Abstract EN
Vehicular Ad Hoc Networks (VANETs) are getting more popularity due to the potential Intelligent Transport Systems (ITS) technology.
It provides many efficient network services such as safety warnings (collision warning), entertainment (video and voice), maps based guidance, and emergency information.
VANETs most commonly use Road Side Units (RSUs) and Vehicle-to-Vehicle (V2V) referred to as Vehicle-to-Infrastructure (V2I) mode for data accessing.
IEEE 802.11p standard which was originally designed for Wireless Local Area Networks (WLANs) is modified to address such type of communication.
However, IEEE 802.11p uses Distributed Coordination Function (DCF) for communication between wireless nodes.
Therefore, it does not perform well for high mobility networks such as VANETs.
Moreover, in RSU mode timely provision of data/services under high density of vehicles is challenging.
In this paper, we propose a RSU-based efficient channel access scheme for VANETs under high traffic and mobility.
In the proposed scheme, the contention window is dynamically varied according to the times (deadlines) the vehicles are going to leave the RSU range.
The vehicles with shorter time deadlines are served first and vice versa.
Simulation is performed by using the Network Simulator (NS-3) v.
3.6.
The simulation results show that the proposed scheme performs better in terms of throughput, backoff rate, RSU response time, and fairness.
