Scheduling is a fundamental operating system task. Simulation environment are used to study the behavior of scheduling algorithms. A simulation environment is developed for building and studying operating system software .The efficiency of the CPU scheduling algorithm in a multiprogramming system is the most important consideration. The real time operating system supports applications that should meet the time deadlines. To meet the constraints of the application in a real time for scheduling the task different algorithms are used. The main characteristics for the scheduling algorithms are IO throughput, waiting time, CPU utilization, response time, priority and total time required.The main objective of this paper is to compare the different scheduling simulators according to the above mentioned characteristics. By comparison we have illustrated features, advantages and disadvantages between various simulators.
