    39    Any nodes on the grid may be selected as VM nodes. A VM nodes uniquely maps one and only one mobile node.
     39   Any node on the grid may be selected as a VM node. In our system, for each emulated mobile node, there is always ONLY one corresponding VM node.
    4040 * For each VM create a file VM<no>.txt where <no> can take a value from 1 to number of VMs. The first entry in '''listofvms.txt''' has no=1, the next has a value of 2 and so on. In our example we have two VMs, we create '''VM1.txt''' and '''VM2.txt'''. Each '''VM<no>.txt''' file contains two columns. The first column contains time and the second column the grid node that should be mapped to the mobile node at the time. The mapping stays unless the next entry in the '''VM<no>.txt''' changes the mapping. Sample '''VM1.txt''' and '''VM2.txt''' are shown.

    6060In 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.
    61 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.''
     61The mobile node corresponding to VM2 is mapped to node [4,7] on the grid. This mapping does not change.  ''The repeated entry is a adhoc fix. Whenever a VM<no>.txt contains just one entry, the entry must be repeated twice.''
    6262The experimenter needs to ''ensure that at no time more than one mobile node'' be mapped to a grid node.
    6363Only atheros grid nodes are supported.
