【摘要】：在无线Mesh网络中,绝大部分数据都是通过网关与外网进行交互,随着网络中数据传输量的增加,单网关很容易达到传输瓶颈,从而导致网络的整体性能下降.本文对802.11s中规定的混合无线Mesh路由协议HWMP(Hybrid Wireless Mesh Protocol)进行改进,提出了具有负载均衡功能的多网关路由协议LBM P_HWM P.通过在M esh管理帧中添加路径负载信息位,用于表示当前路径的节点拥塞情况,节点在选择网关传输数据的时候综合考虑链路质量与路径中节点的拥塞情况,从而均衡整个网络的负载,避免拥塞发生.仿真实验表明,LBMP_HWMP能够很好地保持整个网络的负载均衡,降低端到端的传输时延,提高网络的整体性能.
[Abstract]:In the wireless Mesh network, most of the data are interacted with the external network through the gateway. With the increase of data transmission in the network, the single gateway can easily achieve the bottleneck of transmission, resulting in the overall performance degradation of the network. In this paper, the mixed wireless Mesh road defined in 802.11s is changed by the protocol HWMP (Hybrid Wireless Mesh Protocol). In addition, the multi gateway routing protocol LBM P_HWM P. with load balancing function is proposed to express the node congestion in the current path by adding path load information bits in the M ESH management frame, and the node considers the link quality and the congestion in the path when the data is transmitted by the gateway, thus balancing the entire network. The simulation experiment shows that LBMP_HWMP can maintain the load balance of the whole network well, reduce the end to end transmission delay, and improve the overall performance of the network.
