With the massive growth of wireless networks comes a bigger impact of collisions and interference, which has a negative effect on throughput and energy efficiency. To deal with this problem, we propose an in-band wireless collision and interference detection scheme based on full-duplex technology. To study its performance, we compare its throughput and energy efficiency with the performance of traditional half-duplex and symmetric in-band full-duplex transmissions. Our analysis considers a realistic protocol and overhead modeling, and a measurement-based self-interference model. Our results indicate that our proposed collision detection scheme can provide significant gains in terms of throughput and energy efficiency in large wireless networks. Moreover, when compared to half-duplex and symmetric full-duplex, our analysis shows that this scheme allows up to 45% more nodes in the network for the same energy consumption per bit. These results suggest that this could be an enabling technology towards efficient, dense wireless networks.

随着无线网络的迅猛发展，冲突和干扰带来了更大的影响，这对吞吐量和能效产生了负面影响。为了解决这个问题，我们提出了一种基于全双工技术的带内无线冲突和干扰检测方案。为了研究其性能，我们将其吞吐量和能效与传统的半双工和对称带内全双工传输的性能进行了比较。我们的分析考虑了现实的协议和开销模型，以及基于测量的自干扰模型。我们的结果表明，我们提出的冲突检测方案可以在大型无线网络的吞吐量和能效方面提供可观的收益。而且，与半双工和对称全双工相比，我们的分析表明，在相同的每比特能耗下，该方案最多可以使网络中的节点增加45％。这些结果表明，这可能是实现高效，密集无线网络的一项使能技术。
