Improved Shortest Remaining Burst Round Robin (ISRBRR) Using RMS as its time quantum
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 8
Abstract
Round Robin (RR) performs optimally in timeshared systems because each process is given an equal amount of static time quantum. But the effectiveness of RR algorithm solely depends upon the choice of time quantum. I have made a comprehensive study and analysis of RR algorithm and SRBRR algorithm. I have proposed an improved version of SRBRR (Shortest Remaining Burst Round Robin) by assigning the processor to processes with shortest remaining burst in round robin manner using the RMS as its time quantum. Time quantum is computed as the root mean square of the burst times. My experimental analysis shows that ISRBRR performs better than RR algorithm and SRBRR in terms of reducing the number of context switches, average waiting time and average turnaround time.
