Comparative review on optimizing headway distance for connectivity in vanets using artificial bee colony algorithm

摘要

In vehicular adhoc networks abbreviated as VANETS vehicles are furnished with radio devices which qualify them to interchange traffic information without the requirement of any kind of infrastructure [3-6]. However the understanding of vehicle headway distribution is crucial for evaluating the probable range of connectivity in these vehicle ad hoc networks. Several studies on dissemination of vehicles in a single lane had taken into account the minimum safe distance to be maintained between consecutive vehicles. The account of this safe distance improves the agreement between vehicles conceptual spacing distribution and factual data in single lane traffic. Although the account of this minimum headway distance based VANETs has shown better results than other techniques but it still suffers from the effects of abnormal environmental conditions on traffic. So in order to remove these issues, a new technique is proposed. The proposed technique will use dynamic communication and dynamic path selection using artificial bee colony algorithm to enhance the results of VANETs further. Also the proposed technique is evaluated and compared with existing techniques on the basis of the parameters which include connectivity probability, end to end delay, throughput and overheads.
