近年来，无线网状网络已经吸引了许多用户，以通过经由无线连接将基站（网状节点）彼此连接来实现具有灵活配置和低成本特性的广域无线环境。当无线网状网络被用作因特网接入的基础设施时，来自移动的节点的所有网络业务通过直接连接到有线网络的网关节点。因此，我们需要通过部署多个网关节点来分配整个流量负载，并且每个网格节点应该根据其流量负载、处理能力和接入链路容量来选择网关节点来接入互联网。本文提出了一种将流量负载分配到网关节点上的路由方法。通过几个模拟，我们表明，所提出的方法可以均匀地分配网关节点上的流量负载，保持时间复杂度和抑制增加的路径长度最多15%相比，传统的最短路径路由。
Wireless mesh networks have been attracting many users in recent years to achieve a wide-area wireless environment with flexible-configuration and low-cost properties by connecting base stations (mesh nodes) with each other via wireless connections. When the wireless mesh networks are used as an infrastructure for Internet access, all network traffic from mobile nodes go through a gateway node which is directly connected to the wired network. Therefore, we need to distribute the entire traffic load by deploying multiple gateway nodes and each mesh node should select a gateway node to access the Internet according to its traffic load, processing power, and access link capacity. In this paper, we propose a routing method that distributes the traffic load on the gateway nodes. Through several simulations, we show that the proposed method can uniformly distribute the traffic load on gateway nodes, keeping the time complexity and suppressing an increase in the path length at most 15% compared to the conventional shortest path routing.
