Method and apparatus for mixed routing in wireless mesh network

Abstract

The present invention provides a routing management method of a wireless mesh network: a routing information of all MESH nodes websites subordinate in the wireless mesh network is maintained; a unicast routing request message transmitted by a source MESH node is received; a routing response message is transmitted by the source MESH node, the response message comprises a routing information arriving the destination website subordinate of a destination MESH node, with the aim that the source MESH node source website subordinate transmits messages to the destination MESH node destination website subordinate. The present invention establishes the routing between the MESH nodes in advance in network, the routing information of the STA is not needed to be maintained by a RA-OLSR, but is realized through the unicast routing request message of an HWMP, the complexity of a RA-OLSR is decreased, the broadcasting flooding process of the HWMP routing request is avoided, and the network protocol overhead is lightened.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a hybrid routing method and equipment in a wireless mesh network. Background technique [0002] A WLAN (Wireless Local Access Network, wireless local area network) provides a wireless connection service of a local area network. Because it can provide high-speed wireless data access, WLAN is one of the more popular technologies in the IT industry at present, and it is also a popular wireless access method. The WLAN generally adopts a centralized AC (Access Controller, wireless controller)-AP (Access Point, wireless access point) architecture. The AC provides centralized management of the WLAN network, and the AP establishes a link with the AC to join the WLAN network and provide wireless access services. [0003] The centralized WLAN architecture is clearly defined in the CAPWAP (Control and Provisioning of Wireless AccessPoints) protocol, which describes the divi...

Problems solved by technology

[0006] In the prior art, routes are obtained by broadcasting routing requests through the HWMP protocol or RA-OLSR (Radio Aware Optimize LinkStatus Route). For users who go online and offline frequently, the routing information will change frequently, causing heavy network load

In addition, although the RA-OLSR protocol can easily construct the routing between nodes in the MESH network, the mobility of STAs will lead to the synchronization of routing information in the entire network, which will greatly increase the burden of the RA-OLSR protocol, and in certain cases will cause the protocol to invalid
