【摘要】：由于日益增加的对电磁频谱资源的需求,世界范围内对频谱使用的竞争日趋激烈,而频谱却是不可再生的宝贵资源,为了更加合理的利用频谱资源,为了更加有利于相关部门对频谱资源的管理和分配,本文主要讨论了基于无线传感器网络电磁频谱信息监测的网络传输协议的设计与实现,以期对空间频谱信息能够有实时的了解和掌控。文中首先给出研究背景,说明了本系统实现的意义,旨在实现一个对频谱进行实时监测的系统,并能够对空间中的频谱信息进行检测、识别以及信号源定位等功能。接着简要介绍无线传感器网络、频谱监测等几个重要的概念之后,给出了国内外当前的研究现状。然后讨论了本系统所使用的三层两级网络架构,即基于任务管理中心、网关节点和感知节点三层网络节点,描述了各个网络节点所处的网络角色以及用途,描述了该网络架构的优点,网络节点的硬件构成,简单介绍了网络编程实现的原理,并分别给出了该两级网络连接实现的原理。本文详细阐述了基于TCP/IP协议集的模型,介绍了本系统在该模型的应用中,物理层链路层使用已经十分成熟的WIFI,WCDMA,TD-SCDMA等协议,在传输层网络层使用TCP/IP协议集中的各协议,并重点讨论了根据业务需求,从实际应用出发的应用层的协议,包括网络管理部分和具体业务方面的协议。在文章的最后,提出了由于信道、网络环境、业务数据量大等客观原因的存在,频谱显示的效果受到很大影响,在分析系统各个环节所带来的影响之后,对该原因进行剖析,并设计校准机制、流量控制机制,解决了通信信道带来的系统显示电平缺陷的问题,并大幅度减少在不稳定网络条件下的网络延迟。
[Abstract]:Because of the increasing demand for the electromagnetic spectrum resources, the competition for the use of the spectrum is becoming increasingly fierce in the world, but the spectrum is a valuable non-renewable resource, in order to make more rational use of the spectrum resources, In order to be more conducive to the management and allocation of spectrum resources, this paper mainly discusses the design and implementation of network transmission protocol based on electromagnetic spectrum information monitoring in wireless sensor networks. In order to have a real-time understanding and control of spatial spectrum information. In this paper, the research background is first given, and the significance of the system is explained. The purpose of this system is to realize a real-time monitoring system for spectrum, and it can detect, identify and locate the spectrum information in space. Then several important concepts such as wireless sensor network and spectrum monitoring are briefly introduced, and the current research situation at home and abroad is given. Then it discusses the three-layer and two-level network architecture, which is based on task management center, gateway node and perceptual node, and describes the network roles and uses of each network node. This paper describes the advantages of the network architecture, the hardware structure of the network node, briefly introduces the principle of network programming, and gives the realization principle of the two-stage network connection. In this paper, the model based on TCP/IP protocol set is described in detail. In the application of this model, the physical layer link layer uses WIFI,WCDMA,TD-SCDMA protocol, which is very mature. TCP/IP protocols are used in the transport layer network layer, and the application layer protocols based on the business requirements are discussed, including the network management part and the specific service protocols. At the end of the paper, it is put forward that the effect of spectrum display is greatly affected by the existence of the objective reasons, such as channel, network environment, large amount of traffic data, etc. After analyzing the influence of every link of the system, the paper analyzes the reason. The calibration mechanism and flow control mechanism are designed to solve the problem of system display level defect caused by communication channel, and the network delay under unstable network condition is greatly reduced.
