Abstract: The present invention relates to a system and method for selecting a link and measuring link quality in a multi-radio wireless ad-hoc network environment. In a data transmission environment through a terminal in the multi-radio wireless ad-hoc network environment, provided is the system for selecting the link and measuring the link quality which includes: a first predicting unit which predicts an available bandwidth of a channel by using an amount of used channels calculated by a transmission node and a reception node in a media access control (MAC) layer; a second predicting unit which predicts the reduction amount of the available bandwidth due to a hidden node; a quality measuring unit which measures the link quality between the transmission node and the reception node by using the available bandwidth and the reduction amount of the available bandwidth; and a link selecting unit which selects the link with high quality among the links whose quality is measured.
