So, you want three instances of collection? One for each cluster and one for the entire network? so i'm thinking to build a generic collection module that use AM ID as parameter. so i can build different tree... it will be faisible or is there something under this module that i'm missing that can be an obstacle?

yeah, i made a typo in my question (more than one, i see), but you've right understood however. now i have another question: doing as you suggest to me, it's better to work on a modified version of the already existing CollectionC module or it's better to take the basic components and write/wire a new component from scratch. anyway, that's a bad news for me, because i've based a more than a month work for my thesis on this idea (different-id == different roots).

You have five motes? Node 1 and 3 will measure the ambient temperature and send it the the leader of their respective area (using the collection sender) so node 1 will send its data to node 0 and node 4 to node 3 I think there is a typo here - is node 3 your root? This is (my) exptected behavior. THE PROBLEM: but this case sometimes work and sometimes not. both temperature nodes sent their data (connecting them to the pc i can see their printf ) node 0 and 2 indeed, sometimes both thei receive the data, sometimes only one of the two. INFO i'm using the tinyos 2 from CVS 4 tmotesky motes i attach the files of the application ANSWER?! am i missing something about the collection protocol? what can i check to understand what is failing? why sometimes work and sometimes not? The argument you pass to CollectionSenderC during its instantiation is protocol id, the dispatch id of the protocol or application running on top of CTP. So, you are not forming two separate/disjoint trees. If you want two disjoint trees, you should run one instance of CTP in one part of the network and another instance of CTP in another part of the network. To do this, you can run CTP on two different AM types. Otherwise, you will have multiple roots in the same network and the packets will go to any or all of the roots depending on the dynamics or topology. - om_p ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
