摘要：
利用现有短波/微波电台或其他通信设备的数据传输能力,研制构建无线电战术互联网所需的互联网控制器和战术多网网关,从而使各类无线终端组成无中心的自组织网络,并通过TCP/IP协议与外部网络互连互通。采用VxWorks系统作为开发平台,经过系统裁剪和软件编码,将软硬件嵌入到网络核心设备中,运用无线仿真器进行辅助开发和性能测试。室内仿真和野外试验表明:组建的无线电战术接入网能够实现网络异构、路由自动选择等功能;在3~4节点的任意拓扑环境下,网络时延不超过30 s,并成功地接入有线网,能较好地提供各项数据传输业务。

Abstract: Based on the data transmission capacity of the existing shortwave / microwave radio or other communication equipment, an internet controller and a tactical multi-network gateway were developed to build a radio tactical access internet, enabling wireless terminals to form a self-organizing network and to interconnect with the external network through the TCP/IP protocol. Hardware and software, after being cut and programmed, were embedded to the core equipment in the network through VxWorks, a development platform. Indoor simulation and outfield tests show that the radio tactical access network is heterogeneous, can automatically select routes, and shortens network delay to no more than 30 seconds under any topology with three or four nodes, having been accessed to the wired network to provide various data transmission services.
