The Virtual Machine Migration in Cloud Computing Using Firefly and Gravitational Algorithm

The cloud computing is the architecture in which cloudlets are executed by the virtual machines. The most applicable virtual machines are selected on the basis of execution time and failure rate. Due to virtual machine overloading execution time and energy consumption is increased at steady rate. In this paper, Gravitational technique is applied in which weight of each virtual machine is calculated and virtual machine which has maximum weight is selected on which cloudlet will be migrated. The performance of proposed algorithm is tested by implemented in matlab in terms of execution time, energy consumption.
