河北联合大学轻工学院QINGGONG COLLEGE, HEBEI UNITED UNIVERSITY毕业设计说明书111 方程段 1 部分 1论文题目：小型认知无线网络通信协议的制定与设计 2013 年 05 月 30 日摘 要认知无线电网络具有动态、灵活、智能地使用频谱资源，提高频谱利用率的特点，其网络结构和协议体系的设计是实现上述网络功能的关键。现有基于认知无线电技术的网络架构主要有美国的 CORVUS 系统，基于 IEEE 802.22 的无线局域网(WRAN)和支持多信道多接口的无线 Mesh 网络；协议体系有CORVUS 协议体系，军用的 XG 系统协议及 WRAN 协议等。提出了一种小型认知无线网络的频谱协同感知方法，并在此基础上设计了一种小型认知无线网络的通信协议。通过协议程序复杂度的角度切入，对该协议进行了分析。同其他典型协议相比较， 该协议通过采用集中式控制、分布式感知、点对点通信的机制，尽可能地做到了扬长避短，使系统的整体稳定性和复杂度得到了兼顾。关键词 认知无线电；网络架构；网络协议；认知无线网络；协同感知；通信协议；程序复杂度 AbstractCognitive radio networks have the abilities of utilizing spectrum dynamically， agilely and intelligently ， and improving the efficiency of spectrum usage. Consequently ， both the protocol and architectural designs for cognitive radio networks is very crucial. The network architectures in existing systems included contents are CORVUS system introduced in America ， Wireless Regional Area Network (WRAN) based on IEEE 802.22 as well as the wireless Mesh network supporting multi-channel and multi-interface ； related network protocols are of CORVUS system， the XG system for military applications， and WRAN.A cooperative spectrum sensing method of small -scale cognitive wireless network is proposed. On this basis ， a communication protocol of small -scale cognitive wireless network is designed. Starting from the program complexity， this paper analyzes and evaluates the communication protocol. Compared with other typical protocols ， the performance of this ...
