The next test involves the same software and three compatible motes, defined in the first experiment.
Set up the three motes as before (in a triangle, 1 m apart). Two will remain fixed, one will be moved relative to the other two. In each position let the motes communicate for 2 minutes and record the number of attempted connections, the number of successful connections, the average signal strength and its standard deviation.
Move the mote in the horizontal plane 360 degrees in increments of 30 degrees (12 trials).
Move the mote in the vertical plane 360 degrees in increments of 30 degrees (12 trials).
Move the mote in a direction bisecting the other two motes in increments of 10 cm over a distance from the point between the other two motes to a point 2 m distant from that position along a line perpendicular to the line between the other two motes (20 trials).
