Abstract

PURPOSE:To prevent a station which is low in priority order from being kept waiting for an extremely long time for transmission, by providing a counting means which counts the frequency of giving the priority to a host station transmitting when its own station wants to transmit and a priority order raising means which changes the priority order of its own station to a high order when the frequency exceeds a prescribed value. CONSTITUTION:At least a counting means which counts the frequency of giving the priority to the host station transmitting when its own station wants to transmit and a priority order raising means which changes the priority order of its own station to a high order when the counted frequency exceeds a prescribed value, are provided at one station. Therefore, when the number of times of its own station of being kept waiting for transmission due to the host station exceeds the prescribed value, the priority order of its own station is advanced. Therefore, the probability of being set to the transmittable state of its own station is improved and the station can transmit before its waiting time becomes extremely long.
