Abstract

The term offloading indicates the action of changing the processing location of a computational activity. The purpose of using offloading is to reduce the processing time of applications, reduce the power consumption of the devices and eventually enable the execution of tasks that would not be possible on devices with reduced resources. This paper presents an offloading framework, called MLOOF, for smartphones and IoT devices. The offloading process is done from the devices to nearby servers (cloudlet), which enables the reduction of latency and increase in network throughput when compared to the offloading to servers in the cloud. The system was evaluated experimentally and the results show that the strategy of offloading in three levels achieves the goals of reducing processing time (up to 74%) and energy consumption (more than 90%).
