If you install these applications on the motes, the motes will send data over multiple hops to the sink. - om_p ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] Multi-hop Application
Thanks a lot for your reply. I installed the multihopLqi application on three motes giving node id as 500(for root), 1 and 2. I reduced the transmission power of the tmotes to happen multi-hop inside a room. But i found only the data from the closet mote to the root is getting collected. Could any one please let me know if i am doing anything wrong?

You might have to move the motes closer to each other. This might work: Lets say you want three motes to form a multihop topology. Program one mote as root and two motes as non-root. Put the root at position A. Move one non-root mote farther from position A until you start seeing a drop in delivery ratio for packets from that mote. Mark that position as B. Then start moving the last non-root mote away from position B until you start seeing a drop in delivery ratio (position C). As you move the mote, first it might send the packet to the root directly, then it will send the packets via the non-root mote at B. This procedure might give you a rough idea on where you should put the motes (A,B,C) to form multihop topology. - om_p ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] Multi-hop Application
Thanks Omprakash I was configuring the multihop in the following way. Suppose A is the location of the root. B is the location of the one non-root node which is in the radio range of root node(Placed at A) C is the location of the another non-root node which is in the radio range of non-root node(placed at B) but not root(placed at A). Is it a problem? Thanks Rajat On Mon, Sep 28, 2009 at 1:27 AM, Omprakash Gnawali wrote: > On Fri, Sep 25, 2009 at 9:51 AM, rajat_315 wrote: > > > > Thanks a lot for your reply.

It is not a problem but you will have to experiment with distances and transmit power to get it right. - om_p ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
