Assume the number of sensors is doubled in each cluster. What is the impact on the performance? Explain clearly.
If you double the number of sensors in each cluster, means either the number of sensors n are doubled or the cluster heads m are halved. In either case, the number of sensors per cluster is doubled to 2n/m. So, the net impact is that each cluster head has to collect readings from twice the number of sensors within the cluster. So, energy consumed at each CH may be close to double than the earlier case. If the sensor density is increased, one approach is to divide the sensors into four
groups for sleep- awake cycles. If the density of sensors is not increased, then the sparseness of sensors could be half, doubling the average distance between the CH and sensor members of the cluster. This could force sensor data to be transmitted to twice the distance and could quadruple power consumption per sensor and similar effect can be seen at the CH.
