Interference is a fundamental feature of the wireless medium and a major performance bottleneck in the engineering of wireless networks. However, the broadcast nature of the wireless medium which manifests itself in the form of interference can also be a benefit in disguise. It allows multiple nodes to receive a common signal and generates the potential for cooperation. Much of the fundamental research effort on the broadcast aspect so far has addressed these two aspects (interference and cooperation) separately. This project studies interference management and cooperation in a common context and a holistic manner.The research conducted in this effort (a) looks for novel communication strategies that harness the broadcast advantage while minimizing its interfering nature; (b) looks to identify engineering contexts where the novel communication strategies provide the most gain over traditional approaches; and (c) looks to characterize novel fundamental outer bounds (beyond the cut-set ones) to rates of reliable network communication where cooperation and interference coexist. These goals are addressed by starting out with simple (but canonical) models of wireless networks featuring two unicast traffic under three formulations that cover a wide range of issues in wireless networks: (i) cooperative networks such as cellular networks, (ii) competitive networks or networks with restricted cooperation such as Wi-Fi, and(iii) heterogenous networks involving cognitive radios.

干扰是无线介质的基本特征，也是无线网络工程中的主要性能瓶颈。但是，以干扰形式表现出来的无线介质的广播性质也可能是伪装的好处。它允许多个节点接收一个共同的信号并产生合作的潜力。到目前为止，关于广播方面的许多基本研究工作已经分别解决了这两个方面（干预与合作）。该项目以共同的环境和整体方式研究干预管理与合作。在这项工作中进行的研究（a）寻找新颖的交流策略，以利用广播优势，同时最大程度地减少其干扰性质； （b）旨在确定新颖的沟通策略比传统方法最大收获的工程环境； （c）希望将新颖的基本外部边界（超越切割设定的外部边界）描述为可靠的网络通信速率，而合作和干扰共存。这些目标是通过以简单的（但规范）的无线网络模型来解决的，这些模型在三种公式下进行了两个单层流量，涵盖了无线网络中的各种问题：（i）诸如蜂窝网络（ii）竞争性网络或具有限制性合作的合作网络，例如WI-FI，以及（III）和（iii）的异源性网络，包括竞争性的网络或网络。
