Moving distances (2000 m × 2000 m). This figure shows the moving distances yielded when the sensing area is 2000 m × 2000 m, where the numbers of sensor nodes are 10, 20, 30, 40 and 50. We evaluate the performances of five schemes. The back-routing avoidance method is not included in the CCPPA_A and ICPPA_A. In contrast, the CCPPA_B and ICPPA_B execute the function for back-routing avoidance
