In VANET, various limitations such as high mobility, high rate of topology changes, limitation of bandwidth, etc, play a significant role for reducing performance in these networks. Qualities of Service policies have been used to improve the performance of VANET. One of the significant parameters in Quality of Service is Congestion Control. The congestion control is used to ensure safe and reliable communication architecture. Three types of strategies are available for congestion control which consists of transmission power control, packet transmission frequently control and packet duration. Heuristic techniques can be used to define heuristic rules and finding feasible and good enough solution to some problems in reasonable time. According to heuristic's benefits, we are motivated to use these techniques in congestion control to generate efficient VANET. This work is aimed to improve congestion control with heuristic techniques to reduce the traffic communication channels while considering reliability requirements of applications in VANETs. The simulation results have demonstrated that meta-heuristic techniques features significantly better performance in terms of packet loss, throughput and delay compared with other congestion control algorithm within VANETs.
