Other AbstractThe invention discloses a traffic awareness based dynamic networking method, which is applied to an industrial wireless backhaul network based on a Mesh network technique. According to an available channel bank C, a link capacity bank {c(e)} (e belonging to E), a traffic bank {f(e)} (e belonging to E) and a global utility threshold Lambda 0 which are given, a channel c and a rate rm are manually allocated for a link in a network topological graph G(V,E); a manager node computes a current global utility function periodically; if the current global utility function meets the condition that Tu is greater than Lambda 0, the networking process is triggered, so that network reconfiguration is realized. The method adopts a centralized management mechanism, so that the operation load of a single node of the network is reduced, and networking information is sent to all nodes through the broadcast characteristic of the wireless Mesh network. Furthermore, in realization of channel dynamic reallocation, the method takes full consideration of the current state of the channel, thereby reducing network temporary interruption due to channel allocation switching, and improving the throughput and stability of the wireless Mesh backhaul network.
