SIMULATIONS AND RESULTS
5.1 Simulations
For simulations, we have used ns-3 simulator which is a discrete event network simulator. We have used ns-3 for evaluation of our algorithm for random sensor node deployment scenarios to find the sinks locations for a particular sensor nodes deployment.
We have considered a 4x4 square grid wireless sensor network, where sinks and sensor nodes both are static. Locations of the sinks are deterministically placed. Locations of our sinks are taken from our deterministic sensor node deployment approach for 4x4 square grid region, where the network is 1-hop and 2-covered. Sinks are placed deterministically on grid cross points. But the sensor node deployment strategy is set to random here. Locations of sensor
Here is some screenshots taken of different phases of simulation:

5.2 Results
5.2.1 Section A
As we have seen that, for a wireless sensor networks, to determine the optimal number of sinks needed to meet a certain performance is very difficult task. As it depends on various metrics that was discussed in earlier chapters. We try to show that it is a function of hop-limit, K-covered, transmission range and area of the network.
Number of Candidate sink locations, CA = f (T, M-hop, K-covered, Area).
Here, we present results that we got when we varied some of these parameters:
For transmission range T, 1-hop network and area A is fixed

For transmission range T, 2-hop network and area A is fixed
