Service load balancing method for wireless mesh network

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...

AI Technical Summary

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
