While current cellular networks are based essentially on one-to-many and many-to-one single-hop subnets and cope with inter-cell interference by careful centralized resource planning, future wireless networks must consider heterogeneous environments characterized by user-deployed and user-operated infrastructure in which multiple flows and multiple hops will play an increasingly relevant role. Indeed, such networks are expected to open doors to trillions of dollars of e-commerce, while also providing vast amounts of easily accessible knowledge to the public. Developing a fundamental understanding of multihop multiflow wireless networks is therefore critically important at this time.This exploratory project will seek to discover the fundamentals of such networks by obtaining their information theoretic capacity in an approximated sense. It is expected that scalable and extensible solutions are possible for such networks ranging from the seemingly simple ones involving two hops and two flows to apparently more complex ones involving multiple hops and more than two flows with arbitrary connectivity. In so demonstrating, multiple metrics will be employed. These metrics in the increasing order of accuracy in the high signal-to-noise ratio regime are (a) the fundamental limit on the available signaling (temporal/spectral/spatial) dimensions of the network, (b) the fundamental limit on the available signaling and signal-level dimensions, and (c) the capacity to within a (universal) constant number of bits independently of channel parameters.

虽然当前的蜂窝网络本质上基于一对多和多对一的单跳子网，并通过仔细的集中资源规划来应对小区间干扰，但未来的无线网络必须考虑以用户部署和用户部署为特征的异构环境。 - 运营的基础设施，其中多流和多跳将发挥越来越重要的作用。事实上，这样的网络预计将为价值数万亿美元的电子商务打开大门，同时也为公众提供大量易于获取的知识。因此，对多跳多流无线网络的基本理解此时至关重要。这个探索性项目将寻求通过获得近似意义上的信息理论能力来发现此类网络的基础知识。预计可扩展和可扩展的解决方案对于此类网络来说是可能的，从看似简单的涉及两跳和两个流的网络到明显更复杂的涉及多跳和具有任意连接的两个以上流的网络。在这样的演示中，将采用多个度量。这些指标在高信噪比状态下按准确度递增的顺序是（a）网络可用信令（时间/频谱/空间）维度的基本限制，（b）可用信令维度的基本限制。信令和信号级维度，以及 (c) 独立于信道参数的（通用）恒定位数的容量。
