This paper proposes a novel transmission power-control method for power-saving in consensus problem. Focused consensus problem is an average-consensus where all agents try to assemble in the same position. Thus, in the process of consensus, the distance among agents becomes closer. Consequently, there is the gap between the maximum communication coverage and the distance to the farthest neighbor agent, which results in the waste of transmission power. This paper focuses on this fact and proposes the power-control method based on the position of neighbors. To keep the quality of control, we further propose the transmission power-control. The computer simulations showed that the proposed power saving can save the power consumption up to 1/5 but keep almost the same control quality as the system without power-saving.
