The invention provides a resource distribution method of a multi-hop multi-frequency-point wireless mesh network. The method comprises: channel resources on all frequency points are divided into time-frequency resource blocks; the interference value of each node on each time-frequency resource block is calculated; for a node participating in a service flow, a constraint condition is set according to a QoS requirement of the service and a resource distribution strategy owned by the node is selected to carry out repeated gaming; when a repeated gaming termination condition is met, the repeated gaming is stopped; if the node resource distribution scheme obtained by the repeated gaming can improve the network throughput capacity, a total resource distribution scheme is updated and is broadcasted, and otherwise, resource distribution fails; and after all nodes receive a broadcast frame carrying the new distribution scheme information, service transmission is carried out based on the new resource distribution scheme. According to the invention, with the repeated gaming method, multi-frequency-point channel resources are distributed and reused, so that the network capacity and the bearable service load are improved effectively.
