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...
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...
Today's vehicles are sensor-rich but computation-poor. To better assist drivers, current vehicles have a large number of diverse sensors, for instance, the 2017 Ford GT has over 50 built-in cameras and sensors that can determine speed, location, humidity, occupancy, mechanical positioning, and a wealth of other data. However, modern vehicles have little general-purpose computing capacity due to cost,...
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...
Serious disasters have been annually occurred in Japan. Particularly, in the Great East Japan Earthquake that occurred on March 11, 2011, the communication infrastructure was seriously damaged over wide areas. Due to such situation, more resilient network infrastructure that does not stop under challenged communication environment is required. In this paper, we propose a disaster information system...
Vehicular Cloud Computing (VCC) denotes a shared pool of computing resources in a set of wirelessly connected vehicles, which are available for on- demand and rapid access based on the pay-as-you-go fashion. VCC consolidates the benefits of Mobile Cloud Computing (MCC) and vehicular communications. Prior to the VCC concept being widely adopted, several research issues and challenges need to be carefully...
Mobile gateways are deployed to improve Internet services in Vehicular Ad-hoc Network (V aNet). In this vein, this paper argues the need for selecting an appropriate gateway for vehicles without access to the Internet according to certain criteria and based on a gateway discovery system. The proposed solution introduces a method of multiple-criteria decision analysis helping to find suitable gateways...
Cloud computing and Vehicular Communications are profoundly emerging fields towards realization of smart cities. While cloud computing is stage of development, vehicular cloud computing combines the benefits of Mobile Cloud Computing (MCC) and vehicular communications. Recent studies expect that vehicular cloud computing will be the gateway to the future of transportation systems. However, the development...
Mobile crowdsourcing concept has attracted attentions of researchers, developers and businesses in the last decade. This exact concept has also been used in the area of Intelligent Transportation System (ITS) mainly for collecting and distributing information about the current traffic condition. In this paper, we extend the mobile crowdsourcing concept to be used for an intelligent car park system...
In vehicular ad hoc networks (VANETs) the network services and applications (e.g., safety messages, vehicle navigation data) require an exchange of vehicle and event location information. VANET is an important research field of wireless sensor networks providing different applications such as real time traffic information for on road vehicles and related authorities. The integrated model of VANET...
This paper introduces the concept of using IoT and Cloud based technology in car parking services in cities. A high-level view of the proposed system is outlined. Our solution makes the ancient parking system smarter by leveraging the power of IoT and embedding it with the latest innovation of electronic sensors & computers. An IoT-based intelligent car parking system is described. A number of...
With the abundant on-board resources in smart vehicles, they have been considered major candidates for providing ubiquitous services. Processing and storage resources provided through on-board units along with a variety of sensing and communication capabilities can turn smart vehicles into potential computing engines that can be pooled to serve as powerful vehicular clouds (VCs). Computing tasks can...
In this paper, we present a mobility cloud platform called CarCloud that has been designed to facilitate the real-world deployment of ubiquitous mobile telematic applications to promote smart transportation. CarCloud leverages the mobility, sensing and communication capacities of mobile devices, and collaborates with sensors embedded in vehicles (e.g., accessed via OBD-II) and cloud services to form...
The advanced on-board vehicles' resources have given birth to the Vehicular Cloud (VC) concept. The VC is an emerging paradigm where individual mobile vehicles can be both cloud users and service providers, it enables vehicles that have sufficient resources to act as mobile cloud servers and rent out them to other vehicles. However, and with the high mobility of vehicles, user vehicles need to discover...
Wireless network solutions based on Vehicular Ad hoc Networks (VANET) are the main path for vehicle manufacturers and urban traffic management systems to find the bests in convenience, intelligence and safety of traveling and transportation. In the other hand, recent equipped vehicles with newest computers with powerful processors and huge storages are new resources for network service providers to...
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...
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...
Timeliness is one the most important factors in emergency management. Emergency notification mechanism has to be hassle free and quick, in order to have efficient response for any disaster, health-fix, act of terrorism, etc. In this paper, we present service architecture for emergency alert, using Fog computing. Fog computing brings cloud resources close to the underlying devices and IoTs, which makes...
