Communication based accident avoidance and congestion control mechanism in VANETs

Today in urban areas accident is a big problem that causes loss of human life and property. During an accident sometimes a series of collision happens because the driver of the following car cannot recognize the mishap and take a right decision within a few moments. Traffic congestion on the other hand is a huge trouble which also takes place just after the accident. Vehicles in the accident area get congested, moreover without knowing about the accident, vehicles coming from the other roads make the situation knotty. This affects busy life schedule of human. So keeping those problems in mind, this paper proposes an approach that will be able to avoid series of collision and also can control traffic jam using vehicular Ad-Hoc network (VANETs), which is a network that uses car as mobile node and turns every car into a wireless router or node. We evaluate the performance of routing protocols on the basis of different parameters for different data rates using network simulator 2. Results are then analyzed on these parameters to find the suitable routing and MAC protocol for our approach in vehicular area networks.
