In this dataset, we provide the logs of the simulations for the cases studied in the paper: Centralized Energy Prediction in Wireless Sensor Networks Leveraged by Software-Defined Networking. There are two folders, one for the case where the Markov chain runs in every node (results_MARKOV_Node), and the second one where the Markov chain runs in the SDN controller (results_MARKOV_PC). controller_Energy_test_n#nodes_topTEST_ENERGY_i#iteration.txt: Log of the SDN controller Energy_test_log_n#nodes_topTEST_ENERGY_i#iteration.txt: log of the COOJA simulator Energy_test_n#nodes_topTEST_ENERGY_i#iteration.txt: Motes outputs
