  The user request the creation of two networks on a given set of nodes. Each network will have an access point and a station. The access point and the station are bound by the same essid's and would exist in the same subnet. In the underlying architecture the user chooses the same physical interface on a node to act as a different access point on two seperate networks. The script shows that the user may be oblivious to the fact that he/she is requesting the same node to be acting as different AP's, thereby simulating the requests of two different users for two independent networks with the involvement of a common node (the virtual AP) without each others knowledge. The sample ruby script is as given below:
