The next generation mobile networks (NGMN) are over-taxed by the increasing demand of on-the-go content access. Standards bodies and researchers are building solutions that offload the traffic demands from the NGMN infrastructure to small cells. We motivate a taxicab cloud as a mobile ISP that offloads traffic demands from NGMN to under-utilized licensed bands such as TV whitespaces. This cloud consists...
Aerial surveillance and mapping is a primary application area for small Unamnned Aerial Vehicles (UAVs). Large areas may need to be mapped, leading to long missions. However, mission duration is restricted by the fuel capacity of the UAV. This necessitates refueling the UAV for successful mission completion. All points of interest may not be reachable from a single refueling station and hence multiple...
The Connected Revolution has reached the automotive industry and the Internet penetrates into the modern vehicles. Formerly acquiring data from a vehicle was the tool of Fleet Management Systems handling commercial vehicles. In the recent years connectivity began to appear in the passenger vehicles also. The first features were infotainment and navigation, having low security needs remaining far from...
Localization methods play an increasing role in many of today's Intelligent Transportation Systems (ITS). In the context of this work we concentrate on improving the localization accuracy of passengers in public transport vehicles, e.g. as part of automated registration, counting or ticketing systems. In these applications each passenger's ticket could be designed as a mobile wireless sensor node,...
The main innovative idea of the proposed cyber physical system is step-by-step transfer of traffic lights from the ground to a virtual cloud space for vehicle management, equipped with a mobile gadget or computer, which displays on the screen map, route, coordinates of the road user and real traffic signals. The aim of this paper is to propose and discuss the formal modeling and technical realization...
Future device to device communication using the LTE system bring new opportunities for application development. In the case of wireless sensor networks, unmanned aerial vehicles with LTE capabilities could be used to increase the network lifetime, while ensuring high transfer rates between LTE capable sensor nodes and the aerial vehicles. In this article we propose a hybrid heuristic algorithm able...
Despite the large and spectacular development in the field of vehicle safety, particularly in the context of driver safety needs, solutions remain insufficient and independent. In this paper, we propose a new system that has been dubbed 3SD "Security and Surveillance System for Drivers". It is a multifunction system as a complete package based on intelligent sensors and cameras that constantly...
In the last twenty years, vehicles have become equipped with various sensors and resources, making them capable to communicate, to share resources and to behave cooperatively. This gave rise to the concept of vehicular cloud (VC). Vehicular cloud can be described from the standpoint of applications and services offered by vehicles that belong to a Vehicular Ad hoc Network (VANET). Because of the limitation...
Vehicles belonging to a Vehicular Ad hoc NETwork (VANET) can form an ad hoc vehicular cloud in order to provide and to share services between the vehicles. These services may be divided into two categories: (1) Infrastructure as a Service (IaaS) describing physical resources shared as services such as data storage, sensor data, network and computing services; and (2) Software as a Service (SaaS) describing...
The current form of construction of combat infantry vehicles no longer corresponds to changing requirements. Solving this problem requires reworking and upgrading vehicles taking into account the modernist knowledge and using the latest technologies. Substantial amount of modernization projects is devoted to a more modern infantry combat vehicle IFV-2, which has bigger potential for modernization...
Many studies show that the Dedicated Short Range Communication band is insufficient to carry increasing wireless data traffic in vehicular networks. The release of large TV spectra by FCC for cognitive access provides additional spectrum resources to solve the spectrum scarcity problem. However, FCC allows fixed devices to use high transmitting powers, while requiring portable devices to use significantly...
This paper addresses an optimal formation control of multiple two-wheeled mobile vehicles with the help of model predictive control. An optimal formation is automatically determined among pre-defined formations in real time according to the environment with the help of model predictive control. Experimental results are demonstrated to verify the effectiveness of the proposed approach.
The autonomous vehicle valet parking service (AVP) enables a vehicle to drive and park without any human interaction. The driverless vehicle has to follow the scheduled route and be parked in a parking lot automatically. Most fundamental technologies for autonomous vehicle valet parking service are controlling vehicle driving and parking. For autonomous driving, the path to near goal parking lot has...
We present a novel framework for collision free assisted navigation of a semi-autonomous vehicle in complex unknown environments with moving and steady obstacles. In the proposed system, a semi-autonomous vehicle is guided by a human operator and an automatic reactive navigator. The autonomous reactive navigation block takes control from the human operator in situations where there is the danger of...
This article deals with concepts of implementing the Internet of things that help both vehicle drivers and passengers get the continuous access to information services. The main feature of the proposed solution is the designing of the intelligent model of the virtual objects interaction that reflects the entity of the traffic network itself. The model provides the technology that helps to form the...
A semi-autonomous mobile self-leveling landing platform designed to launch, recover and re-launch VTOL UAVs without the need for human intervention is described. The landing platform is rugged, lightweight and inexpensive, making it ideal for civilian applications that require a base station from which a rotorcraft UAV can be launched and/or recovered on terrain that is normally unsuitable for UAV...
Most of the concerns of interest to mobile ad hoc networks (MANETs) are of interest in vehicular ad hoc networks (VANETs), but the details differ. Rather than moving at random, vehicles tend to move in an organized path. The intercommunication with roadside equipment can likewise be characterized fairly accurately. And finally, most vehicles are prohibited in their range of motion, for example by...
With the rapid development of wireless and mobile technologies (LBS, Privacy of personal location information in location-based services of a vehicle ad-hoc network (VANET) users is becoming an increasingly important issue. LBSs provide enhanced functionalities, they open up new vulnerabilities that can be exploited to cause security and privacy breaches. During communication in LBSs, individuals...
In cognitive vehicular networks, unlicensed secondary users heavily depend on spectrum sensing to find unused spectrum bands for communications. The performance study of existing spectrum sensing algorithms often overlooks the impact of secondary user mobility.Many of them assume secondary users stationary or with low mobility. In this paper, we investigate the joint impact of secondary user mobility...
Although governments have spent a great deal of effort to provide safer road networks, surface defects such as potholes, suck-in manholes, and defective street cuts are still commonly found on roads. The current methods of road surface monitoring depend on reports from drivers. However, these methods usually incur a long delay and thus it is difficult to obtain up-to-data information on road conditions...
