一种基于北斗的混合式无线自组网系统设计

在林业、消防、治安反恐、军事等领域,任务单元之间灵活、可靠的动态自组网数据传递,是提高一体化指挥能力和快速响应能力的关键所在。传统的无线局域自组网技术易受距离、遮挡等条件限制,在大区域、有遮挡条件下的应用有一定局限性。文章基于北斗系统定位和短报文通信能力,结合无线局域自组网技术,利用北斗应用终端设备为骨干构建了分层编组逻辑网络,有效扩大了覆盖范围和增强了组网可靠性。不同参数的网络变化与修复过程的仿真表明,该系统能够实现动态环境中网络修复与重组,提供可靠通信保障,解决了多种场合下所需的精确、无间断一体化指挥要求。

Design on a hybrid wireless ad hoc network system based on Beidou

In the fields of forestry,fire fighting,public security,anti-terrorism and military affairs,flexible and reliable data transmission between task units in dynamic ad hoc networks is the key to improve integrated command capability and fast response capability.Traditional wireless local area ad hoc network technology is easily limited by distance,occlusion and other conditions,its application in large areas with occlusion has certain limitations.In this paper,based on Beidou system positioning and short message communication capabilities,combined with wireless local area ad hoc network technology,a hierarchical grouping logical network is constructed using BeiDou application terminal equipment as the system effectively enhancing the coverage and networking reliability.The simulation experiments results of network changes and process reparation with different parameters show that this system can realize network repair and reorganization in dynamic environment,provide reliable communication guarantee,and solve the requirements of precise and uninterrupted integrated command in various occasions.
