fros4943 0034fd7bca generic return values for sent packet 2009-11-13 10:09:02 +00:00
fros4943 9b20f11cd8 chameleon returns 1 only on successful rime_output() 2009-11-13 09:14:52 +00:00
fros4943 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
2009-11-13 09:10:24 +00:00
fros4943 26bb5ecd21 added radio and MAC generic return values to allow applications finding out whether the packet was transmitted 2009-11-13 08:59:22 +00:00

adamdunkels 70fc23ac7e Enable stream mode by default, remove LED debug mode 2009-11-04 16:02:45 +00:00
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.

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.

adamdunkels 9ec57d61ad Added MAC layer framing support to X-MAC so that packets now are standard 802.15.4 frames 2009-10-19 20:53:56 +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.

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.

adamdunkels 02734c9806 Bugfix: must copy the sender and receiver addresses from the packetbuf buffer, otherwise an application program may overwrite them 2009-05-10 21:10:02 +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 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 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
