Data Traffic Forwarding for Inter-vehicular Communication in VANETs Using Stochastic Method

摘要

In recent years, vehicular ad hoc network (VANET) is an emerging technology for intelligent transportation system by providing its wireless network services to increase the demands of high data rate and traffic. VANET supports for various applications that include safety, vehicular distribution speed, traffic efficiency and information of data services. In this paper, we propose the stochastic method for multi-hop connectivity through vehicle to infrastructure and vehicle to vehicle in inter-vehicular communication system to improve the performance of the network. We have evaluated the performance analysis of the queuing system by measuring the traffic flow in highway lanes. In highway lanes, the collision between any two vehicles leads to traffic jam with heavy congestion in the highway lanes which are in the VANET system. Due to the stagnation of accumulated vehicles on the highway will further result in increasing the delay in clearance of the traffic on the road. We have evaluated the performance of the VANET system through the M/M/1 queuing model for analyzing parameters such as the end to end delay, waiting time and congestion on express highways at peak hours for multi-hop connectivity.
