IEEE802.11s-based multi-gateway wireless Mesh network realization method

Abstract

The invention discloses an IEEE802.11s-based multi-gateway wireless Mesh network realization method. A multi-gateway wireless Mesh network is realized based on IEEE802.11s. A method for selectively discarding BPDU frames and tagging and filtering broadcast frames is designed, and problems about interconnection with a distributed system caused by introduction of multiple gateways, such as spanning tree port congestion and broadcast storm, are solved. When a terminal sends data to an external network, a gateway with the smallest load is selected on the premise of meeting the QoS requirement of the service, so as to achieve the purpose of gateway load balancing. The load index is the number of bytes which are sent by a wired network card of a gateway node to the external network during the time interval between two times of gateway announcement sending, and the load index is added to an RANN frame and broadcasted. A multi-gateway wireless Mesh network and gateway load balancing are realized. A gateway with smaller load can be selected when a network node and the external network exchange data, thereby improving the performance of the entire network.

AI Technical Summary

Benefits of technology

This patented technology improves on existing methods for creating multiple gateways within an area called MultiWireless Network (MWN). It allows each node connected through different paths from one another while still being able to communicate properly with other devices outside it's own network. Additionally, this new solution simplifies the process of modifying or combining certain features like Time Division Multiple Access (TDMA) signals into more efficient ways than traditional wired connections. Overall, these technical improvements make up what we call a better way to connect things together wirelessly at once.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving wireless mesh networks' efficiency when handling varying amounts of data transmission over long distances without wasting valuable bandwidth or requiring excessive processing power at certain points along its route. This issue arises because it requires nodes with many connections that may also connect wirelessly into other areas outside their own area called “hop” zones where they cannot communicate properly.
