摘要:

我们考虑认知媒体访问控制(MAC)协议的设计,该协议使得未授权(辅助)发射机-接收机对能够在一组授权信道的空闲时段上进行通信,即,的主要网络。目标是最大化数据吞吐量,同时保持次级用户之间的同步,并避免与授权(主)用户的干扰。没有关于主业务的统计信息被假定为对次用户先验可用。我们调查两个不同的感知场景。在第一种情况下,次发射机能够感测所有主信道,而在第二种情况下,次发射机仅感测一个信道。在这两种情况下,我们提出了MAC协议,有效地学习统计的主要交通在线。我们的仿真结果表明,建议的盲协议渐近实现的吞吐量时,获得的先验知识的主要流量统计。

英文摘要:

We consider the design of cognitive Medium Access Control (MAC) protocols enabling an unlicensed (secondary) transmitter-receiver pair to communicate over the idle periods of a set of licensed channels, i.e., the primary network. The objective is to maximize data throughput while maintaining the synchronization between secondary users and avoiding interference with licensed (primary) users. No statistical information about the primary traffic is assumed to be available a-priori to the secondary user. We investigate two distinct sensing scenarios. In the first, the secondary transmitter is capable of sensing all the primary channels, whereas it senses one channel only in the second scenario. In both cases, we propose MAC protocols that efficiently learn the statistics of the primary traffic online. Our simulation results demonstrate that the proposed blind protocols asymptotically achieve the throughput obtained when prior knowledge of primary traffic statistics is available.
