An Efficient Approach towards Vehicle Number Estimation with Ad-hoc Network under Vehicular Environment

Ad-hoc network usability extends the application for Dedicated Short-Range Communication. This type of ad-hoc network technology is non infrastructure and due to this fact, it can be used for Direct Short Range Communication System to provide the quick and real time message to the vehicular operator to prevent the damage and fatality of life by meeting accidents and crashes. In this paper, we present a holistic approach to estimate the number of vehicles in specified range of one KM distance. The designed system for vehicle number estimation is based on the Time Division Multiple Access mechanism which further estimates the number of reserved slots by vehicular nodes. This estimation methodology is tested under the digital simulator and approximately 34 number of vehicles for 24 seconds are defined to test the slot reservation. We found that in case of vehicular nodes greater than 20, slot reservation accuracy is 95% and when the vehicular nodes are less than 20 then the slot reservation is 100%.
