Abstract
According to one embodiment of the present invention, a multi-hop network system includes: a transmission node; a reception node; a router node; and a flow control node connected to all nodes within the multi-hop network system. The flow control node periodically receives flow monitoring information from at least one transmission node and evaluates whether the distributed state of the bandwidth of a network is fair. At this time, the flow control node sets a queue length threshold as transmission rate control information for fairly distributing the bandwidth of the network and transmits the set queue length threshold to at least one transmission node when unfairness has been detected. The transmission node sets the queue length threshold as a reference point for adjusting the transmission rate and performs the packet and/or link scheduling.
