Abstract:
1. A multi-hop communication terminal that communicates with a gateway to which the multi-hop communication terminal belongs via a communication route that is an indirect route including at least one other terminal or a direct route, the multi-hop communication terminal comprising: a receiving unit that receives: a routing control unit that determines the communication route based on the received first broadcast signal and the received hello signal; a power control unit that determines a second transmission power value of a data signal in the terminal based on the received first broadcast signal, the received hello signal, and the determined communication route; and a calculation unit that calculates a path loss value between the terminal and a transmission source node of the received first broadcast signal or the received hello signal based on the received first broadcast signal or the received hello signal, and calculates a required transmission power value based on the calculated path loss value and a required receiving power value; wherein when a second broadcast signal is not received from a gateway other than the gateway to which the multi-hop communication terminal belongs, and when the first planned transmission power value is larger than the required transmission power value between the terminal and the gateway to which the multi-hop communication terminal belongs that has been calculated by the calculation unit, the power control unit determines the first planned transmission power value as the second transmission power value.
