In order to improve serious signal interference and energy consumption of wire mesh backbone network due to omni-directional antenna communication mechanism, a topology control optimization algorithm in wireless mesh backbone networks based on directional antenna is proposed. At first, this algorithm used Delaunay graph model to quickly find gateway node by position information of network nodes. Then, in view of the relationship between network transmission distance and the node degrees, it optimizes the network topology structure and lines. In order to improve the transmission rate of wireless mesh network and solve new interference and energy loss problem after adjusting Delaunay graph to achieve a gateway deployment of wireless mesh network using directional antenna, the algorithm reduces wireless links that the transmission distance is too long and energy consumption is higher, and defines the upper limit of the number of directional antenna on routing nodes. The simulation results show that this algorithm can minimize the number of gateway and the shorten network transmission distance from route node to gateway node. This algorithm can effectively decrease the deployment cost and interference by using less antennas and promote the network performance at the same time.
