Implementation of a security framework for wireless multi-hop networks

Wireless Multi-hop Networks represents an emerging technology for next-generation wireless networking. Although very little attention has been devoted so far to the security issues of this technology, they represent a critical feature that can limits the employment of this technology as a convenient alternative to others networking solutions. In this demo we present an implementation of a security framework for Wireless Multi-hop Networks that provides authentication and access control of wireless nodes as well as a key distribution scheme. We compare our security framework both with a static key approach and with an end-to-end solution that consists in establishing an encrypted IPSec tunnel. The experimental analysis shows that our solution enhances the network security with a negligible impact on the network performance, thus representing an effective solution for wireless multi-hop networking.
