Fig. 13 shows the confidence interval for different (N, H) parameters at 50%, 90% and 95% probability level. Fig.14 shows the comparison of confidence interval at 50% probability level between two network architecture with similar network size. The metric of confidence interval has revealed that N=5, H=3 is more reliable since the interval of 28.5% - 60% is higher than the case of N=3, H=4. This demonstrates how two different WSN topologies can be compared and chosen based on the estimation of collected data.
