We evaluated the size of the overlapped area, S (the total intersection area) among the four sensor nodes with different r values using our derived equation (11) with r set to 10 meters. When k was set to 1 (distance from the center point of C1 to the intersection point with C2 is equal to radius r) produced the largest overlapped area. When k set to 0.5, the computed overlap area was 132.27m2. This value gets smaller as the k value increases. The minimum overlap area of 83.43m2 is reached when k is 0.785. Thereafter, we observe that the size of the overlap area increases almost exponentially reaching the maximum of 228.31m2 when k = 1 |
