Dear all. I am running a very simple test applications where 40 nodes are broadcasting packets every 10 sec, and a BaseStation node is listening to those packets.
And I am receiving far less packets in t2, compared to t1, for (what I believe to be) the same application. So I was wondering whether anyone had experienced shorter radio range in t2 compared to t1. The exact scenario is, 40 telosb nodes, with & without 'CFLAGS += -DCC2420_DEF_RFPOWER=31', on an indoor testbed (http://enl.usc.edu/projects/tutornet/) where node 1~40 are sending broadcasts and node 10 is the BaseStation. I ran experiments several times, for several tens of minutes each time, and tried channel 23 and 26. Also, although I am new to T2, I have some experiences with T1. In T1, I receive packets from 15~20 nodes on average. In T2, I receive packets from 8~12 nodes on average. And the only guess that I can think of (assuming that I've done t1->t2 poring correctly) is shorter radio range in t2 compared to t1.... for some weird reason. is this possible? -- Jeongyeup Paek Ph.D. student Embedded Networks Laboratory Department of Computer Science University of Southern California http://enl.usc.edu/~jpaek _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
