Photonics-Driven V2V Link Enhancement for Accident Prevention in VANETs
Abstract
Vehicular Ad-hoc Networks (VANETs) is an important component when it comes to transmitting safety messages to avoid accidents. Nevertheless, the traditional radiofrequency (RF) vehicle-to-vehicle (V2V) communication is limited by congestion, interference, and latency during the case of heavy traffic. The given paper suggests the photonics-based improvement of the V2V link framework, which will involve the use of optical wireless communication, which may be visible light communication (VLC) and infrared (IR) links, in addition to the RF-enabled VANETs. An optical channel physical-layer model is obtained and integrated with a hybrid MC approach to prioritizing packets that pertain to safety. The outcomes of the simulations prove that the suggested design can enhance the ratio of packet delivery by a considerable amount, decrease end-to-end latency, and distribute accidental warnings faster than RF-only systems.
