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.

当前的蜂窝网络主要基于一对多和多对一单跳子网，并通过仔细的集中资源规划来应对蜂窝间的干扰，而未来的无线网络必须考虑以用户部署和用户操作的基础设施为特征的异构环境，在这种环境中，多流和多跳将发挥越来越重要的作用。事实上，这样的网络有望为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，发展对多跳多流无线网络的基本理解在此时是至关重要的。这个探索性项目将通过获得近似意义上的信息理论能力来寻求发现这种网络的基础。对于这样的网络，从涉及两个跳点和两个流的看似简单的网络到涉及多个跳点和具有任意连接的两个以上流的明显更复杂的网络，期望可扩展和可扩展的解决方案是可能的。在这样的演示中，将使用多个度量标准。在高信噪比条件下，这些指标按精度递增的顺序是(a)网络可用信令（时间/频谱/空间）维度的基本限制，(b)可用信令和信号级维度的基本限制，以及(c)独立于信道参数的（通用）恒定位数内的容量。
