DROO

Deep Reinforcement Learning for Online Computation Offloading in Wireless Powered Mobile-Edge Computing Networks

Python code to reproduce our works on Wireless-powered Mobile-Edge Computing [1], which uses the wireless channel gains as the input and the binary computing mode selection results as the output of a deep neural network (DNN). It includes:

• memory.py: the DNN structure for the WPMEC, inclduing training structure and test structure

• data: all data are stored in this subdirectory, includes:

  • data_#.mat: training and testing data sets, where # = {10, 20, 30} is the user number

• main.py: run this file for DROO, including setting system parameters

• demo_alternate_weights.py: run this file to evaluate the performance of DROO when WDs' weights are alternated

• demo_on_off.py: run this file to evaluate the performance of DROO when some WDs are randomly turning on/off
