Efficient routing is one of the key challenges of wireless networking forunmanned autonomous vehicles (UAVs) due to dynamically changing channel andnetwork topology characteristics. Various well known mobile-ad-hoc routingprotocols, such as AODV, OLSR and B.A.T.M.A.N. have been proposed to allow forproactive and reactive routing decisions. In this paper, we present a novelapproach which leverages application layer knowledge derived from mobilitycontrol algorithms guiding the behavior of UAVs to fulfill a dedicated task.Thereby a prediction of future trajectories of the UAVs can be integrated withthe routing protocol to avoid unexpected route breaks and packet loss. Theproposed extension of the B.A.T.M.A.N. routing protocol by a mobilityprediction component - called B.A.T.Mobile - has shown to be very effective torealize this concept. The results of in-depth simulation studies show that theproposed protocol reaches a distinct higher availability compared to theestablished approaches and shows robust behavior even in challenging channelconditions.
