Problems solved by technology

However, they all have some disadvantages. For example, CEDAR has high requirements on the information processing ability of nodes, and the routing method of Qos is relatively complicated; although Qos-OLSR can provide users with minimum available bandwidth and maximum delay guarantee, it still cannot Solve the inherent defects of proactive routing

Embodiment Construction

[0035] The present invention will be further described below in conjunction with specific examples.

[0036] like figure 1 As shown in the figure, user 1 in the figure is attached to wireless router A, and requires 1M bandwidth for user 2 to initiate a service, and user 2 is attached to wireless router B. User 1 requests to establish two paths, then after the routes are created successfully, there are paths that meet the requirements via wireless router C and wireless router D as shown in the figure.

[0037] In a wireless network, bandwidth is a scarce resource. How to effectively plan resources in the routing establishment process to meet the user's business bandwidth requirements is an urgent problem to be solved by new routing protocols; in order to provide Qos guarantees, routing protocols must solve : Carry user QoS information when routing is established. During route discovery, nodes can provide accurate measurement of available resources through the physical layer. T...

Abstract

The invention relates to a Mesh routing method supporting Qos guarantee. The method includes a route discovery process, a route exploration and maintenance process, a periodical network node self-test process and an internal expansion process. Compared with the prior art, the invention provides an effective route establishment and maintenance method supporting Qos guarantee for a Mesh network, and the routing method can provide bandwidth-guaranteed routing for users, thus guaranteeing service quality.

Description

technical field [0001] The invention relates to a method for establishing a route according to user's bandwidth requirement for a wireless mesh network and updating the route according to the change of the wireless network, in particular to a mesh routing method supporting Qos guarantee. Background technique [0002] At present, there are mainly two types of routing protocols in wireless Mesh networks: proactive routing and reactive routing, proactive routing such as optimal link state routing protocol OLSR (RFC3626), topology distribution routing protocol based on reverse path forwarding TBRPF (RFC3684 ) etc.; reactive formulas such as Aodv (RFC3561), DSR (RFC4728), etc. However, the above-mentioned protocols do not provide users with Qos guarantees, but only provide an available path. As for the data transmission effect that this route can achieve, it is completely unpredictable. As a result, services with high network requirements such as video and voice cannot be applie...
