摘要：
A determining apparatus (110) obtains distance information that indicates distances between monitoring apparatuses (121 to 128) provided to encompass a given area in which wireless communications apparatuses (102) are scattered. The determining apparatus (110) causes a wireless signal to be transmitted and received between monitoring apparatus (121 to 128) by multi-hop communication among the wireless communications apparatuses (102). The determining apparatus (110) calculates an estimated distance between the monitoring apparatuses (121 to 128), based on the hop count of the wireless signal multi-hop communicated among the monitoring apparatuses (121 to 128). The determining apparatus (110) makes a determination concerning a vacant area (103) in which no wireless communications apparatus of a given area (101) is present, based on the distance indicated by the distance information and the calculated estimated distance.
