Re: [Tinyos-help] topology and linkgain.out
Hi, I believe that the topology generation tool generates one value of noise to be consistent with an older version of TOSSIM. The way the current version is intended to be used is that you collect a noise trace in your environment (at least 100 samples long) and then input this trace into the simulation. There is an application tinyos-2.x-contrib/stanford-sing/apps/RssiSample that will accomplish this. However, if it is not possible to collect noise samples, one possible simplification is to repeat the constant noise value from the generator 100 times. This will mean that the link model will assume a constant noise value. However, this will lower the quality of the link simulation. You can also use the example provided, meyer-heavy.txt. Thanks, Tal hello I've generated the two files linkgain.out and topology.out with LinkLayerModel. Topology.out give me a file with the gain between all pairs of nodes and the noise for each node. But , for the noise it give me only 2 values, how can I use these values with the addNoiseTraceReading function ? I know that it must have at least 100 entries using the addNoiseTraceReading function.

If you look at apps/tests/TestNetwork, you will notice that the application puts the parent id in the collection packet. You need to do something similar in MultihopOscilloscope. When you receive that collection packet at the base station, you can grab the parent id and origin for each node. Once you have a set of directed edges, you can use graphviz or other graph drawing tools to draw the topology. - om_p ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

Frankly, I can come up with the topology, but I cannot get much information from this topology. That is, I do not think this topology is very useful. Any comments about this are appreciated. The topology could be useful to debug your network - for example, if you are getting 10 hop paths in a small room, or if the topology is changing a lot, that is probably not a good sign... - om_p ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

[Tinyos-help] topology control (e.g XTC, ATPC, LMST)
Hi all I am looking for the tinyos implementation for any topology control such as XTC. Thanks. Paul ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] Topology
Hello. I wrote a small program that defines events for an active node. It compiles in TOSSIM. I am having trouble defining a topology. In the Active folder, I have a Topo.txt file with contains the following (node, x, y): 0 1.0 1.0 1 1.0 10.0 I get the following error when trying to identify the topology file: TOPOLOGY = 4 TOPOLOGY_FILE = Topo.txt Traceback (most recent call last): File stdin, line 1, in ? NameError: name 'Topo' is not defined Thank you very much.
