A channel assignment algorithm for multi-radio multi-channel in wireless mesh networks

Abstract

Wireless mesh networks (WMN) are receiving increasing development, which configuration multi-radio multi-channel nodes to improve channel resources utilization in the network topology architecture and achieve increasing efficient on the network throughput. The main goal of channel assignment algorithms in multi-radio multi-channel wireless mesh networks is to minimize the overall interference and improve the aggregate network capacity while assuring the maintainment in the connectivity of the network. How to distribute the channel for each node to ratio interface in order to avoid the ripple effect and enhance network robustness while taking into account load balance and other performance indicators with the network medium. The article propose the channel assignment algorithm for multi-radio multi-channel wireless mesh networks based on the traffic flow of the link, which equitably distribute equalization for the business flow between nodes so that the distribution through the link on the flow of equal. The channel assignment improve network capacity by setting the value to reduce interference with the network overall interference.
