摘　　要：无线信道在战术通信网络广泛使用,具有带宽窄、丢包率高和广播的特性。软件升级可修正设计的缺陷和程序错误,改进已有功能或者增加新的功能。通用的软件升级方法依赖IP数据通信。战术通信网络路由动荡频繁,IP数据通信不可靠,而通用的软件升级方法不能很好地用于战术通信网络。因此,采用泛洪算法作为基础,将泛洪算法与无线信道结合,提出了一种不依赖IP数据通信能够适应战术通信网络软件升级的方法。采用通用的泛洪算法在区域内传输升级报文,优化报文在无线信道的传输以大幅减少开销,并且保证了传输可靠性。最后,完成了该方法的实现和验证。Wireless channels,for its characteristics of narrow bandwidth,high packet-loss-rate and broadcast,are widely used in tactical communication networks.Software upgrade may fix design flaws and bugs,improve existing features,or add new features.The general software upgrade method relies on IP data communication.For the reason that the tactical communication network has frequent routing turbulence and unreliable IP data communication,general software upgrade methods couldn’t be well used in this tactical communication network.With flooding algorithm as the basis,and by combining the flooding algorithm with the wireless channel,a method that can adapt to the tactical communication network software upgrade without IP data communication is proposed.The general flooding algorithm is used to transmit upgrade packets in the area.The optimization of packets transmission on the wireless channel can greatly reduce overhead and ensure transmission reliability.Finally,the implementation and verification of the proposed method is done.
