Abstract: A communication device includes: a receiving unit that receives first peripheral device data, which relates to a movement state of a first peripheral device, and second peripheral device data, which relates to a movement state of a second peripheral device; an acquiring unit that acquires host device data which relates to a movement state of a host device; a control unit that calculates host device collision prediction time between the first peripheral device and the host device and other device collision prediction time between the first peripheral device and the second peripheral device, and shortens a transmission interval of the host device data when the host device collision prediction time is shorter than a predetermined value and the host device collision prediction time is shorter than the other device collision prediction time; and a transmission unit that transmits the host device data according to the transmission interval.
