Abstract: A sink node forming a sensor network system with one or more sensor nodes includes a communication time period allocation means for allocating, to a target sensor node, a communication time period for measurement information transmission by the target sensor node, to not overlap a communication time period for measurement information transmission by a node related to a wireless communication environment between the target sensor node and sink node, concerning measurement information transmission by a sensor target sensor node other than the target sensor node among the one or more sensor nodes. The communication time period allocation means adjusts a communication time period allocated for subsequent measurement information to be transmitted by the target sensor node, based on a predetermined wireless communication parameter related to the wireless communication environment between the target sensor node and sink node, concerning measurement information transmission by the target sensor node.
