Energy Consumption Management using Fuzzy Logic in Distributed Systems Environment
Elham Haririan,Amir Masoud Rahmani 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.8
Cloud computing has based on on-demand access to potentially significant amounts of remote datacenter capabilities in distributed systems environment. By propagation data centers in clouds, computers should have a lower energy consumption. Hence, a good prediction about the amount of needed resources is very helpful for correct decision on energy consumption management. In this paper the Fuzzy Logic approach has been used for decision making about the performance of processors to obtain the estimated amounts of energy consumed by them and have been applied Auto Regressive and Neural Network approaches to predict the future workload. In prediction operation, three modes On, Off and Idle are considered for each server. At times of peak demand all servers must be turned on but when consumption is low, an estimated number of servers that must be turned on is obtained, 10% of remaining servers are idle and others are off. In this case a significant amount of energy is saved compared to the case that all servers are clear. The result show that Neural Network approach has more accurate prediction and better performance than Auto Regressive model.
