This paper proposes an extension of IPv6 neighbor discovery (ND) for rapid network prefix and service discovery in vehicular networks. It is assumed that a vehicle as a moving network (MN) or a road-side unit (RSU) as a fixed network (FN) has an external network interface, and hosts in an MN periodically announce their services to their local DNS Server called recursive DNS server (RDNSS) of the MN...
In this study, we propose a variation of the RAdNet for vehicular environments (RAdNet-VE). The proposed scheme extends the message header, mechanism for registering interest, and message forwarding mechanism of RAdNet. Based on results obtained from simulation experiments, we compare the performance of RAdNet-VE against that of RAdNet, a basic content-centric network (CCN) using reactive data routing,...
In this paper, we describe an VM2M overlay architecture where the overlay acts as the control channel (CCH) of VANET to transfer safety messages between vehicles and RSU. The VM2M overlay network is implemented over dedicated preamble codes in the physical layer and the medium access control (MAC) layer modeled as the IEEE 802.15.4 carrier sense multiple access (CSMA/CA) mechanism. In this paper,...
Multi-hop broadcast communication is one of the main communication mechanisms to propagate safety and non-safety messages through vehicles in Vehicular Ad hoc Networks (VANETs). In our previous work, we proposed two broadcast schemes, fuzzy logic-based broadcast (FLB) and bandwidth-efficient fuzzy logic-assisted broadcast (BEFLAB). FLB offers high level of reachability where BEFLAB is more bandwidth...
In vehicular ad-hoc network (VANET), safety applications require the dissemination of safety information and vehicular states to all nearby vehicles through broadcasting. However, due to the tremendous information, broadcast channel will be confronted with great pressure. Therefore, vehicles should adjust their contention window to avoid intense competition on channel. In this paper, we propose a...
In vehicular ad hoc network (VANET), vehicles are connected in a self-organized manner to collect and share various traffic data about the road condition, accidents, traffic congestions, and other related events, This data can be used to improve the driving quality, however VANET vehicles may receive unreliable data broadcasted by malicious vehicles which may result in unsafe driving and accidents...
Intelligent Transportation Systems (ITS) use Vehicular Ad Hoc Network (VANET) for safety applications aiming to reduce traffic accidents. The applications, which use Dedicated Short Range Communications (DSRC) with the IEEE 802.11p Medium Access Control (MAC) protocol are exposed to the full range of security problems associated with wireless technology, including wireless jamming. This research introduces...
Intelligent Transportation System (ITS), the safety-related message is propagated based on the wireless communications through vehicle to vehicle (V2V) and vehicle to infrastructures (V2I) in vehicular Ad hoc networks (VANETs) environments. Hence, the network connectivity is a key requirement for successfully safety-related message propagation. In this paper, we analyze the influence of vehicle density...
The paper presents a solution for reducing road traffic emissions and particulate matter from non-electric (classic) vehicles in cities by sharing cooperative driving information. Vehicles are equipped with dynamics and GPS sensors. Ad-hoc vehicular networking (VANET) is used as media for communication. A specific algorithm is developed to collect anonymous information and suggest to drivers best...
Recent years, Vehicular ad hoc Network (VANET) attracts tremendous attention due to its broad application prospects. However, channel fading, frangible link, unstable network topology caused by vehicles' high mobility and strict requirements to the quality of service (QoS) have become major challenges of VANET. Many algorithms have been proposed to ensure a stable network topology and it has been...
Cooperative Intelligent Transportation Systems (CITS) are being developed to make road traffic safer and more efficient. Vehicle to vehicle (V2V) communication plays an important role for the cooperative awareness of vehicles in all the CITS standards in EU, US, and Japan. Essentially the CITS application relies on the exchanged data by V2V messages (called Cooperative Awareness Message (CAM) in EU)...
The VANET (Vehicular Ad hoc Network) is a collection of mobile nodes forming a temporary network on variable topology, operating without base station and without centralized administration. The characteristics of VANET network that distinguishes it from other ad hoc networks, such as high mobility and communication with the infrastructure to support security or comfort applications, have prompted...
Conceiving a smart city is coming to maturity, to make less the problems produced by the swift urbanization. It mainly focuses on how to increase the quality and comfort of citizens by using information and communication technologies. That being said, make smart cities will offer a flamboyant metamorphosis for the success of cities' development, they propose a way adapted to the multitude of urban...
The paper proposes a method to make roads a safer place for driving by taking advantage of Internet of Things (IoT) enabled vehicles. The proposed method is based on assessing the trust levels of each vehicle and the behavioral patterns of the driver. Proposed method also utilizes a mobile agent(MA) which would help detecting Misbehaving nodes in the IoT enabled Vehicular Adhoc NETwork (VANET). The...
Vehicular Cloud Computing (VCC) is the latest technology in intelligent transport system. Vehicular cloud (VC) facilitates the customers to share underutilized resources by renting it to other users over the Internet. It aims to improve travelling beyond the boundaries of traditional transport systems. VCC has many advanced applications which will help society with minimum cost of investment and less...
Numerous efforts are currently under progress to enhance the safety and efficiency of vehicular traffic through intelligent transportation systems. In addition, the growing demand for access to data and information from human users on the go has created the need for advanced vehicle-to-vehicle and vehicle to roadside communication systems capable of high data rates and amenable to high degrees of...
Recent advancements introduced in the field of wireless technologies have led to the emergence of vehicular ad hoc networks (VANETs). VANET consists of vehicles and road-side units as its components. These components communicate with each other to share the information, mainly related to traffic conditions. In such networks, routing, secure transmission of control information and user messages, avoiding...
Routing is considered as one of the most important processes in computer networks especially ad hoc networks. Vehicular ad hoc networks require to use efficient protocols for routing in order to exchange data between network nodes for various reasons including lack of infrastructure in some circumstances, high mobility of nodes, network dynamics and lack of trusted nodes. Because of the need for security...
The Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) is an integrated algorithm employed in the Enhanced Distributed Channel Access (EDCA) in the IEEE 802.11p protocol. CSMA/CA manages the access of packets to the medium and its main role is to avoid collisions among them. An essential process of CSMA/CA is the backoff period in which the packets has to wait for a random number of...
