Energy-aware offloading for mobile computing with heterogeneous network

Abstract

Computation offloading is widely applied to mobile embedded devices to deal with the challenge of the limited resource of energy and computation. However, the computation offloading introduces extra communication energy and communication delay to the mobile devices and applications. To meet the latency constraint of the applications and maximize the lifetime of the mobile device, an energy-efficient offloading for mobile devices with heterogeneous network interfaces is proposed in this paper. A queuing based estimation dispatcher is presented to minimize the communication energy considering the varied transmission speed of the heterogeneous network. The energy efficiency of the proposed methodology was evaluated and impressive results were obtained.
