Abstract
A relay transmission device can achieve high-quality transmission by suppressing congestion in an ad hoc network, even when a network environment changes or performance of a relay device to be communicated with changes. The relay transmission device includes: an optimization coefficient storage unit () that stores, for each cooperative relay device, a self-optimization coefficient for weighting an amount of data determined by a self-optimization flow control unit () and a total optimization coefficient for weighting an amount of data determined by a total optimization flow control unit (); and a balance adjustment unit () that compares, for each cooperative relay device, an influence of congestion caused by transmission bandwidth allocation contention on the relay transmission device and an influence of congestion caused by transmission bandwidth allocation contention on the cooperative relay device, and adjusts the self-optimization coefficient and the total optimization coefficient based on a result of the comparison.
