Integrating Security into Quality-of-Service Based Routing and Mobility Management in Ad Hoc Wireless Networks

自组织无线网络具有支持随时随地、大规模无缝访问通信和计算资源的潜力。这样的网络虽然对应用程序非常有吸引力，但也带来了安全和服务质量提供方面的深刻问题。Adhoc网络依靠协作机制来适应由于节点的移动性而导致的网络拓扑的动态变化，而节点的移动性往往受到能量限制的限制。因此，这些网络很难保护，并且极易受到攻击。研究的总体目标是开发一个可扩展的自适应框架，将安全和服务质量(Qos)集成到商业和军事应用的自组织无线网络中路由和移动性管理的关键组件中。开发了一个可扩展的计算机仿真环境，以分析自组织网络在各种攻击场景、移动性模式和网络流量负载下保持服务质量的能力的安全强度。该研究调查了现有的路由和移动性管理方案的安全限制，并对这些方案进行了扩展，以纳入安全包容的服务质量属性。研究的重点是安全性和传统的服务质量参数(如性能、能量管理和可用性)之间的关键权衡。这项研究调查的安全机制可以防止或减轻恶意攻击的影响，而不会招致过多的开销。

Ad hoc wireless networks have the potential of supporting seamless anytime-anywhere access to communications and computing resources on a very large scale. Such networks, while extremely compelling for applications, pose profound problems of security and quality-of-service provisioning. Ad hoc networks rely on cooperative mechanisms that adapt to the dynamic changes in network topology due to the mobility of the nodes, which are often constrained by energy limitations. Consequently, these networks are difficult to secure and extremely vulnerable to attacks.The overall objective of the research is to develop a scalable and adaptive framework for integrating security and quality-of-service (QoS) into the critical components of routing and mobility management in ad hoc wireless networks for both commercial and military applications. A scalable computer simulation environment is developed to analyze the security strength of an ad hoc network with respect to its ability to maintain quality-of-service under a variety of attack scenarios, mobility patterns, and network traffic loadings. The research investigates the security limitations of existing routing and mobility management schemes and extends these schemes to incorporate security-inclusive QoS attributes. The focus of the research is on the critical tradeoffs among security and traditional QoS parameters such as performance, energy management, and availability. The research investigates security mechanisms that can prevent or mitigate the effects of hostile attacks without incurring excessive overhead.
