“…Hence, in the rest of this paper we only consider the use of ad hoc communications between vehicles. Moreover, new short-range communication protocols dedicated for vehicular applications are under standardization, such as the Wireless Access in Vehicular Environments (WAVE) protocol [13]. They will provide vehicles and pedestrians the ability to communicate with each other and with the road-side infrastructure with a bandwidth up to 27 Mbps.…”

Abstract-A vehicular ad hoc network (VANET) is a type of mobile network whose nodes are traveling cars and which communicate with one another using short-range wireless communications. These cars can exchange and share different information among them, which can lead to the development of interesting applications that require the cooperation of vehicles or using the vehicular network as a distributed computing platform. Along with the opportunities offered by vehicular networks, a number of challenges also arise.In this paper, we focus on information gathering in vehicular ad hoc networks. Until now, only a few research works have addressed this problem. They have lead to solutions relying on push models, where potentially useful data are pushed towards vehicles. To the best of our knowledge, no work has tackled the use of pull models in VANETs. Such models would allow users to send queries to a set of cars in order to find the desired information. In order to propose such a query processing scheme, the main challenge to address is to route the different results towards their recipient in a highly dynamic network where the nodes move very quickly. To solve this issue, we propose GeoVanet, a DHT-based geographic routing protocol which ensures that the sender of a query can get a consistent answer. Our goal is not to compute the query result "instantaneously" but to ensure that the user will be able to retrieve it within a bounded time. To prove the effectiveness of GeoVanet, an experimental evaluation is provided in the paper. It shows that up to 80% of the available query results are delivered to the user.

“…This approach is the same implemented by ND to deal with different Source/Target Link-layer Address (Narten et al, 2007). Nevertheless, the use of a different MAC address format seems unlikely because WAVE architecture only supports IEEE MAC 802.11p (Morgan, 2010). In this work we encapsulate only the MAC address into the MAC field of signalling messages.…”

The interest in vehicular communications has increased notably. In this paper, the use of the address resolution (AR) procedures is studied for vehicular ad hoc networks (VANETs). We analyse the poor performance of AR transactions in such networks and we present a new proposal called coherent, automatic address resolution (CAAR). Our approach inhibits the use of AR transactions and instead increases the usefulness of routing signalling to automatically match the IP and MAC addresses. Through extensive simulations in realistic VANET scenarios using the Estinet simulator, we compare our proposal CAAR to classical AR and to another of our proposals that enhances AR for mobile wireless networks, called AR+. In addition, we present a performance evaluation of the behaviour of CAAR, AR and AR+ with unicast traffic of a reporting service for VANETs. Results show that CAAR outperforms the other two solutions in terms of packet losses and furthermore, it does not introduce additional overhead.

“…One of the specifications of IEEE 802.11p is that the management functions are connected with the physical and MAC layers which are called physical layer management entity (PLME) and MAC layer management entity (MLME), respectively [29]. The IEEE 802.11p uses CSMA/CA to reduce collisions and provide fair access to the channel.…”

VANETS are considered as one of the most prominent technologies for improving the efficiency and safety of modern transportation systems. A VANET will be a major contribution toward the realization of Intelligent Transportation Systems. The main aim of VANET ranges from improved road safety, time critical safety applications, optimized traffic flow, delay tolerant, and infotainment and so on. High relative nodes pace and high active nodes mass has offered a typical challenges for connectivity within VANET. A lot of researches from the industry, academia, and standardized agencies to develop standards and prototypes for vehicular networks. In this paper, a complete survey on existing technologies in VANET is being presented. KeywordsVANET (Vehicular Adhoc NETwork), OBU (On Board Unit), RSU (Road Side Unit), AU (Application Unit), DSRC (Dedicated Short Range Communication), WAVE (Wireless Access for Vehicular Environment). INTRODUCTIONVehicles are needed for transportation. People drive cars so that they can have the freedom they need to be able to get where they need to go when they need to get there. Due this reason number of vehicles is increased. The increase in vehicles leads to lot of mishaps on the road which can happen in highway or city areas. To overcome these catastrophes a good communication network need to be built between the vehicles. This leads to a new advance technology Vehicular Adhoc NETwork (VANET). VANET is one of the sub branches of MANET technology. In Mobile Adhoc NETwork (MANET) each mobile is considered as node whereas in VANET each vehicle is considered as a node. These days, an immense number of auto organizations are conveying vehicles with in-auto sensors, installed figuring and remote specialized gadgets, and navigation systems (e.g., GPS) in preparation for the use of large-scale vehicular networks. By using different sensors, cameras and communication competence, vehicles can gather and interpret information with the intention of helping the driver to make a judgment, particularly in driver support systems. Fig 1 gives the comparison between MANET and VANET. The nodes in MANET and VANET are self-composed, selfguided specially ad hoc network and decentralized in a distributed manner with a self observed authority or a server to direct the communication. Nodes themselves go about as servers and/or clients by exchanging and sharing data like peers. Even though VANET is a subpart of MANET, there are lot of difference in the characteristics of MANET and VANET. The MANET can contain many nodes that have uncontrolled moving prototypes. But since VANET is created generally by vehicles so node movement is limited by factors like road lane, traffic and traffic regulations. MANET vs VANET MANET Characteristics and Applications MANET CharacteristicsDistributed operation: For the central control of the network operations, thusly there is no backgrounds arrange rather the control of the network is conveyed among the nodes. The nodes included in a MANET ought to coordinate with one anoth...
