摘　　要：在使用定向天线部署的无线Mesh网络中,为了保证用户的接入范围,在一个AP接入点必须配置多条定向天线,定向天线的数目增加会导致整个网络部署成本的增加以及在AP节点处造成天线自身的干扰。针对上述问题,提出一种基于用户QoS分析的部署优化算法,在保证用户QoS需求的前提下,减少AP处配置的天线数,达到减少天线自身干扰和降低网络部署成本的目的。最后对提出的算法进行了实验仿真分析,证明了算法的可行性,能够在实际的网络部署中获得良好的优化效果。In order to ensure the range of the user＇ s access, an access point must be configured with multi-directional antennas in the wireless Mesh network with directional antenna. The number of antenna increase will lead to the deployment cost increase and cause itself -interference at the access point. In response to these problems, a deployment optimization algorithm based on user＇ s QoS analysis is pro- posed. The algorithm can reduce the number of antennas at access point under the premise that guarantee user＇ s QoS requirements,itself -interference and the cost of network deployment can be reduced. Finally, the feasibility and effectiveness of the algorithm are proved by experimental simulation and analysis. The algorithm can be used in the actual network deployment to obtain well optimization effect.
