Abstract

The problem of energy efficiency due to the limited resources in Wireless Sensor Networks (WSNs) has made cluster-based architectures widespread use in these networks. The studies in literature regarding WSNs aim to make efficient use of battery in network by different methods such as using different parameters in cluster head selection, time-based cluster head election or clustering with artificial intelligence algorithms. The coverage area of clusters is selected in a range that can cover the whole network in some studies, while it is limited in others. In this study, the effect of the cluster-head coverage area parameter on the lifetime of the network is investigated with detailed simulations. The death of the first, middle, and last node are reported by using different numbers of nodes, coverage areas, and network sizes. According to the results obtained, the increase of the cluster coverage area causes the first node deaths to be delayed and the middle and last node deaths to occur earlier. The increase of the network area takes all the node measurements at an early cycle while the first node is at the highest level and the last node at the lowest level. As the number of nodes increases, the first node deaths are delayed to an earlier cycle, while the middle and final node deaths are delayed. In the light of the results obtained, it is thought that this study will help the cluster coverage area to be selected according to the design preferences in clustering based architectures that will be designed both in real time and in the simulation environment in future.
