TCP and Priority Queue based Emergency Data Transmission in VANETs

A vehicular ad hoc network (VANET) can be used to share data and provide services to moving vehicles on the road. Vehicles can transmit a variety of messages, including both safety and non-safety-related or entertainment-related messages. Certain vehicles may need to transmit emergency messages and those messages are crucial to the network. Prioritizing the messages will help them be transmitted more quickly. The priority system used in this study places Emergency messages, General Messages, and Entertainment messages in order of importance. Entertainment is given low priority, general message is given medium priority, and emergency communication is given high priority. To assign flags to the messages, we use the TCP protocol.
