VANET Simulators: A Survey on Mobility and Routing Protocols

Abstract

Vehicular Ad-hoc Networks (VANETs) are an instance of Ad-hoc networks, which are general-purpose distributed wireless networks interconnected without the need of any centralized infrastructure. VANETs are expected to be massively deployed in upcoming vehicles, because their use can improve the safety of driving and makes new forms of inter-vehicle communications possible as well. The simulation of VANETs requires two different components: a vehicular traffic simulator, capable to provide an accurate mobility model for the nodes of a VANET, and a network simulator, for simulating the behavior of a wireless network. In this paper, we provide a survey of mobility models proposed for VANETs. We analyze challenges and future perspectives of VANET simulators and current routing solutions for VANET.

Enhancing broadcast vehicular communications using beamforming technique

“…In order to remediate to the deficiencies of probabilitybased protocols, position-based routing protocols [3] were introduced. They assume that each vehicle is aware of the positions of other vehicles in order to select its one hop neighbor that ensures the communication between the nodes even in high mobility scenarios.…”

Opportunistic Delayed Transmission for Network Coding in Vehicular Wireless Networks

“…IEEE stipulated the IEEE802.11p [1] standard and Wireless Access in the Vehicular Environment (WAVE). In VANET [2], mobile nodes usually move at a high speed. Thus, the network topology changes frequently.…”

A Machine Learning System for Routing Decision-Making in Urban Vehicular Ad Hoc Networks

“…Many routing protocols have already been proposed such that data can be transmitted more efficiently. Routing protocols can be classified into the five categories detailed below [1][2][3][4][5][6][7][8][9][10]. First, topology-based routing protocols use link information that exists in the network in order to find the best route on which to forward packets.…”
