    • A new media access control (MAC) protocol for cognitive wireless networks is described. The new MAC protocol allows each of multiple nodes, such as cell phones and computers with wireless, to determine utilization of a communication spectrum, such as the television broadcast band. The nodes collaborate to achieve a combined view of spectrum utilization in their local vicinity, in which scheduled users and empty time segments are mapped across a wide range of frequencies. Nodes negotiate with each other to reserve idle segments of the spectrum for packet exchange on negotiated frequencies. Control packet structure allows nodes to become prescient of the local spectrum utilization during handshaking. A cognitive device operating under the new MAC has a first radio that both scans the spectrum and monitors a control channel; and a second reconfigurable radio with adjustable parameters, including frequency and bandwidth, for packet transmission.
    • 描述了用于认知无线网络的新的媒体接入控制(MAC)协议。 新的MAC协议允许诸如蜂窝电话和具有无线的计算机的多个节点中的每一个确定诸如电视广播频带之类的通信频谱的利用。 节点协作实现其本地附近的频谱利用的组合视图,其中调度的用户和空时间段在广泛的频率范围内被映射。 节点相互协商以在协商的频率上保留用于分组交换的频谱的空闲段。 控制分组结构允许节点在握手期间变得预先考虑本地频谱利用。 在新MAC下操作的认知设备具有扫描频谱并监视控制信道的第一无线电; 以及用于分组传输的具有可调参数(包括频率和带宽)的第二可重新配置的无线电。
