VirtualMachine vm = new VirtualMachine(i, brokerId, vmMips[i], penum, draml, bandW, storeSize, vmm, sched);

broker = new CreatedBroker(“Broker”, usid);

cloudlet = new NewCloudlet(x, cloudLength[x], pecount, cloudIn[x], opsize, utilizationModel, utilizationModel, utilizationModel);

Get user requirements in terms of number of cloudlets and configuration of each cloudlet.

getAppConfiguration();

getTotalCloudlet();

Normal user submits the average number of cloudlets. Attacker user submits larger number of cloudlets.

broker.submitCloudletList(newList);

lastClock = CloudSim.startSimulation();

Applist = broker.getCloudletReceivedList();

printCloudletList(Applist);

Print the execution time of the cloudlets. Execution time of cloudlets gets increased due to the overloading of VMs in host due to the DoS attack.
