Abstract:
This paper presents and evaluates an IPv6-based protocol for the interconnection of ad hoc networks to the Internet. Its main novel feature is the support for different types of multihop handovers between two access routers. This topic represents an essential functionality of multihop radio access networks, but it has not been investigated so far in the context of a testbed. We measure and analyze the performance of different handover schemes in a testbed with IEEE 802.11b and ad hoc routing. We find that a proactive access router discovery scheme yields the lowest handover rate in our setup. Furthermore, it is advantageous to introduce optimizing multihop handovers, which gives mobile devices the opportunity to choose a new, better suited access router in case the hop distance to its current access router increases. Although this additional handover type increases the total number of handovers, it improves the system behavior in terms of handover delay and packet delivery fraction.
