Although OFDMA is a candidate physical layer protocol for 802.16, there are few solutions for the wireless resource-allocating problem in OFDMA mesh network. In this paper, we study the current resource allocation methods in OFDM and OFDMA network, and introduce the architecture of OFDMA mesh network. We build a mathematic system model for the OFDMA mesh network, and propose a sophisticated ACO-based algorithm for wireless resource allocation. With our algorithm, we get acceptable solution, while fulfilling power and QoS constraints. Since our algorithm is easy to adapt to more realistic problems, it turns out to be a feasible method. The simulation result showed our algorithm is able to find a sub-optimal answer for resource allocation in OFDMA mesh network.
