The modern day car navigation systems have three main tasks: 1) Positioning, 2) Routing and 3) Navigation, where GPS has become the standard Technology that is being used. However GPS has some limitations when it comes to precision of the data presented. This paper presents the development of a new system hat deploys numerous novel wireless technologies to assist high precision localization and reliable...
In this paper we describe a system for indoor navigation in complex public or commercial facilities such as airports, train stations, clinics, museums, fairgrounds or conference centers. The concept of this approach is strongly focused on application in geographically distributed facilities containing multiple indoor areas, situated at various levels that are connected by stairs, escalator or elevators...
A Map aided Pedestrian Dead Reckoning (PDR) algorithm is proposed to mitigate the drift errors and step detection limitations of pedestrian dead reckoning algorithm with handheld sensors in indoor and outdoor spaces. Specific to this context is the changing lever-arm between the handheld device and the pedestrian center of mass that introduces a misalignment between the inertial sensors and the walking...
This paper discusses ‘InLoc’, an accurate and a robust positioning and tracking system using commercial mobile devices, with an integrated feature of route finding for the user from a source to the desired destination. The system exploits easily available building floor maps in raster form, with an easy conversion to vector model, eliminating the need of specially designed vector maps, thereby making...
Bus arrival and departure information is widely accessible specially provided by the local public bus services. Using a sophisticated GPS technology, bus companies are able to track their buses and let users know the estimated time of arrival. Users nowadays are depending more on the information, but the convenience is only available for public bus services in the city. In this work, a bus arrival...
Based on the Pan-sensing and positioning system and the vehicle monitoring and dispatching system under GPS / GIS cooperation, designed the overall architecture of the intelligent logistics and distribution information system under the Internet of Things environment. Established the information service systems with information acquisition, processing and application capabilities by using the Pan-sensing...
In order to increasing the stability and performances of the hexarotor, the autonomous control method needs to be implemented, which based on the parameters from the sensors; like accelerometer, gyroscope, compass, and global positioning system (GPS) sensor. Based on that, we designed a flight controller that combined these sensors using our proposed control algorithm which based on proportional integrator...
Location is an important context in everyday activity. Outdoor positioning, through the use of the Global Positioning System (GPS), has been a mature technology. Indoor localisation, on the other hand, is still an active research area. While many popular techniques utilise new specialised, dedicated devices to enable precise indoor positioning, our investigation aims to solve the indoor localisation...
Due to the increasing spread of location-aware applications, developers interest in user location estimation has grown in recent years. As users spend the majority of their time in few meaningful places (i.e., groups of near locations that can be considered as a unique place, such as home, school or the workplace), this paper presents a new energy efficient method to estimate user presence in a meaningful...
This paper reviews the proposal for a design of a wearable that describes the basis of a glove intended to help visually impaired people in their day-a-day activities. It uses wearable technology, such as sensors and actuators, that alert the user in case of an encounter with an obstacle in two directions (according to the position of the hand), and the proximity to a desired destination. In the first...
This study was undertaken to establish basic technologies and knowledge of aerial photography and its application to support safe rowing. For the water sport of rowing, managers and coaches use a motorboat to follow a rowing boat for coaching and safe rowing observation. Utilization of a motorboat gives rise to numerous problems in terms of pulled waves, narrow visual ranges, limited tracking of boats...
Machine-to-Machine (M2M) communication has been a hot topic for researchers for last few years. Energy efficiency is one of the major issues in M2M devices. In order to increase the energy efficiency of M2M battery-based devices, this paper proposes an energy efficient clustering technique in M2M based on Affinity Propagation (AP). It uses the simple idea of head rotation among the most appropriate...
A smart city is emerging as an application of information and communication technologies to mitigate the problems generated by the urban population growth. One of the smart city solutions is to establish an efficient fleet management relating to the use of a fleet of vehicles (e.g., ambulances and police vehicles). The most basic function in a fleet management system is the real time vehicle tracking...
Global Navigation Satellite System (GNSS) is a well known method to detect the location. A GNSS sensor is integrated with wireless sensor nodes to know its location distributed in geographically wide area, along with some energy harvesting device such as a solar cell. However, the GNSS sensor consumes relatively larger energy and requires longer sensing time for tracing satellites everytime, compared...
This paper describes the design of a newly-developed Autonomous Underwater Vehicle “HOBALIN” by National Maritime Research Institute, Japan. The major mission of the AUV is to explore hydrothermal vents by taking photographs hovering over the seafloor at an altitude of 2–5 meters, up to 2,000 meters depth. “HOBALIN” was developed as a practical AUV based on the design of the AUV “TUNA-SAND”. Therefore,...
This article presents a new methodology of enriching digital maps in order to reason upon the traffic sign compliance, of traffic participants. The Open Street Map (OSM) data is augmented with a new layer for road orientation and road intersections in order to support not only map matching, but also reasoning processes on the compliance to traffic regulations provided by traffic signs. In order to...
Detecting congestion in urban areas is critical and creates a myriad of complications. Intelligent Transportation Systems (ITS), which are trending in recent years, are used by researchers to engage problems related to congestion and transportation. However, due to the open access in urban area structures, it is less feasible to handle rife data that is generated from vehicles and infrastructure....
The need of accurate and reliable positioning in various location-aware safety critical transportation applications is increasing day by day. The Global Positioning System (GPS) is not able to provide lane-level vehicle localization without the aid of differential corrections. It also suffers from signal outages in urban areas resulting in a complete loss of location information. Therefore, GPS independent...
Rapid technological advances in electronics, computers, software applications and the aerospace industry have dramatically decreased the cost of implementation while increasing the availability of Unmanned Aerial vehicles (UAVs). UAVs are those flying aircrafts that runs without an onboard pilot. They are controlled through a computer or remote. The main motive of this survey is to scrutinize theoretical...
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...
