Disclosed are a communication mediation apparatus and a method for controlling the same for performing communication mediation while reducing a communication miss rate caused by collision of data. A performance of a moving object recognition system unavoidably varies with the number of moving objects to be recognized by a controller, and with a mediation parameter for use in a communication mediation algorithm. The apparatus/method dynamically varies a mediation parameter according to a difference in numbers of many moving objects, thus reducing a communication miss rate regardless of the difference (i.e., traffic volume variation) in numbers of the moving objects.
