In this paper, we investigate efficient strategies for supporting velocity aware probabilistic route discovery in Mobile Ad hoc Networks (MANETs). MANETs usually use broadcast mechanisms to discover routes between nodes by flooding the network with RREQ packets. Usually, the routes of the high mobility nodes have frequent breakages which result in re-discovering the same routes frequently. Hence, uncontrolled RREQ packets can cause more channel contention and increase packets collision rate. This is well-known as the broadcast storm problem where different probabilistic solutions have been suggested to mitigate its side effect. To the best of our knowledge, this study is the first that considers the velocity vector probabilistic route discover in MANETs. Precisely, this study proposes a new Velocity Aware-Probabilistic (VAP) route discovery model, which can exclude unstable nodes while constructing routes between the source and its destination. Our simulation experiments confirm that our proposed model significantly outperforms existing well known solutions in terms of RREQ packet overhead and link stability.
