Laurent Deru 68c284b955 Do not add a CRC to packet incoming from RfListener 2015-06-16 10:36:33 +02:00
Timofei Istomin eb4bdde9ca Finish the transmission at the end of a correct packet
This patch restores the original behaviour of Cooja when
the transmitted packet is correct (which is true in a vast majority
of cases).

In case of a wrong outgoing packet (wrong length, wrong preamble)
the transmission will end when the radio changes its state (which
should always happen after transmitting a packet).

Benchmarks with RPL (33 runs, 50 nodes, 3 hours of simulated time each)
yield the same results (PDR, delay, number of transmitted packets)
as with the unmodified Cooja.

Timofei Istomin 034a97eed2 Don't generate a zero-length packet in case of errors.
The packet converter used to generate packets of length zero
when it encountered errors during conversion. This caused
exceptions in packet analyzers.

Now the converter returns null in case of error. Appropriate
checks have been added to the code that uses the return value.

Improve multichannel support in Cooja

Timofei Istomin eae25d622d Check the frame preamble and MPDU length before parsing
Due to errors in mspsim and/or radio drivers, packets of incorrect
length are sometimes transmitted. The length might be larger than
the 127-byte maximum (considered negative in the current code)
or not matching the actual number of transmitted bytes.
This leads to wrong packet delimiting when converting from
the mspsim-level stream of bytes to Cooja-level packets
causing unhandled exceptions that terminate the simulation.

This patch checks the frame preamble (0000007A) and the length field.
If they are wrong, no decoding attempt is done.

The transmitted bytes are still delivered to the receivers untouched.
The connection is terminated when the radio state is changed (which alway
s happens when TX is done).

Atis Elsts 67427b9b86 Improve multichannel support for Cooja.
* Fix CCA detection in Cooja in the case when the receiver swicthes on the right channel during an ongoing transmission. Always add a connection on transmission, even when the channel is not correct. Initially the connection is in a dormant state; this mimics what Cooja is doing when the receiver radio is turned off;
when the receiver is turned on and switched to the right channel, `updateSignalStrengths()` is called, and the connection starts to recieve PHY-level traffic.

* Add "channel" property for DGRM edges.

* Avoid cross-channel interference on DGRM and MRM radio mediums

Enrico Joerns 0a63922fa2 Buttons: Move implementation of button routines to Button class
The implementation of clickButton(), pressButton(), and releaseButton()
can be shared accross the several node-dependent implementations as
they use the node-dependent doPressButton() doReleaseButton() routines.
2014-11-04 01:48:12 +01:00
Enrico Joerns be88a4fc52 Button: Add doPressButton() and doReleaseButton() to Button class
As every Button has a node-specific implementation part, this should be
the minimal interface to the backend node emulator for pressing and
releasing a button.

Enrico Joerns 378ca2629d Button: None of the buttons will saves its state
Saving a buttons state in simulation file is not required as its state
is much too volatile.

duplication accross the several button implementations.

Enrico Joerns 9d27b181c1 [cooja/mspsim] Msp802154Radio: Fix maximum power indicator
Previously getOutputPowerIndicatorMax() returned the fixed value 31.
This is valid for e.g. the mspsim CC2420 radio implementation but not for the CC2520 implementation where the maximum returned value is 9.

Thus to fix transmission range issues (for example for Wismote node) the maxium value provided by the radio implementaiton must be used.
