In this paper, we propose a new energy efficient clustering scheme with transmission power control named "EACLE" (Energy-Aware CLustering scheme with transmission power control for sEnsor networks) for wireless sensor networks, which are composed of the following three components; "EACLE clustering" is a distributed clustering method by means of transmission power control, "EACLE routing" builds a tree rooted at a sink node and sets the paths from sensor nodes taking energy saving into consideration, and "EACLE transmission timing control" changes the transmission timing with different levels of transmission power to avoid packet collisions and facilitates packet binding.With an indoor wireless channel model which we obtained from channel measurement campaigns in rooms and corridors and an energy consumption model which we obtained from a measurement of a chipset, we performed computer simulations to investigate the performance of EACLE in a realistic environment. Our simulation results indicate that EACLE outperforms a conventional scheme such as EAD (Energy-Aware Data-centric routing) in terms of communication success rate and energy consumption. Furthermore, we fully discuss the impact of transmission power and timing control on the performance of EACLE.
