PURPOSE: A wireless optical communication network system, an information construction method, and a relay path determination method are provided to effectively improve wireless communication performance by referring to a reception state as a signal attenuation rate. CONSTITUTION: A destination node receives an optical signal from a light reception unit(S200). A power measurement unit measures the power strength of the optical signal(S210). A state determination unit individually selects the reception attenuation rate of the received signal(S220). The path determination unit of a signal processing unit determines all paths which pass through a relay node(S230). A path state determination unit determines the state of all paths(S240). A path determination unit determines the relay path of a good state(S250).
