In muti-owner wireless networks, access points (AP) are owned and operated by different administrationsleading to significant authentication delays during handoff between APs. We propose to exploittrust between the owners of neighboring APs for reducing the authentication delay. In the proposedauthentication scheme, neighboring APs that trust each other share the security key for the visitingnode to avoid lengthy authentication routines each time the visiting node switches access points. Theperformance of the proposed trust-based authentication scheme is evaluated using a Markov model.Using numerical experiments, we first study a basic scenario where mobile nodes are not aware ofthe trust networks that exist in a given neighborhood. Subsequently we consider an advanced scenariowhere mobile node functionality is augmented to discover the trust network so as to minimize roamingbeyond the trusted APs. We find that even with the basic implementation, the average number of fullauthentications needed for a roaming mobile reduces linearly as the likelihood of two neighboring APstrusting each other increases. With the advanced implementation, our experiments show that quadraticreduction is achieved. The Markov model is validated using discrete event simulation.
