B. A. T. M. A. N. Handover Extension for Routing Nodes in Infrastructure WMNs

Abstract

In the past, several proposals to support fast handover in wireless mesh networks have been published. However, most handover extensions are only concerned with moving stations that are unaware of the used routing protocol and assume relatively stationary routing nodes. In this paper we propose an extension to the BATMAN routing protocol to support seamless handover of routing nodes in infrastructure wireless mesh networks. We implement the new extension in our wireless mesh testbed and evaluate its performance in comparison to a standard WLAN handover followed by a route reestablishment using BATMAN. The evaluation shows that route reestablishment is more than 40 times faster with our extension when compared to standard BATMAN.
