摘　　要：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和评价。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。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 procotols, the performance of this protocol is improved by using the mechanism of centralized control, distributed sensing and point to point communication. The stability and complexity of the system are taken into accout.
