Knowledge of a flow field is crucial to guide oceanic mobile sensing platforms; yet, existing regional ocean models provide insufficient spatial and temporal resolutions for precise guidance of mobile platforms. By combining computational ocean models with real-time data streams collected from mobile platforms, generic environmental models (GEMs) provide high-resolution predictions of ocean currents...
Smart environments such as smart grid, smart transportation, smart buildings are upon us because of major advances in sensor, communication, cloud and other cyber-physical system technologies. The collective name for interconnected sensors, placed on "things" within fixed cyber-physical infrastructures, is Internet of Things (IoT). IoT enables cities and rural areas to become smarter and...
In this work we investigate the benefits of an hybrid architecture integrating both mobile roadside units, and stationary roadside units supporting the operation of vehicular networks. Since traffic fluctuates, an architecture employing just stationary roadside units might not be able to properly support the network operation all the time. Similarly, an architecture composed just of mobile roadside...
Just imagine what happens if you are pulled over by a Traffic sergeant, and you did not have your driver's license with you. Without it, you cannot drive a vehicle on public roadways so it is possible for cop to fine you. Therefore, it is important for you to carry your Driver's License everywhere. On the other side, it is hectic job for a Cop to verify if the Driver's license is original, is it valid,...
In the recent decade the VANET has been emerged as a prominent field for research and it receives considerable attention. VANET uses different specifications of the WLAN 802.11 family. It takes the basics of ad hoc network and the VANET creates a network with a collection of independent entities with the ability to communicate among themselves. The Adaption to the various 802.1 family causes a remarkable...
An Android application (app), called Real Time Range Tracker, was developed as part of a Naval Innovation Science and Engineering program and provides near real-time “line of sight” range between mobile smart devices. In order to properly design tests and analyze test results, the accuracy of the data generated by the app must be fully understood along with any associated measurement uncertainties...
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...
Public transport plays an importation role in our daily life. The information related to passengers satisfaction is very beneficial for optimizing the transportation service. This paper investigates an application of mobile crowd sensing to detect and analyze the riding quality of public transport vehicles. The lightweight system leverages sensors equipped on participants' smartphones to collect surrounding...
In this keynote, we look the fundamental limits of the information propagation speed in large scale mobile and intermittently connected networks, where end-to-end multihop paths may not exist and communication routes may only be available through time and mobility. We first introduce some analytical tools to derive generic theoretical bounds for the information propagation speed in this networks....
This paper presents a decentralized consensus formation control using fuzzy wavelet neural networks (FWNN) for a group of homogenous, mobile four-Mecanum-wheeled omnidirectional vehicles (MWOVs) with uncertainties. The dynamic behavior of each MWOV is remodeled by a three-input-three-output second-order system model and the multi-MWOV system is modeled by graph theory. By online learning the system...
We present cooperative moving object tracking with multiple mobile sensor nodes, each equipped with a multilayer laser scanner. Moving objects in the laser-scanned images are detected by a binarized occupancy grid method. The sensor nodes send the information of the detected moving objects to a central server, which estimates the size, position, and velocity of those objects using a Bayesian filter...
This paper investigated the repeatability of the human motion as a first step to improve the usability of the saddle type interface using human twisting motion for the Personal Mobility. Our proposed interface uses not only conventional translational human motion but also twisting motion, namely it makes full use of the human motion characteristics. The basic experimental results also showed that...
With an innovation in mobile technology, trend of use mobile device as function to record individual activity is increasing in various fields. In order to determine the taxi meter quality of service in the urban area, we used mobile data to determine cause and fact. Normally, “Taxi Route for Fare-Rate Calculation” and Customer survey. In the first part, we developed an algorithm to calculate taxi...
In research community vehicular networks are very popular these days as in many countries vehicles are interested in downloading and updating data at Road Side Units (RSUs). As RSUs are used as router to forward data of vehicles to outside world and RSUs are also equally used as buffer points to forward data of one vehicle to other vehicles moving across the road. In the proposed work RSUs are used...
Based on the United State transportation department recent statistics, individuals who drive while sending or reading text messages are 23 percent more likely to be involved in a car crash than other drivers. A crash typically happens within an average of three seconds after a driver is distracted. The purpose of this paper is to design and develop smart mobile application that block the driver's...
Vehicular Ad Hoc Network (VANET) is an evolving technology of today's world and is expected to be all pervasive in the near future. The vehicles in VANET possess mobility as well as computational processing power. The vehicles collaboratively form the ad-hoc network and are peers of each other. This paper discusses solving Traffic Congestion as an application of VANET. We have simulated the work of...
This paper reports on an ongoing design-driven action research effort using information systems to promote transparency in the European freight transport industry. The current lack of transparency is linked to a growth of unsustainable business practices. This can be countered by reducing information asymmetry. However, access to reliable information is hampered by the severely fragmented organizational...
Below the Media Access Control (MAC) layer is the Physical (PHY) layer which deals with the actual transmission of the bits received from the MAC layer above into electromagnetic signals. This layer is optimized to implore power management in wireless networks. Power management is a crucial issue in wireless and mobile networks. In this paper, we propose an Adaptive Context-Aware Rate Selection (ACARS)...
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...
Easiness of public & tourist's travel within a city is an important task for central and State Government. They have to access a combination of public transport options like metros, trams, buses and private options like cabs services and hired vehicles. Delhi, being the capital city of India, enjoys the usage of public transport by millions of travelers. Currently all route information on mobile...
