11-10 21:00:53 +00:00
adamdunkels 3b283a5ff3 Added dummy function so that tcpip_output() always is defined, even if tcpip_set_outputfunc() never has been called. This fixes a bug with programs attempting to use the network when compiled for the native platform. 2008-11-09 12:29:24 +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
adamdunkels 8851a6359a Remove unguarded printf() 2008-11-09 12:16:05 +00:00
oliverschmidt 28889f2210 Commented out otherwise unguarded printf(). 2008-11-06 23:15:58 +00:00
nvt-se 0c4f7bed8f temporary fix to get sicslowpan.c working on the Sky platform:
conventional MAC implementations require a call to the MAC driver's
read function.
2008-11-06 20:45:06 +00:00
adamdunkels d73124cc5e Bugfix: there was a problem with TCP segments not being properly retransmitted for protosockets-based applications. Cleaning up the logic around acknowledgements and retransmissions fixed the bugs pertaining to retransmissions of lost packets. This bugfix affects both the telnet server and the web server (which now work as expected wrt packet loss). 2008-10-31 18:10:24 +00:00
adamdunkels f623b81d59 Temporarily out-commented the problematic code and added a comment that describes the problem 2008-10-17 14:40:16 +00:00
mdurvy 75f036f698 uncommented the remove of the router (necessary for compliance) 2008-10-16 09:07:43 +00:00
blakelev 99f6932cdf Removed one line to prevent the default router from being removed
prematurely.  This timer should not time out, but it does.

adamdunkels 31509ad726 Fixed a bunch of bugs in the collection neighbor announcement/discovery code: neighbor announcments were not repeated unless there was a change in the ETX val. Neighbor announcements happened to often when there were changes in the ETX. 2008-08-15 19:00:38 +00:00
adamdunkels 210782d9c6 Set the channel as a packet attribute 2008-08-15 18:59:22 +00:00
adamdunkels 9a4e5dfabf Rewrote the neighbor discovery code so that messages are suppressed if a lower rtmetric is received. This reduces the overall number of broadcast packets. 2008-07-09 09:33:58 +00:00
adamdunkels 9318117429 Fixed function prototype compiler warning 2008-07-08 10:59:31 +00:00
adamdunkels ba5c18a468 Rewrote the trickle code to run directly over the broadcast primitive: the previous implementation did not work as expected, because packets were not supressed correctly by the previous underlying netflood primitive 2008-07-07 23:29:30 +00:00
adamdunkels df33cb6e16 Only send ACK if it was possible to allocate a queuebuf to hold the data packet. 2008-07-07 23:27:57 +00:00

adamdunkels 63c620303a Changed the 'ibc' and 'uc' Rime modules into the more descriptive names 'broadcast' and 'unicast' 2008-06-26 11:19:22 +00:00
oliverschmidt a5fcfa2787 I seem to remember that we wanted to avoid ignoring gcc warnings that might trigger errors with other compilers ;-) 2008-05-16 21:31:57 +00:00

adamdunkels dbab9fbdb5 A quick, initial implementation of the LPP power-saving MAC protocol (Musaloiu-E et al, IPSN 2008) 2008-05-15 08:56:29 +00:00
adamdunkels 1feb4fe3cb Removed call to tcpip_set_forwarding() - the UIP_CONF_IP_FORWARDING configuration option is used instead 2008-05-14 19:20:28 +00:00
adamdunkels 31ea41d8db Changed the name of UIP_CONF_TCP_FORWARD to UIP_CONF_IP_FORWARD since forwarding is done at the IP level 2008-05-14 19:19:28 +00:00

nifi 8d47324d8f fixed typo 2008-04-01 13:22:59 +00:00
nifi fabe4393f7 fixed alignment problem with rime/chameleon 2008-04-01 13:10:22 +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. ***

adamdunkels a0c833da11 Mistakenly included development code in the Makefile target 2008-02-25 13:22:34 +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:

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

This is a rewrite of the code that was developed for the paper.
2008-02-25 02:14:34 +00:00
adamdunkels 974870359a Changed all occurences of u8_t and u16_t to uint8_t and uint16_t 2008-02-24 22:10:30 +00:00
adamdunkels d99ca27820 Changed all occurences of u8_t and u16_t to uint8_t and uint16_t 2008-02-24 22:05:27 +00:00
adamdunkels 3c1b0f4e65 Debug output slightly improved 2008-02-24 21:09:08 +00:00
adamdunkels 16c715aade Updated collect_open() definiton to match prototype declaration 2008-02-24 21:08:37 +00:00
adamdunkels be1dd57cb3 Stopping watchdog before sending packets to allow for wait times longer than 1 second. Reduced default on time to 5 ms. Added option for turning off X-MAC but keeping the radio turned on. 2008-02-24 21:07:28 +00:00
adamdunkels 32a3fa5d4a Added parameter to the mac off() method that specifies whether or not the radio should be turned off when the MAC layer is turned off 2008-02-24 21:05:28 +00:00
adamdunkels 436d1f25eb Added a configuration option for using u32 in the uip_ip4addr_t structure: UIP_CONF_UIP_IP4ADDR_T_WITH_U32 2008-02-24 21:04:15 +00:00
adamdunkels 8c782de931 Ensure that no more data than can be held by the buffer is sent with uip_send() 2008-02-24 21:03:24 +00:00

oliverschmidt 8f81934bfd Since revision 1.11 the usage of the label 'ip_send_nolen' isn't solely depending on UIP_UDP anymore. 2008-02-15 17:12:46 +00:00
oliverschmidt 081d50b878 Reverted part of recent change. The 32-bit member causes 32-bit alignment on 32-bit machines - at least without specific compiler options. That 32-bit alignment causes padding i.e. the ARP structure breaking the existing code. 2008-02-09 16:22:22 +00:00

adamdunkels 2886e03f57 Rewrote the neighbor code to use memb and a list instead of a static array 2008-02-03 20:44:11 +00:00
adamdunkels c576b7b01c Optimized transmission when interval == 0 2008-01-25 01:06:25 +00:00
adamdunkels 6e89e545b3 Added optional transmission of ICMP destimation unreachable in response to incoming UDP packets with an destination port that is not open. This is needed for correct operation of traceroute 2008-01-24 23:08:58 +00:00
