VANETs Networking Protocols : An Analytical study
The Tenth International Conference on Sensor Technologies and Applications ( SENSORCOMM 2016), 2016
Résumé
Vehicular Ad hoc NETworks (VANETs) are considered as a class of Mobile Ad hoc NETworks (MANETs). The VANETs are a set of vehicles that are capable of exchanging data dynamically and without needing any pre-existing and fixed network infrastructure. Each node sends and receives messages in its communication area. Thus, message routing is done through a routing protocol. Despite the fact that the VANETs are a subgroup of the MANETs, they possess exceptional network behaviors like high mobility and dynamic topology, which make the MANETs routing protocols unsuitable for the VANETs. This paper summarizes the different protocols used for routing in the VANETs that focuses on a vehicle-to-vehicle communication. Utilizing an OMNET++ simulator, the experimental results are discussed to compare the presented routing protocol categories.

The 7th International Conference on Emerging Ubiquitous Systems and Pervasive Networks (Elsevier, EUSPN-2016), 2016
Résumé
The Vehicular ad -hoc networks (VANETs) are a specific type of Mobile ad-hoc networks (MANETs). However, the main problem related to it is the potential high speed of moving vehicles. This special property causes frequent changing in network topology and instability of communication routes. Consequently, some of the challenges that researchers focus on are routing protocols for VANETs. They have proved that the existing MANET proactive routing protocols are the most used for vehicular communication. Yet, they are not as adequate as they are for VANETs. The main problem with these protocols in dynamic environment is their route instability. This paper combines multi-agent system approach and PSO algorithm to solve the above mentioned problems. We carried out a set of simulations tests to evaluate the performance of our scheme. The simulation part shows promising results regarding the adoption of the proposed scheme.

International conference on Big Data and Advanced Wireless technologies (ACM,BDAW 2016) ,, 2016
Résumé
The key difference of Vehicular Ad- hoc Network (VANET) and Mobile Ad-hoc Network (MANET) is the exceptional mobility pattern and quick variability variable of network topology. The existing MANET routing protocols are inadequate for the VANET. One good manner of data sending in vehicular environment is to enhance the MANET routing protocols and make them appropriate for the VANET. Ad-hoc On-demand Distance Vector (AODV) is one of the most important MANET reactive protocols. Nevertheless, once we have to deal with a VANET, its performance is poor. In this paper, we propose an enhancing the AODV routing protocol based on agent technology to improve the Quality of Service (QoS) in VANET. The experimental results show that our approach outperforms the AODV protocol in terms of routing overhead, dropped packets rate and transfer packets delay.

A multi-agent proactive routing protocol for Vehicular Ad-Hoc Networks
Proc.of The 2014 International Symposium on Networks, Computers and Communications (IEEE ISNCC 2014),, 2014
Résumé
Vehicular ad hoc network is one of the most promising applications of MANET. However, they have special properties such as high mobility, network portioning and constrained topology which require smaller latency and higher reliability. These vehicles that move along the same road are able to communicate either directly to the destination or by using the intermediate node, such as router. Therefore, designing an efficient routing protocol for all VANETs scenarios is very hard. A lot of researches about routing in VANETs are considering DSDV routing protocol as the most suitable protocol for mobility environment. But DSDV generates a large volume of control packets and takes up a large part of available bandwidth. In this paper, we propose an improving DSDV routing protocol based on multi-agent system approach to solve the performance problems mentioned above. Experimental results show promising results regarding the adoption of the proposed approach.

A Multi-agent Approach for Routing on Vehicular Ad-Hoc Networks,
The 4th International Conference on Ambient Systems, Networks and Technologies, 2013
Résumé
Vehicular Ad-Hoc Network is a special form of mobile ad -hoc networks (MANETs) which is a vehicle to vehicle and vehicle roadside wireless communication network. VANET is a new standard that integrates Wi-Fi, Bluetooth and other mobile connectivity protocols. The essential requirement of VANET is that it should be able to communicate in any environment irrespective of traffic densities and vehicle locations. Vehicular communications are made in fluctuating environment and should work both in urban and rural areas. Considering the large number of nodes participating in these networks and their high mobility, debates still exist about the feasibility of routing protocols. Analyzes of traditional routing protocols for MANETs demonstrated that their performance is poor in VANETs. The main problem with these protocols in VANETs environments is their route instability. Consequently, many packets are dropped and the overhead due to route repairs or failure notifications increases significantly, leading to low delivery ratios and high transmission delays. This paper introduces a multi-agent system approach to solve the problems mentioned above and improve Vehicular ad-hoc network routing.
