The relative statistics of energy consumption of the scenarios in Fig. 11: the relative mean (or standard deviation) of DGSI-FEM (or GEAR) is defined as the mean (or standard deviation) of the routing energy consumption of DGSI-FEM (or GEAR) divided by the mean (or standard deviation) of the routing energy consumption of GPSR. a The relative mean of the energy consumption. b The relative standard deviation of the energy consumption
