Abstract
The goal of the MosquitoNet project is to provide continuous Internet
connectivity to mobile hosts. Mobile hosts must be able to take
advantage of the best network connectivity available in any location,
whether wired or wireless. We have implemented a mobile IP system that
supports seamless switching between different networks and
communication devices. In contrast to previous approaches to mobile
IP, we believe mobile hosts should not assume any explicit mobility
support from the networks they visit, aside from basic Internet
connectivity. This decision places extra responsibilities on the
mobile hosts themselves. In this paper, we describe the design and
implications of such a system. Measurements of our implementation show
that the inherent overhead to switch networks (below 10ms) is
insignificant compared to the time required to bring up a new
communication device.
