HowTo/UsingAODV

@@ +1 @@
+= Using AODV with the testbed =
+
+Currently, we support AODV-UU protocol 0.9.1 on kernel version 2.6.12. Using the application and prototype definition format, we can currently specify 
+ * the interface to run on
+ * enable logging
+ * enable route table logging
+
+
+
+== For Experimenters ==
+ * Step 1: In order to use AODV routing protocol in your experiment, make sure you use the baseline.ndz image on your nodes that has aodv installed.
+ * Step 2: Use the following experiment script. This will launch both the traffic generator and AODV on the nodes. AODV currently logs locally to the node every N secs which is configurable. However, in the future, this will be OMLized to log into the database instead.
+
+'''AODV router prototype and app defs are installed on all consoles. So users should be able to use it from any console'''
+=== Experiment script ===
