Hi, You can have a look in the Collection component of tinyOS 2. It implements a control plane for building the tree. But the tree is not binary.

hi, I'm trying to implement an algorithm for the aggregation of data collected by sensor nodes. As part of the implementation we have a certain no. of nodes reporting sensed values to aggregation nodes which form a tree. Are there any TinyOS applications that might already be building a tree using sensor nodes. Essentially I need some sort off Handshaking (sequence of BEACON, PROBE & JOIN messages) between nodes and for a binary tree to be formed as a result. If someone could throw some light as to how I could go about doing this incase there aren't any developed components that I could use, I would be extremely grateful. To that effect I know that using defferent handler ids I could differentiate the 3 msgs. However, I'm concerned abt. specific issues like when how a node would deal with a situation where a parent node tries to join its own child node as a child. thanks, prem _______________________________________________ Tinyos-help mailing list [email protected] https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
