PROBLEM TO BE SOLVED: To simultaneously design the number of relay nodes installed, the installation location and the data transmission route so that the total cost of installing and operating a wireless sensor network is minimized. SOLUTION: Under the condition that the replacement work or repair update work of the power supply source of the sensor node and the relay node is carried out together with the periodic inspection, the installation location of the relay node and the gateway, the transmission output of each sensor node and each relay node. It is a wireless sensor network design method that simultaneously determines the level, the type of power supply source of each sensor node and each relay node, and the data transmission route by finding the solution of the optimization problem, and is an optimization problem. The solution of is to minimize the objective function under the given constraints, which is the power consumption cost for each power source at each sensor node and each relay node, and the installation for each power source. Includes costs. [Selection diagram] Fig. 1
