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.

自组织无线网络具有支持随时随地无缝访问大规模通信和计算资源的潜力。 此类网络虽然对应用程序极具吸引力，但也带来了安全和服务质量供应方面的深刻问题。 自组织网络依赖于适应由于节点移动性而导致的网络拓扑动态变化的协作机制，而节点的移动性通常受到能量限制。 因此，这些网络很难保证安全，并且极易受到攻击。该研究的总体目标是开发一个可扩展的自适应框架，将安全性和服务质量 (QoS) 集成到路由和移动性管理的关键组件中。用于商业和军事应用的自组织无线网络。 开发了一个可扩展的计算机模拟环境，用于分析自组织网络的安全强度，以及在各种攻击场景、移动模式和网络流量负载下维持服务质量的能力。 该研究调查了现有路由和移动性管理方案的安全限制，并将这些方案扩展为包含安全的 QoS 属性。 研究的重点是安全性和传统 QoS 参数（例如性能、能源管理和可用性）之间的关键权衡。该研究调查了可以防止或减轻恶意攻击的影响而不会产生过多开销的安全机制。
