2 to 3) are much worse (-80 dBm). You should see packet deliveries
like test-equal.py but few acknowledgements.
+The ./run script runs all the three tests and counts the number of
+ACKed and non-ACKed send packets. The output will look something
+like this:
+
+test-equal.log
+ ACK NOACK total
+ 1 21197 19666 40863
+ 3 21320 19543 40863
+test-asym.log
+ ACK NOACK total
+ 1 4930 35923 40853
+ 3 4983 35870 40853
+test-unequal.log
+ ACK NOACK total
+ 1 27619 12966 40585
+ 3 21040 19545 40585
+
+ACK is the number of acknowledged packets from that node to node 2;
+NOACK is the number of unacknowledged packets. Total is the sum.
+The output should show three things:
+
+ 1) In test-equal, both node 1 and node 3 have very
+ similar delivery ratios, losing about half of their packets.
+
+ 2) In test-asym, the number of ACKs is much less than in
+ test-equal because the reverse links are poor.
+
+ 3) In test-unequal, node 1 has more acknowledged packets
+ than node 3, because it has a higher SNR link.
