Abstract

An improved routing algorithm, the GPSR-S algorithm, is proposed for the problem that the GPSR protocol based on geographic position information in Vehicular Ad Hoc Networks (VANET) is not stable enough for communication links when forwarding data packets. According to the geographical position information of any vehicle nodes at different times, the algorithm calculates their running speed and movement direction respectively, and then calculates the Link Expiraion Time (LTE) of the communication link between the nodes by the speed and direction, taking into account the link stability and distance, and selects a reliable next hop. The network simulation platform NS-3 is used to simulate GPSR and GPSRS. In terms of packet delivery ratio and end-to-end delay, the GPSR-S algorithm outperforms the GPSR method, according to the results, making it more suitable for use in VANETs.
