NeTS-NBD: Cooperative Wireless Communications: From Coding to Networking

本项目研究无线网络中节点之间的合作概念，以增加其流量容量并减少无线电干扰。目前，两个节点之间的传输被第三个节点偷听后被丢弃。已经证明，第三个“助手”可以通过额外的传输来使用这些无意中听到的信息，以增加网络的容量。或者，合作节点也可以减少传输相同数量信息所需的功率，因为没有合作的网络。将对正在传输的实际比特以及促进和利用它的媒介访问和路由协议中的合作概念进行研究。除了基于基础设施的网络外，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允许有限带宽的更好的空间重用。本研究使用了分析、仿真和概念验证实现。除了研究本身外，更广泛的影响还包括与行业合作伙伴共同工作的积极成果，以及通过实施相关项目使广泛的学生群体参与研究。

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.
