Abstract

Data dissemination in vehicular ad hoc networks (VANETs) has recently received considerable attention. Due to the unique characteristics of VANET, the implementation of reliable data dissemination among vehicles has encountered many challenges. In this paper, a reliable and efficient data dissemination scheme is presented. Relative locations between neighbor vehicles are predicted to improve delivery reliability. Based on assisted nodes which could customize the amount of data according to drivers´ different requirements, the novel scheme increases the network connectivity while reducing redundant network traffic. Simulation results show that our novel scheme can obviously improve the network performance in terms of data dissemination rate and data dissemination delay.
