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.

本计画探讨无线网路中节点间合作的概念，以增加网路的流量并减少无线电干扰。目前，被第三节点偷听的两个节点之间的传输被丢弃。已经表明，第三个“助手”可以通过额外的传输来使用这种偷听到的信息，以增加网络的容量。 可替换地，协作节点还可以减少传输与没有协作的网络相同量的信息所需的功率。合作的概念将被调查的实际比特传输，以及在介质访问和路由协议，促进和利用它。研究将考虑ad hoc网络除了基于基础设施的网络。这项工作表明如何增加无线网络的容量，并且通过减少对附近其它节点的干扰来允许有限带宽量的更好空间重用。在这项研究中使用的分析，模拟和概念实现的证明。 除了研究本身之外，更广泛的影响包括与行业合作伙伴联合工作的积极成果，以及通过实施相关项目让广泛的学生参与研究。
