项目摘要
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多对一的单跳路由,并通过仔细的集中式资源规划来科普小区间干扰,但未来的无线网络必须考虑以用户部署和用户操作的基础设施为特征的异构环境,其中多个流和多跳将发挥越来越重要的作用。事实上,这些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。发展多跳多流无线网络的基本理解,因此在这个时候是至关重要的。这个探索性的项目将寻求发现这种网络的基本原理,通过获得他们的信息理论容量在近似的意义。预计这种网络的可扩展性和可扩展的解决方案是可能的,从看似简单的涉及两个跳和两个流的网络到显然更复杂的涉及多个跳和两个以上的流与任意连接的网络。在这样的演示中,将采用多个指标。在高信噪比机制中,这些度量的准确性以递增的顺序为(a)对网络的可用信令(时间/频谱/空间)维度的基本限制,(B)对可用信令和信号电平维度的基本限制,以及(c)独立于信道参数的(通用)恒定比特数内的容量。
