Abstract
We address the joint problem of traffic routing and mobility support in wireless mesh networks that are built by many fixed nodes and few mobile nodes. We focus on a vehicular setting, where buses or streetcars connect to different fixed mesh nodes as they move in a urban environment. First, through simulation we identify the best candidate for routing traffic in such a scenario and we find that our improved version of the BATMAN protocol, named smart window BATMAN, outperforms other reactive and proactive approaches. Then, we develop a testbed which includes both roadside mesh nodes and vehicular mesh nodes. There, we implement the selected routing solution, along with a handover scheme that allows vehicles to connect to the different mesh nodes in a seamless manner. Our testbed and performance assessment show that mobility can be efficiently supported in mesh networks, and that our modified version of the BATMAN protocol is a good candidate for sustaining the handover of UDP streams in a seamless manner.Keywords
