I am facing a situation where , I use the TestNetwork Application in testbed
of about 45 telosb motes. I was trying to check the saturation point of ctp.
I increased the packet rate to some 1 packet per second for about 15 nodes
and  one packet every 8s for
the rest 20 motes. I still have a very good delivery ratio of about 98
percentage.
How much of data rate is ctp supposed to handle?
 When I went down to 3packets /sec for the 15 nodes and one packet /8s for
the rest of the nodes , then was only significant drop in the delivery ratio
to about 74 percent.
I think the results I got are not accurate? i do not know if I did something
wrong here?
Please leave your insight.
