摘要：
An optimal resource allocation strategy for OFDMA multi-hop wireless networks is disclosed. The system allocates one or more resources in a multi-hop network by solving one or more higher-layer sub-problem; solving one or more physical layer and media access control (PHY/MAC) layer sub-problems per tone per time slot with one of cooperative relaying of radio signals or spatial reusing of radio spectrum; updating prices; and allocating radio resources based on the PHY/MAC layer sub-problems.
