This project investigates the concept of cooperation between nodes in a wireless network to increase its traffic capacity and reduce radio interference. Currently, transmissions between two nodes overheard by a third node are discarded. It has been shown that this overheard information can be used by the third "helper", through additional transmissions, to increase the capacity of the network. Alternatively, the cooperating nodes can also reduce the power needed to transmit the same amount of information as a network without cooperation. The notion of cooperation will be investigated both for the actual bits being transmitted, as well as in the medium access and routing protocols that facilitate and exploit it. The research will consider ad hoc networks in addition to infrastructure-based networks.This work shows how to increase the capacity of wireless networks, and allow for a better spatial reuse of a limited amount of bandwidth by reducing the interference to other nodes in the vicinity. Analysis, simulations and proof of concept implementations are used in this research. Broader impacts, besides the research itself, include the positive outcomes of joint work with industry partners, and involving a wide group of students in research through the implementation-related projects.

该项目调查了无线网络中节点之间的合作概念，以增加其流量并减少无线电干扰。当前，丢弃了两个节点之间的两个节点之间的传输。已经表明，通过额外的传输，可以使用第三个“助手”来使用此偷听的信息来增加网络的容量。 另外，协作节点还可以降低传输与网络相同的信息而无需合作所需的功率。合作的概念将被调查，包括要传输的实际位，以及促进和利用它的中等访问和路由协议。 该研究还将考虑基于基础架构的网络之外的临时网络。这项工作显示了如何提高无线网络的能力，并通过减少附近其他节点的干扰来更好地对有限的带宽进行更好的空间重复使用。本研究使用了分析，模拟和概念实现证明。 除研究本身外，更广泛的影响还包括与行业合作伙伴共同合作的积极成果，并通过与实施相关的项目使许多学生参与研究。
