摘要
科技的进步使得智能移动设备越来越普及化,移动设备流量急剧增长。但智能移动设备由于自身资源及计算性能有限,在处理计算密集型和时间敏感型应用时可能会面临能力不足的情况。将移动终端需要处理的计算卸载到边缘网络中的计算节点进行计算,能有效解决此问题。基于移动边缘网络介绍了已有的计算卸载策略,从最小化延迟、最小化能耗、最大化收益这几个方面进行阐述,对比了不同侧重点的卸载策略的优缺点,并对移动边缘计算卸载策略的未来发展进行了思考与展望。
Improvement of technology makes smart mobile devices more and more popular.Mobile device traffic is growing rapidly.However,due to the limited resources and computing performance of smart mobile devices,mobile device may face the situation of insufficient capacity when dealing with compute-intensive and time-sensitive applications.Unloading the computations which the mobile terminal needs to process to the computing nodes in the edge network for calculation is an effective way to solve this problem.This paper first introduced the existing calculation offloading strate-gies and elaborated from the aspects of minimizing delay,minimizing energy consumption and maximizing benefits.Then,it compared the advantages and disadvantages of different offloading strategies.At last,it considered and prospected the future development of calculation offloading strategies of mobile edge network.
