Problems solved by technology

[0005] Due to the unique flexibility of the wireless mesh network and the characteristics of the ad hoc network, there are difficulties in operation and management. Compared with the traditional star network, the wireless mesh network is a distributed network without a central point , and the wireless access points in the wireless mesh network are connected to each other by wireless means, which is a loose connection relationship. In addition, the customer site generally has mobility, which leads to the traffic carried by the backbone node with the Time changes, which increases the difficulty of balancing service loads and optimizing network resource allocation in wireless mesh networks

Embodiment 1

[0030] see figure 2 As shown, it is a schematic flow chart of Embodiment 1 of the method of the present invention. In this embodiment, it is mainly aimed at comparing the signal strength of each adjacent MAP with the signal strength of the MAP when a certain MAP is in a busy state. To determine whether to switch the MAP accessed by the access station for illustration.

[0031] Such as figure 2 As shown, in the present embodiment, the method of the present invention mainly includes steps:

[0032] Step S101: Detect and judge whether the number of access stations connected to the current MAP is less than the first preset maximum value, and whether the number of stable stations connected to the current MAP is smaller than the first preset stable value. If any one of the judgment results is no, Then it is determined that the current MAP is in a saturated state, and enters step S102; wherein, the first preset maximum value is the maximum value of the number of stations that the...

Embodiment 2

[0051] see image 3 As shown, it is a schematic flow chart of Embodiment 2 of the method of the present invention. In this embodiment, the main difference from Embodiment 1 above is that in this embodiment, it is judged whether the working power of each adjacent MAP satisfies the requirements of the access station. link quality requirements to illustrate.

[0052] Such as image 3 As shown, in this embodiment, the method of the present invention specifically includes steps:

[0053] Step S201: Detect and judge whether the number of access stations connected to the current MAP is less than the first preset maximum value, whether the number of stable stations connected to the current MAP is smaller than the first preset stable value, if any one of the judgment results is no, Then it is determined that the current MAP is in a saturated state, and enters step S202;

[0054] Step S202: the current MAP sends switching request information, and enters step S203;

[0055] Step S203...

Embodiment 3

[0069] see Figure 4 As shown, it is a schematic flow chart of Embodiment 3 of the method of the present invention. In this embodiment, the difference from Embodiment 1 above is that when a certain MAP is in a busy state, the feature sent by each MAP The signal strength of the signal is compared, and whether the working power of each adjacent MAP meets the link quality requirement of the access node is used to judge whether to perform handover.

[0070] Such as Figure 4 As shown, in the present embodiment, the inventive method mainly comprises steps:

[0071] Step S301: Detect and judge whether the number of access stations connected to the current MAP is less than the first preset maximum value, and whether the number of stable stations connected to the current MAP is smaller than the first preset stable value. If any one of the judgment results is no, Then it is determined that the current MAP is in a saturated state, and enters step S302;

[0072] Step S302: the current...

Abstract

The invention discloses a method for equalizing traffic load in a wireless mesh network (WMN). When the number of mesh access points (MAP) accessing a mesh point (MP) is not less than a first preset maximum value and the number of stable MAP accessing the MP is not less than a first preset stable value (i.e. the MP is in the saturation state of the first preset maximum value and the saturation state of the first preset stable value), the MP sends a switch request signal, an adjacent MP, which locates in the coverage area of the MP and has the number of MAP less than a second preset maximum value and the number of stable MAP less than a second preset stable value, receives the switch request signal, and when the switch requirements are judged to be satisfied in accordance with a preset judgment manner, the MAP accessing in the MP is switched to the adjacent MP which satisfies the switching requirements, so that the adjacent MP can share the traffic load of the MP which is in the saturation state, thereby effectively improving the entire traffic handling speed of the system and realizing equalization of traffic load in the WMN and optimizing allocation of network resources.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for balancing service load in a wireless mesh network. Background technique [0002] In the existing mobile communication network, it is usually necessary to establish corresponding network facilities such as base stations in advance, and the base stations implement central management to realize wireless communication. , floods, earthquakes, volcanoes and other disasters will no longer be applicable. In order to meet such needs, a new mobile communication network is designed and produced, which is called mobile Ad hoc network, also known as multi-hop network, wireless Fixed facility network, self-organizing network, it is a multi-hop, temporary, centerless network, neither fixed network structure, nor dedicated fixed base station or router as the management center of the network, all nodes in the network They can move freely in space, each node is equival...
