Securing AODV: the A-SAODV secure routing prototype

Abstract

Mobile ad hoc networks pose new kinds of security problems, caused by their nature of collaborative and open systems and by limited availability of resources. In this article, we consider a Wi-Fi connectivity data link layer as a basis and focus on routing security. We discuss our implementation of the secure AODV protocol extension, which includes tuning strategies aimed at improving its performance. Namely, we propose an adaptive mechanism that tunes SAODV behavior. Moreover, we analyze our adaptive strategy and another technique that delays the verification of digital signatures. This article sums up the experimental results we collected in the prototype design, implementation, and tuning.
