A management apparatus for managing a wireless network (N1) adopting a Time Division Multiple Access, TDMA, wireless communication using communication links among wireless devices, the management apparatus comprising: a storage storing unset communication links other than previously set communication links for the wireless communication via the wireless network (N1) among communication links previously prepared in hopping patterns, HP; and a manager configured to divide each unset communication link stored in the storage to provide a plurality of communication links, each of which includes information indicating an interval between time slots during a cyclic communication in the TDMA wireless communication, to set the plurality of communication links in accordance with a setting request of communication links and to assign a priority in accordance with a previously defined rule to the divided communication link; wherein the management apparatus is configured thus that: when the manager forms a plurality of communication links having a same interval, the manager is configured to assign a higher priority to each of the plurality of communication links as the priority of the communication link, which is divided to form the plurality communication links increases; and when the manager repeatedly divides a single communication link to form a plurality of communication links, the manager is configured to assign a higher priority to each of the plurality of communication links as the interval of each of the plurality of communication links increases. a storage storing unset communication links other than previously set communication links for the wireless communication via the wireless network (N1) among communication links previously prepared in hopping patterns, HP; and a manager configured to divide each unset communication link stored in the storage to provide a plurality of communication links, each of which includes information indicating an interval between time slots during a cyclic communication in the TDMA wireless communication, to set the plurality of communication links in accordance with a setting request of communication links and to assign a priority in accordance with a previously defined rule to the divided communication link; wherein the management apparatus is configured thus that: when the manager forms a plurality of communication links having a same interval, the manager is configured to assign a higher priority to each of the plurality of communication links as the priority of the communication link, which is divided to form the plurality communication links increases; and when the manager repeatedly divides a single communication link to form a plurality of communication links, the manager is configured to assign a higher priority to each of the plurality of communication links as the interval of each of the plurality of communication links increases. when the manager forms a plurality of communication links having a same interval, the manager is configured to assign a higher priority to each of the plurality of communication links as the priority of the communication link, which is divided to form the plurality communication links increases; and when the manager repeatedly divides a single communication link to form a plurality of communication links, the manager is configured to assign a higher priority to each of the plurality of communication links as the interval of each of the plurality of communication links increases. <EOS>
