One should keep in mind that running the different images should maintain consistency and integrity. Further, it is often needed to run the simulations again and again by creating different trace files. The scripts to obtain the useful parameter from the trace file depends on the researcher and his/her needs. However, one may provide a facility for running the same simulation in terms of images over the cloud and generate trace files with different seeds so that on may extract the information according to one's own need and then take the average over all those trace files generated by different images.

yes @Ash Abbas , that's exactly what i am planning to do . But i wanted to know whether ,and how, can this be achieved using OpenStack.

Yes it is

Yes, it's an easy way to do, but needs a good referenced guide as told by Ash Abbas. Anyway, be a nice research.

Nothing special, should be pretty straightforward.

Thank you for all your replies .

@vedran and @carlos , can you guys please give me some good reference where i can begin this with?

How can i provide for the network simulations once i create the Openstack Cloud?
