Abstract:
Limited energy is the major driving factor for research on wireless sensor networks. Clustering alleviates
this energy shortage problem by reducing data traffic conveyed over the network and therefore several clustering methods
are proposed in the literature. Researchers put forward their methods by making serious assumptions such as always
locating single sink at one side of the topology or making clusters near to the sink with smaller sizes. However, to the best
of our knowledge, there is no comprehensive research that investigates the effects of various structural alternatives on
energy consumption of wireless sensor networks. In this paper, we thoroughly analyze the impact of various structural
approaches such as cluster size, number of tiers in the topology, node density, position and number of sinks. Extensive
simulation results are provided. The results show that the best performance about lifetime prolongation is achieved by
locating a sufficient number of sinks around the network area.
