Wireless communication device, information distribution system, program

An information distribution system comprising:

• an information distribution device which distributes distribution information;
• and
• a wireless communication device which receives, from the information distribution device or another wireless communication device that has received the distribution information, the distribution information using ad hoc wireless communication,
• wherein the wireless communication device includes
• a communication section which receives the distribution information,
• 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.
