【摘要】 恶劣环境下无线信号会出现时断时续的不稳定现象,导致传统的保持在线连接的通信方法不能正常工作。为此,提出了一种“信号-时间窗”分析指引下的基于FTP协议传送经混沌加密及压缩处理的XML文档的数据通信策略,给出了其在恶劣信道下成功应用的实例。系统投入运行半年多的实践结果表明,该通信策略能很好地解决恶劣环境下的数据通信问题,保证了通信的敏捷性、完整性、保密性和可靠性,在恶劣通信条件下或异构系统之间的数据通信领域具有相当的应用价值和参考意义。更多还原

【Abstract】 In adverse environments,wireless communication speed is slow and often breaks down.It causes the traditional keeping-in-connection communication methods do not work.To resolve this problem,a communication strategy is presented,which uses signal time window and FTP to transmit chaotic-encrypted and compressed XML document.The application example is also given,which has been put to use for more than half a year.The experiments and application results show that the proposed communication strategy does good work at bad communication conditions,and has the advantages of agility,completeness,security and stability,which can be widely applied in the data communication fields under bad communication conditions or between different systems.更多还原
