摘要
随着现代战争步入高科技时代,对军用机动通讯网的抗毁性、抗干扰性,
    以及机动灵活性提出越来越高的要求。80年代初期,Baker等人提出了短波自
    组织的组网原理及技术。利用该技术将能够保证网络在高度机动的情况下具有
    网络重组能力和高的服务质量。
     然而,采用该自组织网络技术的短波跳频通信网是由传统的跳频电台所构
    成的。其缺点在于:虽然该网络可以在多个频段互不干扰地进行周期性的分布
    式组网并进行通信,但通信进程只能在各自的频段上封闭地进行,而不能在各
    个频段之间进行跳转,这就限制了网络抗毁性能的进一步提高,不利于更好地
    进行网络的流量控制和拥塞控制。
     随着近年来软件无线电技术的迅速发展,一种新的战术“多频段多工作模
    式无线电台(MBMMR)”技术得以广泛应用。MBMMR电台是一种软件能配
    置的单一无线台。它把不同频段的电台有机综合进一部MBMMR电台之中,
    使之在功能上和使用时具有更大的灵活性,从而使通信进程能在不同频段之间
    进行跳转。
     本文借鉴了主动网的一些新思路,在网络分群组网算法的基础上,针对基
    于多频段多工作模式无线电台(MBMMR)网络的组网方法进行了研究。根据
    这一思想,本文采用BONeS Designer建立系统仿真模型。在此基础上,对本系
    统进行了仿真,收集了本系统在时延、网络吞吐量和分组丢失率等方面的统计
    特性,并进行了系统的性能分析。
     本文由五章组成。第一章对短波自组织组网技术的发展及其设计原则进行
    了简述;第二章对基于网络分群的组网算法和MBMMR电台的构造作了一个
    总体介绍;第三章介绍采用BONeS Designer设计的仿真系统模型框架结构、系
    统工作流程、系统仿真参数、系统数据结构等;第四章给出仿真系统的部分仿
    真结果并进行了分析;第五章则对全文的工作进行总结,指出存在的不足以及
    今后改进的方向。
While modern war came into the em of high technology, stricter requirements
     have been put ford to the properties of tactic mobile network, such as
     anti-demolition, anti-jam and mobilization. In 1980's, Mr. Baker raised the principles
     and technologies of self-organization of short-wave network. Using this technology,
     the ability of network reorganization and high quality of service in network can be
     guaranteed under the condition of high mobilization.
    
     However, the short-wave fiequency-hopping communication network adopting
     this technology is made up of traditional radios. The shortcoming of this network is
     that although it can organize network periodically and communicate simultaneously
     on different frequencies without any interference, the process of communication must
     strictly proceed in respective frequency without any change. This will limit the
     improvement of the ability of network anti-demolition, and could not conduct the flow
     control and congestion control of network better.
    
     Recently, with the rapid growth of soft radio, a new technology of Multi-band
     Multi-mode R.adio(MBMMR) has been applied widely. MBMMR is a single radio
     which can be deployed by software. It synthesizes the radios on different frequency
     into a single MBMMR, and makes it more flexible in capability and use, which means
     the process of communication can switch easily among different frequencies.
    
     This article absorbs some new thoughts of active network, and studies a method
     of Network Self-organization Based on Multi-Band Multi-Mode Radio using the
     improved algorithm of cluster linkage. Based on this method, We use Block Oriented
     Network Simulator (BONeS) to build simulation module. Through the simulation, we
     collect the datum in message and packet delay, network throughput, and packet loss
     rate, and analyze capabilities of the network based on them.
    
     This article consists of five chapters. Firstly, in chapter 1, we briefly describe the
     development and design principles of self-organization of short-wave network. In
     chapter 2, we introduce the improved algorithm of cluster linkage and the architecture
    
    
    
     of MBMMR. In chapter 3, we introduce this network simulation model built on
     BONeS Designer, including the system framework, execution process, system
     simulation parameters, data stnictures. Chapter 4 presents partial simulations results of
     this system, and analyzes them. In chapter 5, related conclusions in our study are
     stressed, and the deficiencies of this system and the way to modify them are described.
