ABSTRACT:
In a multi-radio mesh network system supporting at least two different wireless communication standards and a method of controlling the same, a wireless access switching module determines whether user data en-queued in the queue of a first wireless link and retained on standby cannot be transmitted. The wireless access switching module switches the user data, en-queued in the queue of the first wireless link and retained on standby, to an available second wireless link. The wireless access switching module changes a frame structure according to different wireless access techniques. When access is possible through the second wireless link, a forwarder searches for a local neighbor directly connected to a transmitting node and a receiving node, and forwards the user data. According to the invention, and in contrast to conventional techniques, available multi-wireless resources can be used more efficiently, flexibly and optimally up to the last moment, thereby reducing re-transmission and packet drop. Thus, each hop supports fast data forwarding so as to improve network performance.
