摘　　要：传统的无线Mesh网络(WMN)路由协议利用路由管理帧携带的路由信息来维护路由。无线环境的不稳定性可能导致路由管理帧丢失,使路由协议无法及时获取正确的路由信息,从而降低网络性能。介绍了一种基于统计学原理的无线Mesh网络路由协议B.A.T.M.A.N.(Better Approach To Mobile Ad-hoc Networking)。该协议通过统计路由管理帧的投递成功率来选择最优路径,消除了路由管理帧丢失对路由协议的影响。通过与OLSR的测试对比表明,B.A.T.M.A.N.在无线Mesh网络中有更好的性能表现,更适用于移动网络。Traditional routing protocols for wireless mesh network（WMN） use the muting information carried by mana- gement frames to calculate,compare and choose route. However the necessary routing information is not available be- cause the management frames can be lost due to the instability of wireless environment, which degrades the performance of network. This paper introduced a new routing protocol named B. A. T. M. A. N. （Better Approach To Mobile Ad-hoc Networking） based on statistics. The loss of management frames makes sense because this protocol decides best paths according to the packets delivery rate of management frames. Experiment shows that B. A. T. M. A. N. outperforms OL- SR in wireless mesh network and achieves greater advantages in mobile network.
