  • 基于ZIGBEE的嵌入式自动抄表系统的研究.rar

    近年来,近距离无线传输技术是发展最快、最引入注目的技术,而ZigBee恰恰是填补了低速率无线通信技术的空缺,与其他标准在应用上相得益彰。它专注于近距离传输,成本低、同时入门槛也低,虽然其出现较晚,但目前已经得到人们越来越多的关注,成为无线技术研究的一个新热点。 本文在详细分析了传统的抄表方式和无线抄表系统的发展状况以及相关的无线数据传输技术的基础上,提出了基于ZigBee技术的无线抄表系统的方案。论文在研究ZigBee组网技术的基础上,设计了基于ZigBee开发平台的无线嵌入式抄表系统,编写了相应的软件,完成了相应的调试和分析,并进行了系统的可靠性、实时性和安全性等问题分析。为了减少系统由于节点路由而造成的功耗损耗过大的问题,本文在组网应用过程中采用Tree+AODVjr的路由算法,从而保持系统能够保持较小功耗的情况下进行数据的多跳路由,同时以ARM S3C2410为核心实现了基站设计,实现小区电表数据的集中采集,并通过GPRS/GSM模块实现基站和抄表中心的数据传输和实时控制,在此基础上,对抄表系统软件也进行了相应的设计。 通过单点对单点、星形网络数据传输实验,取得了相应的实验数据,对于协议的特点、系统可靠性和功耗情况有了整体把握,为今后ZigBee技术的进一步研究和应用打下了坚实基础。 实验结果显示,本文提出的方案切实可行,并且采用ZigBee技术具有节约资源、操作方便、可靠性高而且易于管理等特点,基站和系统利用较为成熟的GPRS/GSM网络技术进行通讯,既满足了实时性要求,又降低了成本。

  • 入侵检测系统的网络包分类技术研究

    基于FPGA技术的网络入侵检测是未来的发展方向,而网络包头的分类是入侵检测系统的关键。 文章首先介绍了FPGA技术的基本原理以及其在信息安全方面的应用,接着介绍入侵检测系统以及FPGA技术在入侵检测系统中的应用。 分析了几种比较出名的网络包分类算法,包括软件分类方法、TCAM分类算法、BV算法、Tree Bitmap算法以及端口范围分类算法。 在此基础上,文章设计了一个基于FPGA技术的入侵检测系统包分类的基本框架图,实现框架图中的各个基本功能模块。在实现过程中,提出了一类结合三态内容可寻址内存(TCAM)和普通存储器(RAM)的网络包包头分类方案。我们将检测规则编号并位图化,使用RAM存储与包头结构相关的规则位图,通过TCAM上的数据匹配操作,快速关联待分析的网络数据包与入侵检测规则。文章还讨论了网包头分类方法的优化算法,将优化算法与未优化算法在速度和空间上进行比较。此外,还讨论了对Snort的规则库进行整理和规则化的问题。 最后,对所设计的包头分类匹配模块在Quartus II进行仿真评估,将实验结果与已有的一些分类算法进行了比较。结果说明,本设计在匹配速度和更新速度上有优势,但消耗了较多的存储空间.

    This scheme is initiated by Ziv and Lempel [1]. A slightly modified version is described by Storer and Szymanski [2]. An implementation using a binary tree is proposed by Bell [3]. The algorithm is quite simple: Keep a ring buffer, which initially contains "space" characters only. Read several letters from the file to the buffer. Then search the buffer for the longest string that matches the letters just read, and send its length and position in the buffer.
