Abstract	We present an architecture and discuss performance enhancement strategies for WLAN-based Internet access for moving vehicles. Measurements, on-going research activities and the development of first prototypes have shown that WLAN-based Internet access for moving vehicles is feasible and can be an interesting and cost-effective alternative to GSM/3G-based approaches. We present an approach that is based on the concept of "nearlynets", explicitly considering intermittent connectivity that can be limited to short periods of time. Based on measurements and simulations, we are developing an architecture enabling useful Internet connectivity when driving through isolated hotspots. This architecture supports mobility in such networks relying on application-layer mobility mechanisms. We also discuss transport and application protocol performance enhancements and operational issues such as detection of network access and address assignment.
