Abstract:
1. A communication node that performs ad hoc communication in accordance with a time division multiple access scheme by occupying at least one time slot in one frame formed of a plurality of time slots and transmitting a data block to one or a plurality of other nodes via the occupied at least one time slot through broadcasting, the communication node comprising: a determination unit that determines, from among the plurality of time slots, an occupation time slot to be occupied by an own node in a transmission target frame used for transmitting the data block, based on occupation state data indicating an occupied/unoccupied state of each of the plurality of time slots, which the own node possesses at a time point before the transmission target frame; a data block generating unit that generates the data block storing, in a control field, control data containing new occupation state data obtained by updating the occupation state data based on an occupation state of the occupation time slot determined by the determination unit, the data block being to be transmitted by the own node through the broadcasting; and a transmission unit that transmits the data block generated by the data block generating unit through the broadcasting via the occupation time slot determined by the determination unit.
