NeTS: Small: Design and Initialization of Secure Wireless Networks: Foundations and Practice

无线自组织网络已成为节点之间在没有基站等基础设施的情况下进行通信的关键技术。它将用于各种应用，包括无线传感器网络、灾难恢复和军事现场通信。无线自组织网络在协议栈、MAC、路由、拥塞控制等各个层面都取得了重大进展，并着眼于配置网络以优化诸如容量、连接、延迟等指标。然而，仍然有许多问题没有得到令人满意的处理，从识别网络配置到优化新出现的安全指标，到如何实现各种理想的网络配置：即，一个自组织网络如何引导自己实现承诺的性能和安全性？我们在研究中解决了这个问题。我们特别关注以下方面：？无线网络安全：描述在存在窃听者和/或干扰者的机会性无线网络中性能和安全性之间的权衡，并开发在此类环境中提供安全通信的算法。无线网络配置：在部署时配置网络，特别注意根据需要方便选择“友好干扰器”和机会中继器，以增强安全性。这项研究的结果将构成理论基础、实用算法和网络架构发展的重大进步，用于配置和保护无线网络。

Wireless ad hoc networking has become a critical technology for nodes to communicate with each other in the absence of infrastructures such as base stations. It will be used in a variety of applications including wireless sensor networks, disaster recovery, and military on-the-field communications.Significant advances have been made in the area of wireless ad hoc networking at all levels of the protocol stack, MAC, routing, congestion control, etc., with an eye toward configuring networks so as to optimize metrics such as capacity, connectivity, delay, etc. However, there remain numerous issues that have not been satisfactorily dealt with, ranging from identifying network configurations to optimize emerging security metrics, to how to effect various desirable network configurations: namely, how does an ad hoc network bootstrap itself to realize the promised performance and security? We address this question in our research. Specifically we focus on the following:? Wireless network security: Characterize the tradeoff between performance and security in opportunistic wireless networks where eavesdroppers and/or jammers are present, and develop algorithms for providing secure communication in such environments.? Wireless Network configuration: Configure networks at the time of deployment, paying particular attention to facilitating the selection of "friendly jammers" and opportunistic relays as needed to enhance security.The outcome of this research will constitute a significant advance in the development of theoretical foundations, practical algorithms, and network architecture for configuring and securing wireless networks.
