Cross-Layered Security Analysis of Wireless Ad Hoc Networks

Abstract : There is an inherent tradeoff between the performance of a network and its security. In this work we explore possible evaluations of security threats versus the cost of prevention and reaction to such threats. We consider different kind of adversaries with different capabilities. We present the effect of these capabilities on the different layers and the network as a whole. Such a study will help identify the importance of layered security in this infrastructure-less wireless setting.
