摘要： 在多网关的无线Mesh网络(WMN)中，网关选择影响了WMN的性能。从网关负载的角度进行考虑，提出负载均衡的网关选择策略。通过在Mesh管理帧中增加网关负载信息位，将网关的负载信息传递给需要做网关选择的节点。在网关选择时综合考虑网关Metrics和负载信息，并做出合适的选择。将该方法在NS2仿真软件中进行了仿真实验，并对结果进行分析。

Abstract: Gateway selection problem is brought in multi gateway Wireless Mesh Network(WMN). Gateway selection influences network performance in various aspects. This paper proposes a gateway selection strategy in a way of gateway load balancing. It tries to add information to 802.11s management frames in order to pass the gateway’s load information to the related nodes. When selecting gateway, gateway’s load and metrics are considered both. This paper also emulates the method in NS2 and analyses the result.

Key words: Wireless Mesh Network(WMN), gateway selection, 802.11s standard
