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.

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

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

8a9b931a4b Rewrote most of the X-MAC code to make it easier to follow, debug and modify. Also added an optional, experimental time synchronized addition that makes X-MACs on different nodes explicitly de-synchronized 2008-01-23 15:00:54 +00:00

bd125aaac6 Changed the code so that the rtimer is only set from the rtimer (interrupt) code, and not from the non-rtimer code. Removed unused code that was supposed to turn the radio off when a packet for another node was heard (but which didn't really work anyway). Changed default on time to 1/100 seconds, and off time to 1/2 seconds 2008-01-14 09:26:42 +00:00

9d4fc0a1a8 Support for z80(sdcc) port.
In order to support, some core modules are modified as follows:

core/sys/dsc.h
- If CTK_CONF_ICONS is diabled, the whole icon-related code is disabled.
- DSC_HEADER is changed to remove extra semicolon.

core/sys/process.h
- process_data_t is expressed by void* in signatures (known bug on sdcc).

core/sys/autostart.h
- autostart_processes is changed to remove extra semicolon.

core/sys/cc.h
- CC_CONF_ASSIGN_AGGREGATE is introduced.
- CC_CONF_INC_CAST_POINTER is introduced, a workaround of a kind
  of sdcc bug for an increment.

core/net/hc.c
core/net/uip_arp.c
core/net/uaodv.c
- Aggregation assignments are changed to uip_ipaddr_copy.

core/net/psock.c
core/net/uipbuf.c
core/net/dhcpc.c
apps/shell/shell.c
core/ctk/vnc-server.c
core/ctk/vnc-out.c
- "register" keyword in a signature cannot be used in sdcc,
  CC_REGISTER_ARG is used instead.

core/net/uip-over-mesh.c
- An extra semicolon is removed.

apps/program-handler/program-handler.c

- $(CLEAN) variable is introduced for customized cleanup.

apps/process-list/process-list.c
- PROCESSLIST_CONF_HEIGHT is introduced to address smaller screen size.

edd509acf5 Added nicer configuration options. Added hack for optimizing X-MAC for unicast packets. Added statistics gathering. Turn radio off when someone else is receiving a packet. Queueing packets when X-MAC cannot send immediately (since someone else is transmitting). 2007-05-22 20:55:24 +00:00
