Cooperative transmission is an emerging wireless communication paradigm that improves wireless channel capacity by creating multi-user cooperation in the physical layer. In cooperative transmission, when the source node transmits a message to the destination node, the nearby nodes that overheard this transmission will "help" the source and destination by relaying the replicas of the message, and the destination will combine the multiple received waveforms so as to improve the link quality. This technology departs from the traditional point-to-point link abstraction of wireless connections, and is expected to have a profound impact on network performance and design. The current algorithm design, protocol development and performance evaluation for cooperative transmission assume that all wireless nodes are trustworthy. Investigation of the security issues is lagging behind. This research addresses the major security issues related to cooperative transmission. In particular, does cooperative transmission provide new opportunities for attackers to undermine network performance? Conversely, are there new ways to defend wireless networks through physical layer cooperation? Any project in an open area in security benefits the larger society which now has urgent need of true innovations in security. In addition, this project will have broader impacts through its education plan, which focuses on an outreach program integrating campus summer camps for high school-age women/minority students and an online mentoring group, in addition to graduate and undergraduate student participation. In summary, the PIs are equally dedicated to improving wireless network performance through security-assured cooperative transmission and to enhancing female and minority participation in engineering.

合作传输是一种新兴的无线通信范式，可通过在物理层中创建多用户合作来改善无线通道容量。在合作传输中，当源节点将消息传输到目标节点时，偷听此传输的附近节点将通过中继消息的复制品来“帮助”源和目的地，并且目的地将结合多个接收到的波形，以提高链接质量。这项技术脱离了无线连接的传统点对点链接抽象，预计将对网络性能和设计产生深远的影响。当前的合作传输算法设计，协议开发和性能评估假设所有无线节点都是值得信赖的。对安全问题的调查落后。这项研究解决了与合作传播有关的主要安全问题。特别是，合作传播是否为攻击者提供了破坏网络性能的新机会？相反，是否有新的方法可以通过物理层合作来捍卫无线网络？安全区域中的任何项目都使较大的社会受益于现在迫切需要在安全方面进行真正的创新。此外，该项目将通过其教育计划产生更大的影响，该计划的重点是将校园夏令营整合到高中女性/少数民族学生和在线指导小组中，除了研究生和本科生的参与外。总而言之，PIS同样致力于通过安全保存的合作传播来提高无线网络性能，并增强女性和少数群体参与工程。
