Abstract

Through analysis of energy consumption of wireless sensor networks with uniform node distribution, this paper finds that energy hole in the wireless sensor networks with uniform node distribution can not be avoided. When network lifetime ends, as much as 90% of network energy remains. However, network lifetime can increase several times by selecting different transmission power levels. The main conclusions in this paper are presented is that the energy consumption in the same circular ring is nonuniform if the density of sensor nodes in the same circular ring is uniform.
