 The ./run script runs all the three tests and counts the number of

-This output shows several this:
-- the number of ACKs in the asymmetric links case is much less than in
-  the equal case which proves the fact that the reverse links are indeed
-  poor.
-- in the unequal case the number on ACKs for node 1 is higher than
-  node 3 which is expected because node 1 has a better link to 2 than 3.
-- in the equal case both nodes perform similar, each of them loosing
-  about half of their packets.
+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.
