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

Ad hoc无线网络具有支持对通信和计算资源进行大规模的随时随地无缝访问的潜力。 这样的网络，虽然非常引人注目的应用程序，提出了深刻的安全和服务质量的供应问题。 Ad hoc网络依靠协作机制来适应网络拓扑的动态变化，由于节点的移动性，这往往是由能量限制。 因此，这些网络是很难安全和非常容易受到攻击的总体目标的研究是开发一个可扩展的和自适应的框架集成的安全性和服务质量（QoS）到Ad Hoc无线网络的路由和移动性管理的关键组成部分，为商业和军事应用。 一个可扩展的计算机仿真环境的开发，以分析一个ad hoc网络的安全强度，其能力，以保持服务质量的各种攻击的情况下，移动模式，和网络流量负载。 研究调查现有的路由和移动性管理计划的安全限制，并扩展这些计划，将安全包容的QoS属性。 研究的重点是安全性和传统的QoS参数，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影响而不会产生过多开销的安全机制。

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.
