摘要

新兴的无线应用使得频谱短缺的问题不可避免。为了解决这一问题，提出了认知无线电网络。认知无线电是一种智能自适应设备，能够智能地感知频谱并发现频谱漏洞。本文提出了一种基于令牌的认知无线网状网络MAC协议。该协议包括传感、控制通道操作和数据通道操作三个阶段。在NS2中对所提出的MAC协议进行了仿真，并用不同信道数下的网络吞吐量对仿真结果进行了分析。仿真结果表明，所提出的MAC协议优于现有的MAC协议。

TMAC — Token based MAC protocol for cognitive radio wireless mesh network

Emerging wireless applications has made the issue of spectrum scarcity inevitable. To resolve this issue, cognitive radio networks are proposed. Cognitive Radios are intelligent adaptable devices which intelligently sense the spectrum and find out spectrum holes. In this paper, a Token based MAC protocol is proposed for cognitive radio wireless mesh networks. This protocol consists of three phases namely sensing, control channel operation, and data channel operation. The proposed MAC protocol is simulated in NS2 and the simulation results are analyzed using network throughput under various number of channels. The simulation results indicate that the proposed MAC protocol outperforms the existing protocols.
