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

无线自组织网络已经成为节点在缺乏诸如基站的基础设施的情况下彼此通信的关键技术。无线自组织网络在协议栈、MAC层、路由、拥塞控制等各个层次上都取得了显著的进展，着眼于配置网络以优化诸如容量、连通性、延迟等的度量。然而，仍然存在许多尚未令人满意地处理的问题，其范围从识别网络配置以优化新兴的安全度量到如何实现各种期望的网络配置：即，自组织网络如何引导自身以实现所承诺的性能和安全性？我们在研究中提出了这个问题。具体而言，我们专注于以下几点：无线网络安全：描述存在窃听者和/或干扰器的机会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，特别注意根据需要促进“友好干扰器”和机会中继的选择，以增强security.The研究的结果将构成一个重大的进步，在理论基础，实用算法和网络架构的发展配置和安全的无线网络。

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.
