This study focuses on how to optimize the communication radii of sensor nodes in hierarchically clustered sensor networks to minimize the total energy consumption. The energy model is E=a(dα+c), where R denotes the range of sensor networks and K is the number of layers. When the radii of sensor nodes are fixed, the upper bound of the optimal radii of sensor nodes is proved to be α c/(α-1) if α=2,c≤4R2, or if α=4, c≤4R2,K≤ 6 R. When the radii are adjustable and α=2, the radii are obtained by minimizing the average energy consumption layer by layer.
