Improved routing in VANET networks by the proposed machine-based algorithm

The vehicular ad hoc network (VANET) provide an attractive platform for intelligent transportation One of the well-known routing protocols in VANET is the AODV routing protocol. Applying this routing protocol on VANET also has problems that with increasing network scale and nodes, the number of control messages increases in the network. The AODV routing protocol uses the criterion of the least number of steps in the route selection, which reduces network performance and does not select more stable routes. In this research, two methods for routing are presented that somewhat improve the mentioned problems. The first proposed method is a clustering method that has been proposed to reduce the number of control messages. The second proposed method has been proposed to solve the rout selection problem which we have solved using Bayesian algorithm. The criteria used to evaluate the performance of these methods are increasing the package delivery rate and decreasing the package loss rate and the average end-to-end delay.
