[0023] DETAILED DESCRIPTION Specific terms are used to refer to specific elements. Those skilled in the art will understand that a manufacturer may use a different name for an element. In the present application, components are not distinguished by using different names for the components, but by different functions between the components. In the following detailed description and claims, the terms "comprising" and "comprising" are open definitions and should be understood as "including but not limited to". The term "coupled" should be understood as a direct or indirect electrical connection. Accordingly, if a device is electrically connected to another device, that connection may be a direct connection or an indirect connection through the use of other devices or connections.

[0024] Reference will now be made in detail to various embodiments according to the invention which will be illustrated in the accompanying drawings. While described in conjunction with these Exampl...

Abstract

The present invention provides a method of establishing a bidirectional route and a computer readable storage medium, wherein the method of establishing a bidirectional route includes the following steps: a first route request message is received by a first link with a second node in a wireless mesh network, the first routing request message includes information identifying the routing destinationnode as a final destination of the first routing request message; whether the first link is bidirectional is determined; when the first link is bidirectional, the second route request message is sentto the third node in the wireless mesh network through the second link, and the second route request message is not sent; the second route request message includes information identifying the routingdestination node as information of a final destination of the first routing request message. With the technical solution of the present invention, a bidirectional route between the routing originating node and the routing destination node can be established.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for establishing symmetric routing using bidirectional links in a wireless mesh network. Background technique [0002] A wireless mesh network is a collection of wireless nodes that can communicate with each other through a direct link between two nodes and / or through a route between the two nodes that includes a number of relay nodes (hops). A wireless mesh network is a form of wireless ad hoc (ad hoc) network. Ad Hoc On-Demand Distance Vector (AODV) routing (RFC 3561) is a routing protocol for ad hoc networks including wireless mesh networks. [0003] As described in RFC 3561, the message types defined by AODV include routing request messages and routing reply messages. The source node uses the route request message to find the route to the destination node. A Route Reply message is sent from the destination node to the source node to complete the route discov...
