An Efficient Scheme for Reliable File Transfer using Residual Link Lifetime Estimation based on Sparse Vehicular Routes

Abstract

Abstract Abstract. Location based networking protocols in Vehicle Ad-Hoc Networks (VANETs) employ the hopping strategy to acquire the route to a destination node. One of the commonly used methods is to select the vehicle that is nearest to their destination. This greedy transmission approach leads to packet drop in disruptive networks like VANETs, since it doesn’t take account of the quality of the newly-established links. In this article, a new method is proposed for identifying the next-hop node from a potential set which takes account of the remaining life of the contact connections combined with the vehicular movement. Compared with the existing idea of predicting the new location using Kalman filters, the proposed method is based on vehicular density in the path to destination.
