Collaborative Research: NeTS-NBD: Optimal Channel-Aware Access Control for Multi-hop Wireless Networks

这个项目旨在开发一种形式化的方法来分析无线网络中的信道感知随机接入。这项工作的独特之处包括：开发模型，除其他参数外，将通道状态作为其公式的中心方面，并使用交叉工具来分析此类网络的性能。在这个项目中，模型和由此产生的解决方案的数学支柱是最优化和博弈论。在此过程中将出现的具体结果包括：合并了信道感知和捕获的模型，更好地理解了在随机接入中使用机会主义，最后，理解了在多天线随机接入中分配自由度的方法。底层物理介质对接入方案的性能的影响可能是相当大的，特别是在信道高度动态且受周围环境的大量变化影响的无线环境中。因此，对物理介质的简明表示与复杂的分析技术相结合来处理所产生的模型，对于利用随机接入中的信道感知所产生的收益是至关重要的。

This project aims at developing a formal methodology for analyzing channel-aware random access in wireless networks. The unique features of this effort include: the development of models that incorporate, amongst other parameters, channel state as a central aspect of their formulation, and the use of cross-cutting tools to analyze the performance of such networks. The mathematical backbone from which the model and resulting solutions arise in this project are optimization and game theory. The specific results that will emerge during the course of this effort include: models that merge channel awareness and capture, a better understanding of the use of opportunism in random access, and finally, an understanding of the ways in which degrees of freedom can be allocated in multiple-antenna random access.The impact of the underlying physical medium on the performance of access schemes can be considerable, particularly in wireless settings where the channel is highly dynamic and is impacted by myriad changes in the surrounding environment. Thus, a succinct representation of the physical medium combined with sophisticated analytical techniques to tackle the resulting models are essential to tap into the gains resulting from the use of channel-awareness in random access.
