This paper discusses new mobile usage scenarios for WLAN technologies
and presents an architecture that is based on the notion of
intermittent connectivity instead of seamless connectivity. The
Drive-thru Internet approach is intended to support Internet
applications of mobile users in environments where no permanent
connectivity is available, a common case for nomadic users. We have
chosen the extreme scenario of users in vehicles moving at high speed
on the road and provide connectivity by means of WLAN access points.
Our service architecture takes the transient character of local
network access into account and provides for persistent transport
connections and application layer mobility. From reviewing common
Internet applications, we derive application-specific extensions to
optimize various kinds of protocols and provide a concrete usage
example. We also discuss the relation of Drive-thru Internet to
technologies such as network layer mobility, authenticated network
access, common WLAN hot spot setups, and WLAN roaming.
