Experiment done in an open parking lot.

Number of nodes = 11

Locations = [1.0 14.0 3.0 21.0 9.0 22.0 10.0 3.0 27.0 20.0 18.0;
	     7.0 3.0 19.0 18.0 33.0 3.0 11.0 32.0 27.0 12.0 34.0];

First Row represents the x-coordinates of the nodes, and the second row represents the y-coordinates. All values are in feet.

The RSS Values matrix is a 11x11 matrix where an element at position (i,j) represents the RSS value at node i due to a packet recieved from node j. All values are in dBm. The diagonal elements, reading -100.00 have no physical meaning (as a node cannot receive from itself in this half-duplex radio).

Measurements are from Mica2 motes.
