Vehicular Ad Hoc Networks (VANET) are the fastchanging networks for connected vehicles, in which Vehicle- to-Vehicle and Vehicle-to-Infrastructure communication are the basis for technologies aiming at reducing accidents and improving operation. DSRC Safety Applications, designed to assist drivers in order to avoid accidents, might be subjected to malicious attacks, such as GPS time spoofing attacks,...
The traffic control system proposed in this article has as its main objectives the security, the reliability and the anonymity of the vehicle access to traffic-restricted urban zones. The aim of these zones is to reduce atmospheric pollution in urban centers. The presented approach makes use of smartphones as a communication device between the user and the virtual barrier, which acts as electronic...
Vehicle traffic on highway systems is typically not uniformly distributed. In this paper, we introduce a protocol that exploits this phenomenon by considering the formations of shock waves and opportunities in adjacent lanes. The objective of this protocol is to reduce the impact of a shock wave by using event-driven messages between vehicles that provide drivers with velocity or lane switching recommendations...
Drivers change the lane over the road networks is a common seen practice when they face a slow, stopped or broken vehicle. Sometimes they have to change the lane to take the next exist or the next U-turn towards their targeted destination. Changing the lane requires that the driver should be aware of vehicles behind him on the new lane or vehicles intending to change to the same lane during that period...
The overloaded transportation networks in big modern cities have always been a severe issue, resulting in congestion, environmental pollution, waste of energy, and of people's time and money. In this paper, we will discuss the potential solutions that could be offered by the utilization of a flexible ridesharing system. We will discuss the current standings of existing ridesharing tools and then propose...
In this paper, we propose an in-vehicle cloudlet computing disaster information system that can flexibly deal with critical network connectivity. In order to achieve this purpose, we develop a dynamic allocation of server resources in accordance with the load change on the system so that it is possible to take full advantage of in-vehicle server and network resources in the disaster areas. Also, by...
Vehicular Ad hoc Networks (VANETs) are an important component of the advanced information networking for inter-operable communications with a wide range of networks. In our previous work, we proposed a method of Enhanced Message Suppression Controller (EMSC) considering delayed ack for vehicular Delay/Disruption Tolerant Networking (DTN). In this paper, we evaluate the performance of our proposed...
New advanced traffic management solutions with fully or semi-autonomous vehicles that communicate over a wireless interface to coordinate their driving decisions create new challenges in distributed computing. In this paper we address the problem of dynamic group membership in three stages. First, we propose three criteria to specify correctness and performance of the group views created by such algorithms...
To reduce the amount of CO2 produced from the personal cars in the world, the parking lot guidance systems are considered to be the solution in shopping malls or department stores in many countries. However, most of the current parking lot systems are located in the parking area of each shopping mall and they cannot show the parking lots information for the driver that are driving on the road. So,...
Vehicle-to-vehicle communication systems support diverse cooperative applications such as virtual traffic lights. However, in order to harness the potential benefits of those applications, one must address the challenges faced by distributed algorithms in environments based on unreliable wireless communications. In this paper we address the problem of leader election among the nodes of a cooperative...
In this paper we consider systems consisting of a number of spatially invariant, i.e., identical, subsystems that use packet-based communication networks for the exchange of information. Recent literature has shown that for an infinite number of such interconnected networked subsystems, the overall system can be modeled as an infinite interconnection of identical hybrid (sub)systems. Based on this...
A Vehicular Cloud generally focuses on several aspects, which include providing a set of computational services at low cost to vehicle drivers; minimizing traffic congestion, accidents, travel time, and environmental pollution; and ensuring the use of low energy and real-time services of software, platforms, and infrastructure with QoS to drivers. The largest challenge in vehicular mobile Clouds consists...
Vehicular Ad-hoc Networks (VANETs) technology has been utilized in recent applications to enhance the traffic fluency over the road network. Various types of emergency cases may negatively affect the efficiency of traffic flow in highway road scenarios, including accidents, damaged vehicles or the presence of emergency vehicles. These cases exaggerate...
Vehicles are increasingly wirelessly connected and each wireless connection is a potential cyber threat surface. Many of these wireless communications are related to the infotainment systems and are optional, some are not. Since 2008, when the U.S. government mandated the need for real-time tire pressure diagnostics, automotive manufacturers have inserted Tire Pressure Monitoring System (TPMS)-based...
Internet of Vehicles requires reliable Inter-Vehicular communications. Such a requirement is challenging since the wireless communication channel is very erroneous and lossy in city environments. A lot of solutions for connecting vehicles to the internet have been proposed. However, existing multi-hop gateway discovery solutions do not consider, a key issue, the unreliability of broadcast in city...
Collaborative Intelligent Transportation Systems are almost part of our everyday life. A C-ITS environment can provide numerous services that soon will become essential to roads' users. The latter resides in improvement of road safety, entertainment, and commercial services. However to provide such services, the C-ITS environment needs an advertisement and dissemination service of the latter. Indeed,...
Software systems for robotics increasingly require support for robust interprocess communication with common interfaces, which has given rise to the use of “middleware” software projects. However, autonomous underwater vehicles (AUVs) have a significantly different intervehicle communication regime than other branches of robotics due to the physical realities of the ocean as a communication medium...
With the number of Electric Vehicles (EVs) increasing, there is a growing need to schedule the charging of EVs in order to optimize grid load and improve stability. Charging scheduling involves several communications between the EV and the charging station (state of charge and time of arrival) happening either immediately before charging or at some earlier point in time. On account of privacy concerns...
In the near future, beacon dissemination base stations will be deployed in shopping mall, supermarkets, stadiums, museums, and theatres to send advertisements offering services and products to the customers with mobile devices. Today, an example of this concept of business model is the Apple's iBeacon. Borrowing this concept from mobile computing, we envision a new opportunity for business modeling...
A distributed network of vehicles well-known as Vehicular Ad Hoc Networks (VANETs) has created a new communication paradigm, which enables us to exploit the mobility of vehicles for data dissemination process within a geographical area of interest. Several data dissemination protocols have focused on two main problems in VANETs: broadcast storm and disconnected network. Moreover, the most of data...
