1. A wireless communication device included in a multi-hop network in which data is relayed in multiple stages in time division communication, the wireless communication device comprising:
one or more hardware processors configured to function as:
a decision unit that decides an additional slot, based on identification information received from a child node that transmits data to the wireless communication device;
a communication processing unit that transmits and receives data using the additional slot and a basic slot assigned based on frame information in the time division communication; and
a control unit that controls a start and an end of a burst mode that uses both the basic slot and the additional slot by determining a predetermined parameter by using a threshold, wherein
the wireless communication device includes a normal mode that uses the basic slot and the burst mode, and
when the burst mode is started, the communication processing unit transmits start information of the burst mode to a parent node of the wireless communication device, and when reception of the start information by the parent node is confirmed, the communication processing unit transmits and receives data using both the basic slot and the additional slot.
