摘要
Provided in the present invention is a wireless mesh network opportunistic routing algorithm based on Quality of Service assurance, relating to the technical field of wireless communication, each node in the network periodically exchanging information in order to acquire the real-time state of the network. When a node needs to forward service data, first selecting a forwarding candidate node range in a targeted manner on the basis of geographic location information. On the basis of the network state and Quality of Service requirements, selecting a suitable candidate next hop node set and implementing priority ranking of the candidate next hop node set, wherein the higher the priority, the more likely to be the next hop. If no candidate node successfully becomes the next hop, then temporarily caching the data, and re-issuing a routing request. The present invention incorporates the real-time state of network links into the process of selecting a candidate next hop node for forwarding data, taking Quality of Service requirements into full consideration, and implements priority ranking of the candidate next hop nodes, ensuring the reliability of data forwarding, and thereby effectively ensuring the Quality of Service requirements when forwarding data whilst improving the real-time utilisation efficiency of the network.
