Moving distances (5000 m × 5000 m). This figure shows the moving distances when the sensing area is 5000 m × 5000 m and the numbers of sensor nodes are 50, 100, 150, 200 and 250. 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
