Abstract

Abstract:

As the popularity of smart mobile terminals increase in recent years, mobile applications are becoming more diverse and complex These applications require large amounts of computing resources and energy. Therefore, there is an urgent need for new technologies capable of improving the computing performance and battery life of mobile terminals. Orienting to LTE, an energy efficient computation offloading strategy for mobile terminals is proposed which can be used in mobile cloud environment. By taking the transmitting power and CPU speed as constraints, the strategy analyzes requirements of an application program, the mobile terminal 's computing power and the status of fading channel; afterwards it optimizes the transmitting power and CPU computing resources sensibly. It can minimize the mobile terminal 's energy consumption by implementing reasonable computation offloading. Simulation results show that the proposed strategy can save a mobile terminal 's energy consumption, and it does not bring obvious additional delay simultaneously.

Key words: smart mobile terminal, mobile cloud, computation offloading, minimizing energy consumption
