[Tinyos-help] send unicast message using multihop communication method

[ලසන්ති]

hi,
i am doing a project which needs to send messages to specific nodes. Simply,
need to send unicast messages. for example, node A may want to send a
message to node B, while another node C wants to send a message to node D.
but they are not in senders transmission range and because of this reason, i
cant use AMSend.send() with the destination node id. So, i guess i have to
use mutilhop communication. Am i correct? or is there any otherway to
achieve my requirment.

I followed the MultihopOscilloscope application and now i know how to send a
message using multihop transmission method. But, if i understood that
correctly, any node can send a message to a node which is set as the Root.
any node can set itself as a Root but others cannot set other node as a
Root. Also i know that there could be multiple Root nodes.

Can anyone give me an hint how to do a unicast to a specific node.

Thanks.
Lasanthi
