    For the purpose of illustration let us assume that we want to emulate two mobile nodes on the grid. Each mobile node has to be associated with a VM, an association that will stay throughout the experiment. Select nodes [3,6] and [5,6] on the grid. The corresponding entries in the file '''listofvms.txt''' are shown below.

+In the example mobile node corresponding to VM1 is mapped to nodes [4,1], [4,3], [4,5] at intervals of 5 seconds. The mapping is repeated and the total experiment time is 60 sec after which the mobile node is fixed to node [4,1] on the grid.
+The mobile node corresponding to VM2 is mapped to node [4,7] on the grid. The mapping doesn't change.  ''The repeated entry is a adhoc fix. Whenever a VM<no>.txt contains just one entry, the entry must be repeated twice.''
+The experimenter needs to ''ensure that at no time more than one mobile node'' be mapped to a grid node. 
+Only atheros grid nodes are supported.
+ * Run the script CreateMobilitySetup once you have populated the files listofvms.txt and VM<no>.txt(s).
+{{{
+$ CreateMobilitySetup

+Click files/scripts are generated in the EthernetAddresses directory. A click file/script is generated for each VM. Also a click file is generated for each grid node which is mapped to a mobile node at a certain time during the experiment. Files corresponding to VMs are of the name mob_server_src_generated_VM<no>.click. Those corresponding to mapped nodes on the grid are of the name mob_node_src_generated_Node_<x>_<y>.click where [x,y] is the grid co-ordinate of the node mapped. The list of files generated for our experiment are listed below.

+ * Image all grid nodes (VM nodes and the nodes mapped to mobile nodes) with the image click-2.4.26-20051204.ndz.
+ * Upload the click files onto the grid nodes they correspond. The file '''loadFiles.sh''' contains sample commands for the example experiment.
+ * For each node install the click script. On nodes specified in the VM<no>.txt(s) it is important that the ath0 interface is up.
