The vision of cooperative and automated driving sets new challenges for various industry sectors and research domains. In this context, the telecommunications community is called to provide reliable communication systems for vehicle-to-anything (V2X) communication that combined with sensor-based technologies will improve the performance of automated driving and increase further traffic safety. 3GPP...
Road surface conditions can cause serious traffic accidents, often with tragic consequences. Thus, an efficient system for mapping road anomalies can significantly promote the safety of drivers and pedestrians. This paper proposes a novel road anomaly mapping system that is able to detect a wide variety of conditions with high accuracy. The smartphone's accelerometer and GPS sensors are used for detection...
Participatory sensing (PS) is an emerging socio-technological paradigm in which citizens voluntarily participate and contribute to a distributed information system using applications installed in their hand-held devices. It can be found in a number of real-life applications, viz. traffic monitoring, air/sound pollution, garbage monitoring, social networking, commodity pricing, and so on. In these...
Commercially available wearables and apps that convert mobile devices into data collection hubs can be used to implement smart applications in aware cities. In this paper, we consider wearable devices on various human users as a networked cluster of computing power and information source in an Internet-of-People architecture. Applications can be developed to perform computation on this data and gain...
Vehicular crowdsensing takes advantage of the mobility of vehicles to provide location-based services in large-scale areas. In this paper, we analyze vehicular crowdsensing and formulate the interactions between a crowdsensing server and a number of vehicles equipped with sensors in the area of interest as a vehicular crowdsensing game. Each participant vehicle chooses its sensing strategy based on...
A growing interest in Internet of things (IoT) paradigm has enabled a wide range of physical objects and environments to be monitored in fine detail by using pervasive sensing and communication devices. In this paper, we develop an IoT framework that targets one of the biggest challenges in modern cities, namely, Parking Management. Populating parking facilities with sensors imposes unwarranted installation...
With an increase in the number of mobile applications, the development of mobile crowdsensing systems has recently attracted a significant attention in both academic researchers and industries. In mobile crowdsensing system, the remote cloud (or back-end server) harvests all the crowdsensing data from the mobile devices, and the crowdsensing data can be uploaded immediately via 3G/4G. To reduce the...
At the present, the traffic is really in a mess when the number of vehicles is increasing rapidly. As a consequence, finding a parking space is remarkably difficult and expensive. Therefore, solving this problem has attracted the attention of both scientists and companies. Our study also focuses on solving parking problem to relieve the traffic congestion, reduce air pollution and enhance driving...
Due to the extreme fast movement of traffic in the busy localities, the cases of road accidents are increasing day by day. Traffic Control Board made different speed limit for different places to limit the speed, but it is not possible to always monitor the infringements manually due to several factors.
Vehicular Ad-hoc NETworks (VANETs) have unique characteristics, such as the high mobility of nodes, which cause frequent losses of connectivity, turning technology and network selection into a complex problem. Moreover, due to the instability of networks and its fast change, this network selection requires information of the networks in advance, so that it can predict the quality of the networks to...
With the social development and vehicle increasing, traffic congestion becomes a pressing problem. Carpooling is one solution for traffic congestion. This paper begins with a motivation case and proposes a service-based method to automatically identify vehicles which travel together (i.e., Traveling companion) and provide carpooling candidates for users in heavy urban traffic. This paper focuses on...
Vehicles are not just a means of transportation anymore, but they are also moving entities that collect and transmit a great amount of local data, captured by sensors from the internals of the vehicle and from its environment as well. The consumers of this information include the passengers, especially the driver, and the environment, i.e. other vehicles, intelligent gates, centralized storage systems...
Today, in the era of Internet of Things, an enormous amount of research is going on in the direction of probing into vehicle's engine control units for collecting kinematic and diagnostic information, analyzing and integrating them with software platforms and providing valuable services to drivers and passengers. This is largely facilitated by the car's several sensors forming an in-vehicle network...
Location based services is a class of computing services that uses the consumer's location data in order to personalize and enable features and services. Services include those for mapping and tracking, emergency response and disaster management and location based advertising. Of these services, location based advertising, also knows as hyperlocal marketing, accounts for the largest market share....
This paper proposes an autonomous flying projector (AFP) that projects images from a micro aerial vehicle (MAV) on which a small projector is placed. The AFP works as a public and ubiquitous display, and has a potential for an expansion of projector applications (e.g., a digital signage moving in response to a distribution state of people, and the one following moving targets such as a person and...
In Japan, an effective disaster control is needed because Japan is prone to severe disasters including earthquakes, tsunami, typhoon, heavy rain and snow. Application of the ubiquitous sensing system is expected to be an effective disaster prevention system in disaster-prone Japan. In this paper, we examine the possibility to apply COMOSE (Co-Operative Mobile Sensor Environment) platform that collects...
Advanced vehicle safety is a recently emerging issue, appealed from the rapidly explosive population of car owners. Increasing driver assistance systems have been designed for warning drivers of what should be noticed by analyzing surrounding environments with sensors and/or cameras. As one of the hazard road conditions, road bumps not only damage vehicles but also cause serious danger, especially...
This paper explores direct phone-to-phone communication (via WiFi interface) among vehicles to support mobile sensing applications. Direct communication among drivers' phones is important in improving data collection efficiency and sharing participatory sensing information in an inexpensive manner. We design a practical and optimized communication mechanism for direct phone-to-phone data transfer...
Modern cities continuously struggle with infrastructural problems especially when the population is massively growing. One affected area is public transportation. In default of offering convenient and reliable service the passengers tend to consider other transport alternatives. However, even a relatively simple functional enhancement, such as providing real-time timetable information, requires considerable...
Smartphones have been widely integrated with GPS receiver, which may provide accurate location information of vehicles without cost increase. Traditionally, LBS applications obtain vehicle locations then using the Hypertext Transfer Protocol (HTTP) protocol uploaded to central servers with a fixed frequency. In this paper, we exploit an intelligent strategy of GPS sensing and transmitting. Explicitly,...
