Survey on Collision Avoidance in VANET

Abstract

VANET is an emerging technology to achieve intelligent intervehicle transmission and result if VANET. It Mostly resembles criteria remain same. The speed and choice of the path describe the dynamic topology [2] of VANET. If we assume two vehicles moving away from each other with a speed of 60 mph. Some of the well known ad hoc routing protocol such as AODV (Ad Hoc on demand distance vector) and DSR (Dynamic source routing) are therefore can be applied to VANET as well. VANET provides a wide range of applications like safety of vehicles on roads, driver assistance, sharing traffic and determining road conditions for smooth flow of traffic. In this paper various systems using collision avoidance [8] and provides the road safety using ITS (Intersection collision avoidance), CWAS (collision warning avoidance system), and the most appropriate simulation tools to simulate VANET protocol and applications). VANET has the tremendous challenges in roadside areas because VANET having the potential to avoid the traffic accidents and having efficiency. Recent research have been placed the VANET design architectures and implementations. Nowadays VANET research work have been focuses on the including areas like routing, broadcasting, Quality of Service (QoS), and security. We survey some of the research results in these areas.

Accident Prediction System Based on Hidden Markov Model for Vehicular Ad-Hoc Network in Urban Environments

“…Many APSs have been proposed in the last few years. The works in [9][10][11] surveyed the recent techniques in the literature of collision prediction and avoidance using VANET. However, most of the state-of-the-art schemes are based only on the vehicle's velocity, or another factor solely.…”

“…Using γ t (i) and ε t (i, j), the parameters λ(π, A, B) were updated every time we parsed a new element from O; we denoted the updated parameters as λ(π * , A * , B * ), see (8), (9) and (10):…”

When Backscatter Communication Meets Vehicular Networks: Boosting Crosswalk Awareness

“…pedestrians, bicyclists, and motorcyclists, must not be neglected from these systems. Active collision protection systems with emergency braking and collision mitigation capabilities, despite the technical challenge they represent, can be considered indispensable, to truly decrease traffic-related fatalities [5], [6]. Nevertheless, the success of such services depends not only on the platform used to collect and process the accurate data from the environment, but also on the communication infrastructure.…”
