A Timely VANET Multi-hop Routing Method in IoT

Vehicular Ad hoc Networks (VANET) is a promising technology in the Internet of Things (IoT) which enables communication in vehicle to vehicle (V2V) and vehicle to infrastructure (V2I). VANETs attracts great attention in various applications such as automakers, universities, and traffic police. There are some challenges that to be addressed. The main challenge is routing due to high speed movement of vehicles. Several methods have been proposed to tackle the problem of end-to-end delay in routing. They are still issues from delay to select next-hop relay node. This delay in dense environment broadcast storm problem. Therefore, we proposed new multi-hop routing method that takes the advantages of periodic hello messages to conduct routing tables and select efficient node for rebroadcasting messages. In order to show the performance of the proposed method, extensive results carried out using Network Simulator (NS2) and compare it with other related routing methods. The simulation results indicates that removing contention phase to select rebroadcast node results better end-to-end delay and reduce redundant packets.
