Abstract

Cognitive radio (CR) offers a new mechanism for flexible usage of radio spectrum. This paper presents a full-duplex multi-channel MAC protocol designed for CR enabled multi-hop networks. Each node is equipped with at least two transceivers, one for transmitting and another for receiving. A node selects an unused frequency band as its home channel (HCh) and tunes its receiver to its HCh. When a node j has a packet to transmit to its neighbor i, node j tunes its transmitter to the HCh of node i and sends the packet(s) to node i using CSMA/CA scheme of IEEE 802.11 DCF mode. The protocol has two flavors: (a) With a common control channel which requires 3 transceivers and (b) without the control channel. Simulation studies show that the proposed protocol outperforms IEEE 802.11 DCF mode by a factor of 20

多跳认知无线网络的全双工多通道MAC协议
认知无线电(CR)为无线电频谱的灵活利用提供了一种新的机制。本文提出了一种全双工多通道MAC协议,用于支持CR的多跳网络。每个节点配备至少两个收发器,一个用于发送,另一个用于接收。节点选择一个未使用的频带作为它的主信道(HCh),并将它的接收器调谐到它的HCh。当节点j有报文需要发送给邻居i时,节点j将发送器调至节点i的HCh,并使用IEEE 802.11 DCF模式的CSMA/CA方案将报文发送给节点i。该协议有两种形式:(a)有一个公共控制通道,需要3个收发器;(b)没有控制通道。仿真研究表明,该协议的性能比IEEE 802.11 DCF模式高出20倍
