Dear Ehsan,

I think you are a beginner in cloudSim, If you are expert in java you will learn it easily. but I recommend you to read cloudSim manuals first. Algorithms that you want are very easy to implement. These links may help you:

http://www.buyya.com/papers/CloudSim2010.pdf

http://www.cloudbus.org/cloudsim/

http://www.tipy.ir/cloudsim-tutorial-introduction.html (Farsi)

https://www.youtube.com/watch?v=MA6L3OQqp10

By the way, the default scheduler in cloudSim is FCFS.

Sambit Kumar Mishra

Hi Ehsan,

There are some examples in the CloudSim simulator. After creation of tasks (Cloudlets) and VMs, all are submitted to the CloudletList and VMList respectively. Then, the allocation of tasks to VMs is taking place. In this place, you can put your algorithms (RR, SJF, etc.) and the default scheduler in cloudSim is FCFS.

Ehsan Shojaeian

thank you for answer to my question. do you have pseudo code of FCFS, RR, SJF?
