Security Management in Ad Hoc Wireless Networks

自组织网络的目的是在其他一切都不可能的情况下提供通信。在某些情况下确实是这样，例如战术现场通信、自然灾害和紧急情况。我的目标是为在自组织网络上的安全通信做出贡献，使其达到与在基础设施网络（例如，蜂窝网络）上实现的通信相当的水平。这是具有挑战性的，因为特设网络不提供基础设施网络所提供的资源和稳定性。我的长期目标是：-精心设计的原始协议元素，导致在特设网络上的安全通信。-研究自组织网络中安全性和服务质量之间的相互作用。-将使用自组织网络的解决方案组合在一起，以解决现实生活中的通信问题。我倾向于采用整体方法，同时考虑到与安全管理相关的高度交互的实际方面，例如容错、重新配置、会计和性能。理论与实践相结合。合理的原则是根据现实的和经过验证的假设制定的。我将把我的大部分研究时间用于无线通信安全。在接下来的几年里，我想把重点放在新兴技术所能实现的三个特定领域：-在考虑安全和服务质量的情况下，为特设网络上的多媒体流量提供自适应协议。-在认知自组织无线网络中，确保二次频谱用户选择公共信道。-在兼顾安全和效率的情况下，从基础设施到特设网络的转换。-考虑到安全性、效率和服务质量，在特设网络中提供健壮的链路状态路由。

Ad hoc networks aim at providing communications when everything else is not possible. There are scenarios where this is indeed the case such as tactical field communications, natural catastrophes and emergencies. My goal is to contribute towards secure communications over ad hoc networks to a level comparable to the one achieved on infrastructure networks (e.g., cellular networks). This is challenging because ad hoc networks do not offer the resources and stability presented by infrastructure networks.My long term objectives are:- Elaborate original protocol elements leading to secure communications over ad hoc networks.- Investigate the interaction between security and quality-of-service in ad hoc networks.- Put together solutions that use ad hoc networks to solve communication issues in real life scenarios.I favour a holistic approach where highly interacting practical aspects related to security management are simultaneously taken into account, such as fault-tolerance, reconfiguration, accounting and performance. Theory and practice are combined. Sound principles are developed based on realistic and verified assumptions. I will dedicate most of my research time to wireless communications security.For the upcoming years, I want to concentrate on three particular areas enabled by emerging technologies:- Adaptive protocols for multimedia traffic over ad hoc networks, taking into account security and quality-of-service.- Secure common channel selection by secondary spectrum users in cognitive ad hoc wireless networks. - Handovers from infrastructure to ad hoc networks, taking into account security and efficiency.- Robust link-state routing in ad hoc networks, taking into account security, efficiency and quality-of-service.
