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基本上基于一对多和一对一的单跳子网，并通过仔细的集中资源计划来应对内部的干扰，但未来的无线网络必须考虑以用户剥夺和用户为特征的异质环境 - 多个流动和多个啤酒花将发挥越来越相关的作用的基础架构。确实，这些网络有望为数万亿美元的电子商务打开大门，同时还向公众提供大量易于获得的知识。因此，在此时对MultiHop Multiflow Wireless网络的基本了解至关重要。此探索性项目将寻求通过以近似意义获得其信息理论能力来发现此类网络的基础。可以预期，对于从涉及两个啤酒花和两个流的看似简单的网络到显然涉及多个啤酒花和两个以上具有任意连通性的流动的更复杂的网络，可以进行可扩展和可扩展的解决方案。因此，将采用多个指标。这些指标以高信噪比的越来越高的准确性顺序是（a）网络的可用信号传导（时间/光谱/空间）维度的基本限制，（b）可用的基本限制信号传导和信号级尺寸，以及（c）独立于通道参数的（通用）恒定位数内部位置的能力。
