Li-Fi Based Handoff Technique in VANET

An adhoc network comprising of an assembly of vehicles irrespective of it being stationary or mobile constitutes Vehicular ad hoc networks (VANET). Traditionally VANET has been exploited for safety of drivers and pedestrians on the road, but now is been also utilized as an infrastructure for intelligent transport systems(ITS).Communication in VANET has always led to frequent handoffs as it is dependent on the vehicular speed along with the number of road side units(RSU)present and the available bandwidth range. These frequent handoffs may affect the throughput, packet delivery and quality of services (QoS). This paper presents detailed taxonomy of different handover processes in VANET and has laid down a comparative study based on their characteristics and features. A scheme has been presented in this paper on Light Fidelity (Li-Fi) based handover scheme involving decision making qualities. The simulation results for the proposed scheme has also been put forward and compared with a state of art hybrid works.
