摘要

The Traffic congestion is the major problem in urban areas and solution is only to efficiently utilize the bandwidth and handle congestion occurrence properly in network. The Road Side Units (RSUs) are playing the important role to manage congestion. In this research, proposes a Data Rate and Channel-aware congestion management Approach (DRCA) for bandwidth utilization and delay minimization in VANET. Here the DRCA is responsible for collecting information about the available channel, the interference level, and the signal-to-noise ratio of nodes. If the channel is available, the interference level is low, and the signal-to-noise ratio is higher than RSU. Select the intermediate node and obtain the destination node using the DRCA mechanism; otherwise, stop forwarding the routing packet to the next hop and discard it. The performance of proposed DRCS scheme is compare with ABGR and DSRC schemes but performance of DRSC is better in all different vehicle’s density scenarios. The performance of all the approaches is compared with performance metrics like PDR, Delay, Overhead and data packets dropping. The minimum improvement in performance of DSRC is 5% in all the given metrics and maximum is more or equal to 10%. The proposed DRCS scheme not only handle the congestion but also improving the routing performance without extra overhead of transfer traffic status in network.
