A Improved Routing Scheme Based On Link Stability For Vanet
conference on industrial electronics and applications(2019)
摘要
VANET(vehicular ad hoc network) generally achieves long-distance data transmission through multi-hop forwarding. Due to the high-speed mobility, uneven distribution, and the behavior of the vehicle, the VANET network topology changes dynamically and the network is prone to breakage. How to choose the next hop node is the key to implement the routing method. Link stability is an important factor to measure the performance of VANET. In this paper, the Kalman filter based strategy is used to predict speed of nodes, and the routing algorithm based on fuzzy logic to predict link stability is improved. The simulation results show that compared with the traditional AODV, the proposed method has a great improvement in routing stability.
