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.

该项目研究无线网络中节点之间合作的概念，以增加其流量容量并减少无线电干扰。目前，第三个节点监听到的两个节点之间的传输被丢弃。事实证明，第三个“助手”可以通过额外的传输来使用这些偷听的信息，以增加网络的容量。 或者，协作节点还可以减少与不进行协作的网络传输相同量的信息所需的功率。合作的概念将针对正在传输的实际比特以及促进和利用它的媒体访问和路由协议进行研究。 除了基于基础设施的网络之外，该研究还将考虑自组织网络。这项工作展示了如何增加无线网络的容量，并通过减少对附近其他节点的干扰来更好地空间重用有限的带宽。本研究使用了分析、模拟和概念验证实施。 除了研究本身之外，更广泛的影响还包括与行业合作伙伴合作的积极成果，以及通过实施相关项目让广大学生参与研究。
