Problems solved by technology

[0006] In the above-mentioned improved WMN, a wireless transceiver of a node can only communicate with the only node among many other nodes. If a node needs to establish communication links with multiple neighbor nodes, it needs to be equipped with Corresponding number of wireless transceivers, resulting in higher equipment cost

Embodiment 1

[0039] Such as image 3 As shown, the wireless network planning method provided in this embodiment includes:

[0040] 301. Obtain location information of all nodes in the wireless network and service load information on each link.

[0041] In this embodiment, the location information of all nodes in the wireless network and the service load information on each link may be actively reported by each node, or may be issued by a command from the core network side to request each node to feed back its location information and the service load information on each link, and then obtained by statistics on the core network side;

[0042] Wherein, the service load information on each link refers to service load information on all links in the current wireless network.

[0043] 302. Determine an antenna direction of each wireless transceiver on the node according to the location information of the node and the service load information, and allocate a channel to each wireless transceive...

Embodiment 2

[0049] Such as Figure 5 As shown, the wireless network planning method provided in this embodiment specifically includes the following steps:

[0050] 501. Acquire location information of all nodes in a wireless network and service load information on each link.

[0051] In this embodiment, the location information of all nodes in the wireless network and the service load information on each link may be actively reported by each node, or may be issued by a command from the core network side to request each node to feed back relevant information, Then it is obtained by performing statistics on the core network side.

[0052] 502. Construct a routing tree with a gateway node in the wireless network as a root node according to the location information of the node and the service load information.

[0053] The goal of constructing the routing tree is to make the total service load of each routing tree achieve load balance, that is, the difference between the total service load ...

Embodiment 3

[0096] Such as Figure 12 As shown, the device for wireless network planning provided by this embodiment includes an acquisition unit 121 and a determination unit 122; specifically,

[0097] First, the obtaining unit 121 obtains the location information of all nodes in the wireless network and the traffic load information on each link; then, the determining unit 122 determines the An antenna direction of each wireless transceiver, and assign a channel to each wireless transceiver.

[0098] In this embodiment, the determination unit 122 further includes: a construction module 122a, a determination module 122b and an adjustment module 122c; wherein,

[0099] The construction module 122a is configured to construct a routing tree with the gateway node in the wireless network as the root node according to the location information of the node and the service load information; specifically, the construction module 122a sequentially selects a node to join at least one existing In so...

Abstract

The embodiment of the invention discloses a method and a device for planning a wireless network, relating to the field of wireless communication and being used for reducing network signal interference between links in WMN on the basis of not increasing cost. The wireless network planning method provided by the embodiment of the invention comprises the steps of acquiring positional information of all nodes in a wireless network and business loading information on each link; and according to the positional information of the nodes and the business loading information, determining antenna direction of each wireless transceiver on each node, and allocating channels for each wireless transceiver. The method and the device provided by the embodiment of the invention are applied to a wireless mesh network.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a wireless network planning method and device. Background technique [0002] Wireless mesh network (Wireless Mesh Network, WMN) is currently an effective technology to solve the "last mile" broadband access. The nodes in the WMN form a backbone network through wireless connections, some of which are connected to the Internet (Internet) in a wired manner, and are called mesh gateway nodes (generally referred to as gateway nodes); other nodes are ordinary nodes, which can be directly called mesh node. End users can access any mesh node, and then access the Internet through the WMN. [0003] Due to the influence of wireless signal interference, the end-to-end throughput in WMN is usually low; especially when the hop count (hop count) between the mesh node and the gateway node is large, this problem is more serious. [0004] In the prior art, there are many improvemen...
