Server Energy Consumption Model Based on ConvLSTM in Mobile Edge Computing

针对现有能耗模型对动态工作负载波动具有低敏感性和低精度的问题,该文基于卷积长短期记忆(convolutional long short-term memory, ConvLSTM)神经网络,提出了用于移动边缘计算的服务器智能能耗模型(intelligence server energy consumption model,IECM),用于预测和优化服务器的能量消耗。通过收集服务器运行时间参数,使用熵值法筛选和保留显著影响服务器能耗的参数。基于选定的参数,利用ConvLSTM神经网络训练服务器能耗模型的深度网络。与现有的能耗模型相比,IECM在CPU密集型、I/O密集型、内存密集型和混合型任务上,能够适应服务器工作负载的动态变化,并在能耗预测上具有更好的准确性。

To address the issue of low sensitivity and accuracy of existing energy con-sumption models in accommodating dynamic workloadfluctuations,this paper proposes an intelligence server energy consumption model(IECM)based on the convolutional long short-term memory(ConvLSTM)neural network in mobile edge computing,which is used to predict and optimize energy consumption in servers.By collecting server runtime param-eters and using the entropy method tofilter and retain parameters significantly affecting server energy consumption,a deep network for training the server energy consumption model is constructed based on the selected parameters using the ConvLSTM neural net-work.Compared with existing energy consumption models,IECM exhibits superior adapt-ability to dynamic changes in server workload in CPU-intensive,I/O-intensive,memory-intensive,and mixed tasks,offering enhanced accuracy in energy consumption prediction.
