The CHARIoT network advances the idea that hybrid wireless networks can draw on the combined strengths of fixed and ad-hoc networks to create a vital architecture for the next generation Internet. Common to the various scenarios of hybrid networks are infrastructure nodes that act as relays for intra-network communications and as gateways for communications with external entities. Infrastructure nodes are typically connected to a powerful "backbone" with high capacity and low latency. Hybrid networks have been proposed in the literature for providing relief to the scalability problem of vanishing per node throughput in ad-hoc wireless networks. However, these studies have also shown that to restore scalable throughput, infrastructure nodes have to scale at the same rate as the user nodes, dooming this approach economically. When multiple users share the same link, wireless channels behave as "leaky pipes" interfering with each other. A totally new dimension is introduced by allowing nodes to cooperate. Cooperation among user or infrastructure nodes has the ability to convert "leaky channels" into high capacity multidimensional manifolds. A central question that CHARIoT seeks to answer is: Can cooperation among infrastructure nodes resolve the scalability problem of hybrid networks in the sense that in a cooperative regime, non-vanishing per node throughput is achievable even when the number of infrastructure nodes scales considerably slower than the number of user nodes? Intellectual Impact: The proposed research seeks to answer pivotal fundamental and design questions on the role of hybrid networks and cooperative regimes as part of the next generation Internet.Broader Impact: Advances in wireless technology and consumers demand for unfettered access usher in an era in which personal computing devices will become pervasive. This will lead to new communications paradigms that cannot be addressed by conventional network architectures. CHARIoT will have a broad impact on society by helping to determine whether wireless hybrid networks can play an important role in interconnecting pervasive devices and whether cooperative regimes can facilitate economically sensible designs of these networks. In addition to the impact on society, the extensive research provides an exciting platform for the educational goals of the academic institutions, including activities for both undergraduates and graduate students.

战车网络提出了一种想法，即混合无线网络可以利用固定网络和自组织网络的综合优势，为下一代互联网创建一个重要的架构。混合网络的各种场景都有基础设施节点，它们充当网络内部通信的中继，并充当与外部实体通信的网关。基础设施节点通常连接到具有高容量和低延迟的强大“骨干”。文献中提出了混合网络，以缓解自组织无线网络中每个节点吞吐量消失的可扩展性问题。然而，这些研究也表明，为了恢复可扩展的吞吐量，基础设施节点必须以与用户节点相同的速率进行扩展，这在经济上注定了这种方法的失败。当多个用户共享同一链路时，无线信道就像“漏管”一样相互干扰。通过允许节点合作，引入了一个全新的维度。用户或基础设施节点之间的合作能够将“泄漏通道”转换为高容量多维流形。战车试图回答的一个核心问题是：基础设施节点之间的合作能否解决混合网络的可扩展性问题，即在合作机制中，即使基础设施节点的数量比用户节点的数量扩展得慢得多，也可以实现每个节点的吞吐量不消失？智力影响：拟议的研究旨在回答关于混合网络和合作机制作为下一代互联网一部分的作用的关键基础和设计问题。更广泛的影响：无线技术的进步和消费者对自由访问的需求开启了个人计算设备普及的时代。这将导致传统网络架构无法解决的新通信范式。战车将通过帮助确定无线混合网络是否可以在互连无处不在的设备中发挥重要作用，以及合作机制是否可以促进这些网络的经济合理设计，从而对社会产生广泛的影响。除了对社会的影响，广泛的研究为学术机构的教育目标提供了一个令人兴奋的平台，包括本科生和研究生的活动。
