In the recent decade the VANET has been emerged as a prominent field for research and it receives considerable attention. VANET uses different specifications of the WLAN 802.11 family. It takes the basics of ad hoc network and the VANET creates a network with a collection of independent entities with the ability to communicate among themselves. The Adaption to the various 802.1 family causes a remarkable...
In wired networks there are different physical devices routing the traffic centrally. By consequence, we can create paths in the network by using multiple management rules, but in Ad-Hoc network nodes this work must be done in an autonomous way. For that there are three types of routing protocol proactive, reactive and hybrid. The first one continuously calculates the possible paths to be available...
One of the notoriously difficult problems in vehicular ad-hoc networks (VANET) is to ensure that established routing paths do not break before the end of data transmission. This is a difficult problem because the network topology is constantly changing and the wireless communication links are inherently unstable, due to high node mobility. In this paper we classify existing VANET routing protocols...
Location information is very important for many applications of vehicular networks such as routing, network management and safety. However, the mobility of vehicle usually results in many location errors. To solve the problem, various prediction schemes have been proposed. In the paper, by Rough sets theory, a novel location prediction technique LPVN that incorporates the vehicle position information,...
A vehicular network is a promising application of mobile ad hoc networks. In this paper, we introduce a near-optimal broadcast technique, called CB-S (Cell Broadcast for Streets), for vehicular networks. In this environment, the road network is fragmented into cells such that nodes in a cell can communicate with any node within a two cell distance. Each mobile node is equipped with a GPS (Global Positioning...
A vehicular ad hoc network (VANET) is a highly mobile wireless ad hoc network that is targeted to support vehicular safety, traffic monitoring, and other applications. Mobility models used in traditional mobile ad hoc networks cannot directly be applied to VANETs since real-world factors such as road layouts and traffic regulations are not considered. In this paper, we propose a vehicular mobility...
The idea of store-carry-forward has been introduced for using in sparse vehicular ad-hoc networks (VANETs) in order to answer the problems of VANET as a highly mobile partitioned ad-hoc network; however, there has not been a deep analytical discussion on performance of store-carry-forward in different situations of vehicular network. In this paper, a Markov chain model for urban mobility is proposed...
MANET marks the new age of the modern communication and it is a key technology to solve many applications such as telemedicine, environment monitoring, intelligent transport system (inter-vehicle communication) etc. In this paper a new MANET protocol dedicated to intelligent transport system: CIVIC (communication inter vehicule intelligente et cooperative) is described. CIVIC is a context aware routing...
VANET is a special case of MANET, and will play an important role in city road traffic control. The application of VANET to city road traffic control was studied. The feasibility of VANET was justified, the city section mobility model was appended in NS2, the network model of VANET was established, the simulation scene was compiled, the performances of DSDV, DSR, two classical routing protocols of...
