5f71e9914e configurable line buffer size + simplified interrupt handler + overflow check on line buffer 2009-11-02 12:47:06 +00:00

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.

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.

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.

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.
