Congestion control scheduling scheme for vehicular networks

Abstract

The vehicular Ad hoc network is new emerging technology to enhance traffic safety and comfort for automotive users. Most of the safety applications in this field need real time information with high reliability and in time delivery. In dense network a large number of vehicles nodes disseminate the messages to all accessible nodes with high frequency and control channels will be easily congested and cause of broadcast storm. There is a need to prevent control channels from these types of storms and ensure the reliable and in time devilry of messages for safety applications. The congestion control mechanism is one of the most popular approach to control the load and ensure in time and efficient delivery of messages. We proposed a congestion control scheduling scheme to provide an efficient operation, congestion avoidance or mitigation. The performance of proposed scheme is evaluated in different congested scenarios and compared with existing congestion control scheduling schemes and improve packet loss rate and packet delay.
