Abstract:Information sharing among emergent issue in Vehicular Ad H (VANETs). Considering the mobility connectivity of the nodes in a typical VAN scalable schemes for information sharing In this paper, we propose a distribute (P2P) based architecture for informat VANETs. We split the entire vehicular geographically unique zones and use con techniques to map the nodes and the unique identifiers in Distributed Hash hence providing scalable look-up serv work aims to develop scalable rou replication and handover managemen … Show more
“…N. Dutta [150] design a new DHT based p2p technique, this technique divides the map into many zones and each zone has a zip code, each zone and each file is hashed in a ring (i.e., SHA-1). Each file is assigned by the successor zone in the ring, so If a car wants a file, it will hash the name of a file and ask the cars of the successor zone for the file.…”

“…In [12] broadcasting after specified interval is suggested to improve the data delivery rate. In [14], [11], [15] authors have worked on multi-hop network and shared information to destination node that is several hops away from source node. File sharing is also done using special protocols [16] as well as by splitting files into pieces.…”
In recent years the number of automobiles have been increased on the roads. Due to high density of vehicles, the potential threats and road accidents are increasing. Alongside new application domains are evolving such as infotainment. VANETs is an emerging technology where the information is exchanged among the vehicles on the road to provide updates about different road situations and dangerous conditions, to save time and lives. A lot of research is carried in this field and many simulations studies are available. The experimental studies based on the open sources hardware models are very rare. We have developed a prototype for VANETs to exchange short safety messages and infotainment sharing among the vehicles. Along with designing we have also analyzed its performance and obtained results by doing many experiments using Arduino.
“…It is interesting to mention that other works have proposed the use of distributed hash tables in mobile ad hoc networks and vehicular networks (e.g., [15,23]).…”

In a vehicular ad hoc network (VANET), cars can exchange information by using short-range wireless communications. Along with the opportunities offered by vehicular networks, a number of challenges also arise. In particular, most works so far have focused on a push model, where potentially useful data are pushed towards vehicles. The use of pull models, that would allow users to send queries to a set of cars in order to find the desired information, has not been studied in depth. The main challenge for pull models is the difficulty to route the different results towards the query originator in a highly dynamic network where the nodes move very quickly. To solve this issue, we propose GeoVanet, an anonymous and non-intrusive geographic routing protocol which ensures that the sender of a query can get a consistent answer. Our goal is to ensure that the user will be able to retrieve the query results within a bounded time. To prove the effectiveness of GeoVanet, an extensive experimental evaluation has been performed, that proves the interest of the proposal for both rural and urban areas. It shows that up to 80% of the available query results are delivered to the user.
