Abstract

The multi-channel MAC protocols have been proposed recently to improve the network capacity by accommodating more concurrent transmissions. In this paper, we propose a distributed multi-channel MAC protocol using reliable multiple channel reservation with only a single transceiver. Specifically, the control handshake information is reserved to be re-broadcasted over the control channel to address the multi-channel hidden terminal problem. Besides, by reserving multiple data transmission opportunities on the selected data channel, the control channel congestion is further relieved. Then we prove that the multi-channel hidden terminal problem can be addressed using reservation on the control channel, and analyze the effectiveness of the proposed protocol in the aspect of the average number of data channels simultaneously utilized. Extensive simulation results show that the proposed protocol is able to achieve nearly 2.5 times the saturation throughput of DCA protocol [15] when five-step channel reservation is adopted.

一个可靠的信道保留基于多通道MAC协议与一个单一的收发器

最近提出了多通道MAC协议，通过容纳更多的并发传输来提高网络容量。在本文中，我们提出了一个分布式多通道MAC协议，使用可靠的多通道保留，只有一个收发器。具体来说，控制握手信息保留在控制通道上重新广播，以解决多通道隐藏终端的问题。此外，通过在所选数据通道上保留多个数据传输机会，进一步缓解了控制通道的拥塞。在此基础上证明了在控制信道上预留可以解决多信道隐藏终端问题，并从同时使用的平均数据信道数方面分析了所提协议的有效性。大量的仿真结果表明，采用五步信道保留时，该协议的饱和吞吐量是DCA协议[15]的近2.5倍。
