Performance Analysis of Various Congestion Control Schemes in VANET

Abstract

Vehicular Ad hoc Networks (VANETs) are intended to give compact remote interchanges between rapid moving vehicles. In a way to improve the execution of applications related to VANETs, and design a comfort and safe condition for VANETs clients, Quality of Service (QoS) ought to be upheld in such systems. The packet loss and message delay are basic fundamental markers of QoS that drastically rise because of the occurrence of congestion in the systems. Congestion results in congestion of channels and packet collisions due to which delay and packet loss also increases, thus results in the degrade of VANET performance. Therefore, congestion should be controlled in order to increase the performance of VANET by evading delay and packet losses. In this paper different types of congestion control schemes have been studied and evaluated by considering the remote and urban areas under the scenario of VEINs framework. Correlations were additionally made between the existing congestion control schemes in VANET. Results obtained from the simulations reflects that the scheme mentioned in AC3 [13] performs better on the basis of ratio of throughput, packet loss, and average delay as compared to other existing congestion control schemes in VANET.
