Network system bugfixes

Adam Dunkels 82b755c017 Bugfix: keep track of receiver being awake as a local variable rather than a global, as it may have changed between invokations 2013-03-18 11:22:02 +01:00
Adam Dunkels 0670a8e1e2 Minor code style fixes to the contikimac and nullrdc code 2013-03-18 11:22:01 +01:00
Robert Quattlebaum c0a693672c core/net: Added support for "bridge mode".
"Bridge mode" allows devices to more easily send 802.15.4 packets as if
they were a different device. It also turns off any packet filtering
that may be implemented at layer 2. It works by allowing
`PACKETBUF_ADDR_SENDER` to be set earlier in the stack.

This is useful for implementing 6LoWPAN-ethernet bridges.

Enabled via setting `NETSTACK_CONF_BRIDGE_MODE` to 1. Disabled by
default.

Adam Dunkels cb7842bd16 Added support for encryption and decryption of the packetbuf if macros
NETSTACK_ENCRYPT and NETSTACK_DECRYPT are defined. Those are intended
to be called as functions NETSTACK_ENCRYPT() and NETSTACK_DECRYPT() to
encrypt and decrypt the packetbuf, respectively. If needed, an
initialization function by the name NETSTACK_ENCRYPTION_INIT() can
also be defined.

David Kopf 07f6e10c1c Add display options to border router web page, default now uses stack instead of static buffer.
Turn radio off until prefix is acquired.

David Kopf 8e47694597 Add RDC_CONF_HARDWARE_CSMA, RDC_CONF_HARDWARE_ACK, RDC_CONF_MCU_SLEEP, CONTIKIMAC_CONF_SHORTEST_PACKET_SIZE for use with hardware having those modes.
Default behaviour should be unchanged.

Adam Dunkels af4ce9ba9e Bugfix: idle power consumption was sometimes misestimated for transmissions, when a duty cycle rtimer fired in the middle of a transmission 2011-04-13 14:10:02 +02:00
Adam Dunkels 733aaa546f Made the number of MAC sequence numbers to remember configurable; fixed bug with power attribution to the idle state. 2011-02-21 14:11:32 +01:00
Adam Dunkels 46348d9013 Added the low-power streaming mode where frequent channel checks are performed when streaming is on. Enabling this will (by setting WITH_STREAMING to 1), however, significantly slow down Cooja/MSPsim simulations. 2011-02-08 21:57:46 +01:00
adamdunkels d51e99a3dd Updated streaming mode to use only about 20% radio. Made guard time more conservative due to problem report by Ricklef Wohlers. 2011-01-25 14:29:46 +00:00

adamdunkels 79f2c25dae Rework of the phase-lock optimization mechanism. There were several bugs in the existing code, such as the phase-lock would lose synchronization when a packet was lost. 2010-12-16 22:43:07 +00:00

adamdunkels 4c9793f428 Let ContikiMAC remember the state that the radio should have when duty cycling is turned off. This fixes a bug in which the radio was turned on after sending, even when NETSTACK_RDC.off(0) was enabled. 2010-12-06 09:08:22 +00:00
