  • Abstract
    Measurements and ongoing research have shown that WLAN connection for moving vehicles is feasible. However none of the previous works suggests a solution addressing a complete array of the challenges in vehicular WLAN communications. Our system, PEGASUS amends this by providing wireless connection roaming at high velocities. To the best of our knowledge, it is the first system that operates over "in situ" wifi networks, while at the same time offers transparency to user level applications by allowing a single IP address per user, and does not impose additional requirements to existing infrastructures. PEGASUS offers simple deployment, improved scalability, and is the first able to operate over secure "in situ" networks. It remains efficient under intermittent connectivity conditions and supports heterogeneous network mediums for increased robustness.
