摘　　要：无线Mesh网络因其易部署和抗毁性强等特点,可在军事信息系统中用于无线组网。为了缓解无线Mesh网络中的网络瓶颈问题,可引入内容分发技术,以提高基于内容订阅模式的军事信息系统的服务质量。针对军事信息系统,我们设计了立体化的军事情报信息中心-战术通信卫星-小型分布式地面站-作战单元网络结构模型。在此模型基础上,我们对军事信息系统中基于无线Mesh网络的内容分发问题进行了形式化定义,并结合无线Mesh网络的分布式特点,提出了分布式四阶段启发式算法。仿真实验的结果证明该算法较大地优化了无线Mesh网络中的平均时延、网络负载等网络性能参数。Due to the characters of easy-to-deploy and invulnerability,wireless mesh network could be applied for wireless networking in military information system. To mitigate the bottleneck problem in wireless mesh network and improve the quality of service in the subscription based military information system,we could introduce the technique of content delivery. Thus,we design the network model including intelligence information center,tactical communication satellite,distributed ground station and combat unit. Based on this,we formally define the problem and propose a four phase based heuristics in combination with the distributed character of WMN. The simulation results show that our proposed scheme greatly improve the performance of wireless mesh network in metrics,such as average delay,network load and so on.
