Method for realizing routing of wireless mesh network and wireless mesh network node

Abstract

The invention discloses a method for realizing the routing of a wireless mesh network, which comprises the following steps: A. a source node sends a route request message to a surrounding intermediate node, wherein the route request message carries initial route criterion information which is provided by the source node and used for choosing routes; B. after receiving the route request message, the intermediate node updates the received route criterion information according to the network data of the intermediate node, and sends the route request message to the next node, wherein the route request message carries updated route criterion information; C. after receiving the route request message sent by the intermediate node, a destination node obtains the route criterion information of the route, and returns a route response message to the source node according to an original route, wherein the route response message carries the route criterion information of the route; and D. the source node chooses appropriate routes according to the types of services and the route criterion information of each route in the route response message returned by the surrounding intermediate node. The method for realizing the routing of the wireless mesh network and the wireless mesh network node of the invention are used for realizing service-based routing.

Description

technical field [0001] The invention relates to the field of wireless communication networks, in particular to a wireless mesh network routing implementation method and a wireless mesh network node. Background technique [0002] Wireless Mesh Network (WMN) is a multi-hop, self-organizing and self-healing broadband wireless network structure, and also a high-capacity, high-speed, low-power, low-cost distributed network. It solves the problem that traditional wireless local area networks (WLANs) cannot meet users' requirements for always-on services anytime, anywhere, and helps to cost-effectively extend the coverage of WLANs beyond hotspot areas, bringing real mobility and flexibility to users. [0003] At present, WLAN networks generally tend to adopt a centralized architecture, such as figure 1 As shown, the AC (Access Controller, wireless access controller) configures, controls and manages multiple APs (Access Point, wireless access control point), and the AP joins the WL...
