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.

本计画旨在发展一种分析无线网路中频道感知随机存取的正式方法。这项工作的独特之处包括：模型的开发，除其他参数外，将信道状态作为其制定的一个中心方面，并使用跨领域的工具来分析这种网络的性能。在这个项目中产生的模型和解决方案的数学基础是最优化和博弈论。在这一努力过程中将产生的具体成果包括：合并信道感知和捕获的模型，更好地理解随机接入中机会主义的使用，最后，理解在多天线随机接入中分配自由度的方式。底层物理介质对接入方案性能的影响可能是相当大的，特别是在信道高度动态并且受周围环境中的无数变化影响的无线设置中。因此，结合复杂的分析技术来处理所产生的模型的物理介质的简洁表示是必不可少的，以挖掘从随机接入中使用信道感知所产生的收益。
