Fábio Diniz Rossi

Dear Dalia,

Cloudsim is not an application-level simulator (response time, security, etc. are application-level metrics). This simulator addresses only infrastructure layer (VM, Hardware, etc). But, you can treat each cloudlet as an user request, because each cloudlet has a time completion. Based on that, you can interpret this time as the response time.

See a paper which name is given below:

Quality-of-service in cloud computing: modeling techniques and their applications

Danilo Ardagna, Giuliano CasaleEmail author, Michele Ciavotta, Juan F Pérez and Weikun Wang

Pradeep Tiwari

Use the cloudlet to send the request as per (UB)userbase to DC(datacenter) and calculate the response time and throughput by using the formulas. Time calculation may be ms to hr. Its depend on load and availability. Also use cloudsim with cloud analysis tool

Mohammad Sadegh Aslanpour

Yes, you can.

I have done it and you can see my papers.

You should calculate cloudlets' response time by controlling events in CloudSim.
