Wireless mesh network (WMN)-based association and seamless handover method

Abstract

The invention discloses a wireless mesh network (WMN)-based association and seamless handover method. The method comprises the following steps that: an access network for accessing a client to Internet is arranged in the wireless mesh network; the access network comprises a gateway and more than two access points; the network parameters of the more than two access points are identical; when the client is accessed or mobile, the gateway appoints an access point with shortest data forwarding delay from the more than two access points as the current service access point of the client in real time; and the current service access point and the client perform data communication directly. The method has the advantages of high network throughput rate, short end-to-end delay, low packet loss rate and high network safety performance, and the like.

Description

Wireless Mesh Network Network Dominant Association and Seamless Handover Method technical field The invention relates to a mobility management method of a wireless mesh network, in particular to a network-led association and seamless switching method of a wireless mesh network. Background technique In a wireless mesh network (Mesh network), a wireless client must associate with a mesh network access point (AP) before it can access the network. When there are multiple access points within the communication range of the client computer, the client computer will select one of them for association. The currently commonly used wireless mesh network is based on the IEEE (Institute of Electrical and Electronics Engineers) 802.11 standard. In this standard, the association between the client and the access point is selected by the client based on the received signal strength (RSSI) of the access point, that is, the client chooses the access point with the strongest signal for as...

Problems solved by technology

However, if the client wants to understand the syntax and semantics of the information, it needs to modify the client's wireless network card driver or the IEEE802.11 standard, which makes these methods not practical, and the exposure of too much information also makes the network security vulnerable to threats
