Abstract:
There is provided a wireless communication device including a communication section which receives, from an information distribution device that distributes distribution information or another wireless communication device that has received the distribution information, the distribution information using ad hoc wireless communication, a position information acquisition section which acquires position information indicating a current position, a movement amount calculation section which calculates a movement amount from the information distribution device based on a change in the position information acquired by the position information acquisition section, and a distribution information management section which manages availability of the distribution information based on the movement amount and a predetermined limited area-radius that defines a limited area in which the distribution information is distributed.
