This paper presents the architecture of GENI edge cloud computing network in the form of compute and storage resources, a mobile 4G cellular edge and a high speed campus network connecting these components. This deployment is available across fifty campuses in the US, all interconnected via a nationwide Layer-2 network. We present these capabilities in the context of vehicular sensing and control...
Gamma Deployment is a metric for evaluating the distribution of roadside units in vehicular networks in terms of two parameters: a) the inter-contact time between vehicles and the infrastructure, and, b) the share of vehicles that must respect the inter-contact time guarantees. We envision the use of the Gamma Deployment metric when the network designer intends to distribute check-points along the...
Cloud-based vehicular networks is a new paradigm to improve the vehicular services through distributing computation tasks between remote clouds and local vehicular terminals. To further reduce the latency and the transmission cost of the computation offloading, we propose a cloud-based Mobile Edge Computing (MEC) offloading framework in vehicular networks. In the framework, efficient computation offloading...
Boosting trajectory planning is the basis of the gliding trajectory planning for land-launch hypersonic vehicle. Its terminal states are essential to subsequence flight. Besides, mobile launch is an important means to promote the survivability of hypersonic vehicle. To plan the boosting trajectory for hypersonic vehicle and satisfy the strict terminal constraints, firstly we analyzed and established...
The trends are reviewed in the development of unmanned transport systems. There is highlighted an increasingly important part of various range vision/location systems. There is described an architecture of the on-board computer network supplying information to the control systems of the mobile vehicles with the enhanced level of independence and totally unmanned. The proposed architecture provides...
This paper describes a formation control algorithm for omnidirectional mobile vehicles with high robust performance. It is shown that the associated nonlinear control problem can be made tractable, using the tensor-product transformation model, by transforming the complex nonlinear and uncertain model into linear parameter varying (LPV) form. Considering the convex hull of the dynamic model, the varying...
Nowadays, vehicles have shown great potential in crowdsensing. To guarantee a good Quality of Service (QoS), stimulating enough vehicles to participate in crowdsensing is very necessary. In this paper, we focus on the incentive mechanism design in the vehicle-based nondeterministic crowdsensing. Different from existing works, we take into consideration that each vehicle performs sensing tasks along...
Understanding vehicle mobility is essential for devising successful protocols for vehicular communications. Vehicles move at varying speeds on roads whose complexities range from plain highway lanes to urban boulevards with intersections/circles, traffic lights and various points of interest on them. This mobility pattern combined with vehicle density fluctuations depending on location and time makes...
Currently, most automatic traffic incident detection systems rely heavily on data collected from fixed sensors such as inductive loop detectors and surveillance cameras. However, fixed sensors are difficult to install and maintain. Moreover, it is quite costly to deploy a large number of fixed sensors to cover a broad area. It is potentially more efficient to use vehicles as mobile sensors to collect...
In this paper, we present two novel guidance laws for an unmanned aerial vehicle (UAV) equipped with a fixed camera to track a mobile ground target. The system dynamics is established in the level local coordinate frame, removing the need of converting the target location information to the global inertial frame. The first guidance law is developed using backstepping technique requiring the estimation...
Cognitive Radio (CR) is a promising technology to solve the spectrum scarcity. Spectrum sensing becomes more challenging in Cognitive Vehicular Networks (CVNs) due to Secondary Users (SUs) mobility. Current studies on cooperative spectrum sensing usually assume that sensors are static and independent, which is unreasonable in vehicular networks with dense traffic. In this paper, we investigate the...
The rapid increase of portable devices providing a multitude of mobile applications have led to excessive cellular traffic demands and consequently to the overload of cellular networks. Recently, migrating this traffic by opportunistic vehicular networks has attracted a great interest and appeared as a promising solution. Indeed, only a limited set of vehicles (seeds) is selected to download objects...
In vehicular networks (VN), the response time is critical, whereas, an autonomous and efficient way of preventing hazardous situations on roads plays an important role in the successful deployment of the system. Trust or reputation models often need to be integrated with inter-vehicle communication protocols in use to avoid selfish or malicious behavior by the vehicles exploiting the system. Existing...
The emergence and evolution of any package technology is driven by market trends as experienced by the end application. With the maturation of the mobile market, the trends for Smartphone and other mobile devices are more than ever for lower cost. Meanwhile, a higher degree of functionality and performance, thinner profile, and longer battery life are some of the additional market drivers seen in...
The development and evaluation of Vehicle-to-X (V2X) applications using mobile cellular networks by means of field tests is time consuming and expensive. Simulations can speed up the development and largely reduce evaluation costs. However, due to the complex nature of the network involved, it is quite difficult to be certain that the results obtained using simulation will actually match the observable...
Automotive connectivity standards promise to usher in new apps and services that utilize vehicle-to-vehicle communications, and mobile app trends point to the potential of direct device-to-device connections. The convergence of the two, made possible by new hardware, system software, and programming abstractions, promises to realize next-generation mobile ITS apps. The city-scale impact of such convergence...
Developing countries like India needs a significant improvement in infrastructure such as Roads or Highways. Construction of these highways is a costly affair, which can't be invested by the government alone. Normally Public private partnerships are made to construct such a huge projects. The money spent on these projects can be regained by collecting toll from the passengers who use the roads. The...
In Vehicular Ad-hoc Networks (VANETs), any vehicle uses a location service to get an up-to-date data of all vehicles' positions in its vicinity. Many location services rely on infrastructures to perform location update and location query tasks. However, the infrastructure penetration rate may differ from one region to another. We propose in this paper a new location service called Vehicle-Aided Location...
We consider a surveillance system for public transport vehicles, which is based on the collection of on-board videos, and the upload via mobile network to a central security system of video segments corresponding to those cameras and time intervals involved in an accident. We assume that vehicles are connected to several wireless interfaces, provided by different Mobile Network Operators (MNOs), each...
