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 some tuning strategies aimed at improving its performance. Namely, we propose an adaptive mechanism that tunes SAODV behaviour. Moreover, we analyse our adaptive strategy and another technique that delays the verification of digital signatures. This paper sums up the experience we collected in the prototype design, implementation and tuning.
