VANET Applications: Hot Use Cases

Current challenges of car manufacturers are to make roads safe, to achieve free flowing traffic with few congestions, and to reduce pollution by an effective fuel use. To reach these goals, many improvements are performed in-car, but more and more approaches rely on connected cars with communication capabilities between cars, with an infrastructure, or with IoT devices. Monitoring and coordinating vehicles allow then to compute intelligent ways of transportation. Connected cars have introduced a new way of thinking cars - not only as a mean for a driver to go from A to B, but as smart cars - a user extension like the smartphone today. In this report, we introduce concepts and specific vocabulary in order to classify current innovations or ideas on the emerging topic of smart car. We present a graphical categorization showing this evolution in function of the societal evolution. Different perspectives are adopted: a vehicle-centric view, a vehicle-network view, and a user-centric view; described by simple and complex use-cases and illustrated by a list of emerging and current projects from the academic and industrial worlds. We identified an empty space in innovation between the user and his car: paradoxically even if they are both in interaction, they are separated through different application uses. Future challenge is to interlace social concerns of the user within an intelligent and efficient driving

A heterogeneous short-range communication platform for internet of vehicles

The automotive industry is rapidly accelerating toward the development of innovative industry applications that feature management capabilities for data and applications alike in cars. In this regard, more internet of vehicles solutions are emerging through advancements of various wireless medium access-control technologies and the internet of things. In the present work, we develop a short-range communication–based vehicular system to support vehicle communication and remote car control. We present a combined hardware and software testbed that is capable of controlling a vehicle’s start-up, operation and several related functionalities covering various vehicle metric data. The testbed is built from two microcontrollers, Arduino and Raspberry Pi 3, each of which individually controls certain functions to improve the overall vehicle control. The implementation of the heterogeneous communication module is based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 and IEEE 802.15 medium access control technologies. Further, a control module on a smartphone was designed and implemented for efficient management. Moreover, we study the system connectivity performance by measuring various important parameters including the coverage distance, signal strength, download speed and latency. This study covers the use of this technology setup in different geographical areas over various time spans

Feasability of Bluetooth 5.0 connectionless communications for I2V applications

[EN] Vehicle communications are one of the pillars of the development of Intelligent Transport Systems. This is a complex scenario, where several types of entities interact with each other, using a range of communication infrastructure. In this area there are several applicable technologies, with different advantages and disadvantages. Therefore, flexible and ubiquitous communication, capable of using any communication type, will allow Smart vehicles to use the most appropriate one to improve traffic movement systems. Although the use of Bluetooth has been considered in this field, it has normally been done in intra-vehicle communications, or if it has been done outside this field, for inter-vehicle communications, it has been done based on standard 4.2 or earlier versions. The Bluetooth BLE 5.0 standard has features that allow the use of this technology in previously unimaginable scenarios; in particular, the increase in range, and greater robustness in communications allowing the analysis of its use as an infrastructure to vehicle network. The preliminary results obtained demonstrate this viability and the potential of this technology in this fieldThis work has been supported by the project PRYSTINE which has received funding within the Electronic Components and Systems for European Leadership Joint Undertaking (ECSELJU) in collaboration with the European Union¿s H2020 Framework Programme and National Authorities, under grant agreement No. 783190, and from the ¿Instituto Valenciano de Competitividad Empresarial" ¿ IVACE.

Research study on inter-vehicle communication implementation in Malaysia

Vehicle-to-Vehicle (V2V) communications systems have recently drawn great attention, because they have the potential to improve convenience and safety of car traffic. Road accidents take the life of many people in the world each year, and much more people have been injuring and maiming. Statistical studies show that accidents could be avoid by 60% if drivers were informed only half a second before the accident. The objective of this report is to make an analysis of the possibility of implementing this technology in Malaysia. This research study is as guidance to develop a concept of V2V system. Applications with early deadlines are expected to require direct V2V communications, and the only standard currently supporting this is the IEEE 802.11p, included in the wireless access in vehicular environment (WAVE). The combination of WAVE and GPS is a good idea to forming collision avoidance system. The GPS system determines the location of vehicles and the WAVE system forming an ad- hoc peer-to-peer networking among the vehicles.V2V communication enable vehicle to communicate with their neighbouring vehicles even in the absence of a central base station to provide a safer and more efficient roads and to increase passenger safety. This technology can be implements in Malaysia but in order to do it some changing had to be made first to ensure the effectiveness of the technology. V2V communication should have a Doppler sensor as a device sensor that can integrates with cruise control to form adaptive cruise control. Other than that, it also need WAVE to assure a reliable communication system between vehicles. The GPS system is needs to determine exact location of car that can be use in roadways environment such as overtaking situatio

Traffic Characterization of an Internet of Things(IOT) Network Architecture

Internet of things (IoT) is an evolving paradigm that is currently getting more attention and rapidly gaining importance. The basic idea of IoT is to connect everyone and everything to the Internet for information exchange. It is essential to develop a clear understanding of characteristics of IoT traffic sources as well as to find a traffic model that efficiently characterizes the statistical behavior of IoT traffic. Since many IoT devices generate relatively small sized data, we are particularly interested in an IoT network architecture where data from a number of different IoT devices are aggregated at an IoT gateway. We focus on characterizing the IoT aggregated traffic pattern for three common IoT applications with real-time and non-real-time quality of service (QoS) requirements. These applications include healthcare, smart cities, and video surveillance. Our study is based on generating a real IoT traffic trace in a lab by using various sensors and devices in the aforementioned applications. The generated traffic trace is transmitted wirelessly over the air using Wi-Fi technology to an IoT gateway. The input network traffic to this gateway is characterized. In the experiments, the amount of input traffic to the gateway is varied and different traffic patterns for each of the selected applications are examined. Statistical tests and parameters are used to determine the best matching packet inter-arrival time distribution for different traffic penetrations. Moreover, we also examine packet size distributions. Based on our empirical data, the experimental results indicate that IoT packet inter-arrival time follows a Pareto distribution. However, it can be better modeled as a Weibull distribution in some traffic patterns. Our experimental results also reveal that the packet size distribution of different penetrations of the studied IoT applications is not in a good match with the commonly used Geometric distribution. Furthermore, we investigate the impact of traffic characterization on the performance of the considered IoT network architecture for a certain availability of network resources using computer simulations
