Hi all, firstly, sorry about my english, this is not my first language;) My name is Mario and i've been working with tinyOS for a few months, but I have something to do and i wonder if there any designed protocol for this. We have two sorts of nodes on the network: the "main" node, connected to a PC via UART, and the "slaves", a lot of nodes that are sending information to the main node (the actual temperature, for example). OK, the protocol has two main tasks to complete; the first one is to "collect" all data in the main node one time per min; of course, i'm using "ctp" for this task, and it seems to work pretty well (I must do more tests). But the other one is that the slave nodes has to receive packets from the main node, this packets have to been sent to a concrete node, not all, and, because of the separation between tx and rx, I need a protocol that handles multi-hop (i can't just sent it via broadcast). Is there any protocol that do what I want? It would be perfect if CTP sent packets to the opposite direction...
Any idea? Thanks all!
