A Survey and Challenges in Routing and Data Dissemination in Vehicular Ad-hoc Networks (original) (raw)

Mapcast: A map-constrained broadcast solution for VANETs

2010 IEEE 6th International Conference on Wireless and Mobile Computing, Networking and Communications, 2010

Solutions for Vehicular Ad-Hoc Network (VANET) are challenging due to the intrinsic nature of the network which involves, by definition, node mobility, scarce or null fixed nodes and, at the current state of art, lack of solutions for the real-time tracking of positions. Moreover VANETs are meant to provide primarily a solution for the improvement of road safety, by the proper forwarding of messages: this makes the overall service scenario even more critical due to the delay-constraints and the scalability issues.

Position-based Data Dissemination to Interested Region in VANETs

International Journal of Grid and Distributed Computing

Vehicular Ad-hoc Networks (VANETs) are expected to provide assistance to various applications, such as accident broadcast or emergency notification. Some kinds of applications need data to be delivered in a certain region by geocast, which means disseminating information in a specific area, instead of using a certain IP address. In this paper, we propose a data dissemination protocol for VANETs, which delivers data to all the vehicles in an interested region. We assume each vehicle is equipped with GPS and DSRC devices. Our simulation results show that this data dissemination protocol can contribute to high delivery ratio. Also, it performs well in adaptability during heavy traffic.

VANETs Networks Vehicular networks represent a fast emerging class of the MANETs

2016

Vehicular Ad-hoc Networks (VANETs) are known as a special type of Mobile Ad-hoc Networks (MANETs) specialized in vehicular communications. These networks are based on smart vehicles and basestations, which share data by means of wireless communications. To route these information, a routing protocol is required. Since the VANETs have a particular network features as rapidly changeable topology, designing an efficient routing scheme is a very hard task. In this paper, we mainly focus on surveying new routing protocols dedicated to VANETs. We present unicast, multicast and broadcast protocols. The experimental results are discussed to evaluate the performance of the presented methods. Key-words: Vehicular Ad-hoc networks, Routing, Unicasting, Multicasting, Broadcasting.

VEHICULAR AD-HOC NETWORK: VANET

Vehicular Ad-hoc Networks, (VANET) are a particular kind of Mobile Ad Hoc Network, (MANET), in which vehicles act as nodes and each vehicle is equipped with transmission capabilities which are interconnected to form a network. The topology created by vehicles is usually very dynamic and significantly non-uniformly distributed and this technique is also known as Intelligent Transportation System (ITS).VANETs is a kind of special wireless ad hoc network .VANET has become an active area of research, standardization, and development because it has tremendous potential to improve vehicle and road safety, traffic efficiency and convenience as well as comfort to both drivers and passengers .The aim of this review paper is to give an overview of the vehicular ad hoc networks, its characteristics , the existing VANET routing protocol, Security and privacy, applications.

Evaluating Information Dissemination Approaches in VANETs

2010

Vehicular Ad-hoc Networks (VANETs) appeared as a subclass of MANETs for inter-vehicle communication. VANETs have relatively more dynamic nature as compared to MANETs with respect to network topology. However, among numerous solvable issues in VANETs, the design and implementation of an efficient and scalable architecture for information dissemination constitutes one major issue. In the past few years, several broadcasting protocols for information dissemination are proposed specifically in the context of MANETs. In this paper, we will first elaborate some differentiable characteristics of VANETs and then will present a performance analysis of these broadcasting protocols in VANETs environment.

A Novel VANET Data Dissemination Approach Based on Geospatial Data

Procedia Computer Science, 2016

The main objective of VANET networks is to improve road safety as well as transportation efficiency through the use of wireless communications technologies and the emergence of low cost embedded sensors. Thus, the design of an efficient data dissemination protocol, that informs vehicles about interesting safety events, is of paramount importance. The thriving challenge would be to maximize the delivery ratio by avoiding as far as possible the broadcast storm problem. A scrutiny of the literature wealthy number of approaches highlights that all of them fail to fulfill with a critical requirements. In this paper and to palliate this shortage, we introduce a new infrastructure-less Geocast protocol that send messages only to vehicles in the Zone of Relevance (ZOR) with a minimum overhead cost. Our protocol stands in reaching a high delivery ratio as well as a high Geocast precision by only sending messages to vehicles in the Zone of Relevance (ZOR) with a minimum overhead cost. Carried out experiments show that our protocol outperforms its competitors in terms of effectiveness and efficiency.

International Journal of Advanced Science and Technology, 2020

Vehicles ad hoc networks (VANETs) have arisen as an interesting area of study and implementation. To ensure smart connectivity for vehicle networks, VANETs may enhance the reliability and productivity of road traffic exceptionally. A distribution of data in the VANET system is an extremely difficult challenge because of fast adjustments and recurrent fragmentation of the network.in this paper, we survey on explain this review on three parts. In the first part, we will show the concept of data dissemination and explain all their types. in the second part, we will provide a comprehensive review on kinds of routing protocols, finally, the third part, we will discuss some of the issues and challenges.

Cross-network information dissemination in VANETs

2011

In this work, we provide an overview of an innovative approach for effective cross-network information dissemination, with applications to Vehicular Ad-hoc Networks (VANETs). In particular, we describe the main approach followed in an on-going bilateral Italy-Israel project ("Cross-Network Effective Traffic Alert Dissemination," X-NETAD). The X-NETAD project leverages on the spontaneous formation of WiFi local VANETs, with direct connections between neighboring vehicles, in order to disseminate, very quickly and inexpensively, traffic alerts received from the UMTS network.
