摘　　要：提出一种应用于多网关无线Mesh网络中的路由度量。首先建立多网关网络模型,获取网络拓扑信息并依此为网络节点分配不同的权值;然后通过网络拓扑信息及无线链路的衰落特性,推导网络中链路信号与干扰噪声比SINR的分布特性,进而计算链路的中断概率和中断速率;最后获取Mesh路由器节点缓存包数量,并计算网关节点容量占比,针对客户端业务和Internet业务设计具有保序性的ILR(Interfere and Load aware Routing)路由度量,网络依据路由度量为客户端业务和Internet业务选路。ILR路由度量考虑了网络干扰因素和负载分布信息,能够有效降低网络干扰,达到网络负载均衡、提高网络吞吐量的目的。A routing metric applied to multi-gateway wireless Mesh networks is proposed.This metric first establishes a multi-gateway network model,obtains network topology information and assigns different weights to network nodes accordingly.Then,the distribution characteristics of the link SINR are derived through the network topology information and the fading characteristics of the wireless link to calculate the outage probability and interrupt rate of the link.Finally,this metric obtains the number of Mesh router node cache packets,and calculates the gateway capacity,designs order-aware interfere and load aware routing metrics for client and Internet business.When there are client business and Internet business requests,this metric provides route through routing metric based on routing protocols for different business.This paper considers network interference factors and load distribution factors,can effectively reduce network interference,achieve network load balancing,and improve network throughput.
