随着海洋勘探需求的不断增长,水下广域网面临着提高网络吞吐量的严峻挑战。为了应对这一挑战,本文提出将IBFD技术应用于UWAN。IBFD技术可以通过在相同频带上同时发送和接收来潜在地加倍链路容量,这最近已经被证明对于无线通信是可行的。在这篇文章中,新的MAC协议是专门提出的声学IBFD网络,以克服固有的问题,在水声通信,如长的数据包延迟,大的节点碰撞概率,和高功耗。数值结果表明,我们的建议可以有效地减轻这些影响,提高整体性能的UWAN。
Driven by the increasing demand on marine exploration, UWANs are confronted with the rigorous challenge of improving network throughput. To deal with this challenge, this article proposes to apply the IBFD technique to UWANs. The IBFD technique can potentially double link capacity by simultaneously transmitting and receiving on the same frequency band, which has been recently demonstrated to be feasible for wireless communications. In this article, novel MAC protocols are specifically proposed for the acoustic IBFD network to overcome the inherent issues in underwater acoustic communications, such as long packet delay, large node collision probability, and high power consumption. Numerical results verify that our proposals can effectively mitigate these effects and improve the overall performance of the UWANs.
