In a wireless multihop network, collision between a routing control message and an information collection message is avoided, and information collection is completed within a predetermined time. A terminal includes: a transmission period control unit that calculates transmittable periods of a routing control message and an information collection message per hop, based on a hop count from the sink node and the number of terminals per hop, calculate a collision period during which the routing control message collides with the information collection message, based on both of the calculated transmittable periods, and recalculates the transmittable period of the routing control message so as to transmit the routing control message while avoiding the calculated collision period; a routing control unit that creates and transmits the routing control message within the transmittable period of the routing control message according to a hop count of the terminal; and an information transmission unit that creates and transmits the information collection message within the transmittable period of the information collection message according to a hop count of the terminal.
