Energy Efficient Dynamic Resource Allocation Technique in Mobile Cloud Computing

− Energy consumption of massive scale mobile cloud data centers is increasing unacceptably. It is the most challenging field of concern these days. So there is a need to improve the energy efficiency of such data centers using server consolidation which aims at minimizing the number of active physical machines in a data center. As the analysis has shown that by applying suitable optimization policies directed through our energy consumption models, it is possible to save 20% of energy consumption in mobile cloud data center. Energy crisis has led a way to green computing. Green computing offers various schemes in order to manage the power usage of these data centers efficiently. This paper presents Virtual Machine Placement technique used in green cloud which is a metaheuristic approach. This technique subsequently reduces the energy consumption in the mobile cloud data centers and provides improved server consolidation. Also this paper includes the comprehensive study of the various energy consumption techniques in the mobile cloud data centers and various techniques used for managing high levels of the energy consumption.
