Improving QoS in VANET

 The Vehicular Ad Hoc Network (VANET) is a novel and auspicious performance within the Intelligent Transportation Systems (ITS) field. Numerous scholars endeavoured to enhance the VANETs' Quality of Service (QoS) by creating routing procedures that were reliable, scalable, and efficient. One of the most significant issues of vehicular networks is building a routing protocol that guarantees a specific level of quality of service (QoS), as VANETs are distinguished by special properties, including constrained mobility, a very dynamic topology, and high node speed. For drivers to be able to make the right decisions, communication between vehicular nodes must be highly reliable. Link breakdown issues typically lower the quality of service (QoS) of a vehicular ad hoc network (VANET). This, in turn, lowers the following parameters that influence the QoS. This method depends on a for parameter Packet parameter of Delivery Ratio (PDR ), Packet Loss, Delay of End to End, and Throughput. The simulation results show that the proposal protocol has increased the longevity effectiveness of the network by around (PDR) 93%, Loss of packet 6%, (E2ED) 45.6 seconds, and Throughput 1500/ bps.
