An Events Data Recorder (EDR) is a unit that record movement parameter of a vehicle mainly used for accident analyzes purposes. Many of EDR has designed for automobile, however they have to be physically connected to sensors integrated with the car's engine and system. That is why it is not easy deploy and very high cost. In this research, we present preliminary design of a simple low cost EDR prototype...

The emerging technology of FANET has many applications in civilian and military field like search and rescue mission, surveillance, reconnaissance, monitoring etc. which create temporary mobile ad-hoc platform for communication and data collection. For such applications, main requirements are maintaining and sustaining connectivity...
This paper presents an efficient approach for collecting data in mobile wireless sensor networks which is specifically designed to gather real-time information of bikers in a bike race. The approach employs the recent HIKOB sensors for tracking the GPS position of each bike and the problem herein addressed is to transmit this information to a collector for visualization or other processing. Our approach...
As Location-Based Services (LBSs) are widely used in smartphone applications, Global Positioning System (GPS) becomes one of the main sources of a smartphone's energy consumption. This paper presents an energy-efficient positioning scheme for smartphones called EEPS (Energy-Efficient Positioning Scheme). EEPS adaptively performs the positioning of a smartphone considering the interesting regions of...
The wireless sensor networks (WSNs) are one of the popular information and communication technologies (ICTs) in different application areas. One of the important issue and technology in WSNs is to collect sensing data efficiently and deliver them to base station (BS) reliably. In most previous researches and proposed methodologies are using Geographic routing techniques. Based on them, the sensors...
Tagging animals with radio devices is a commonly used technique in wildlife and conservation biology. We study the problem of localizing a tagged animal using the audio output of an off-the-shelf receiver mounted on an autonomous Unmanned Aerial Vehicle (UAV). This problem is motivated by the application of taking pictures of bears to document their interactions with the environment after contact...
The Dramatic increase in the traffic flow raises demand on innovative technologies that can improve safety and efficiency of transportation systems. Road safety can be substantially enhanced by the deployment of wireless communication technologies for vehicular networks, which enable new services such as collision detection traffic management, and further communication facilities between moving vehicles...
The proliferation of powerful mobile devices, along with the increasing demand of location information, has driven the researches to develop positioning applications with higher accuracy. In this paper, we build an Android application which achieved the aim of seamless positioning between the inside and the outside. The system contains four parts: outdoor positioning, which uses GPS and Baidu Map,...
Nowadays, Auto-navigation robots are cutting-edge and widely used and investigated by robotics experts. An autonomous robot can function and complete every task without any human guidance. Since it functions without human intervention, therefore obstacles detection and localization are significant and need to figure out. First, how the robot obstacle detection? Second, how to control auto-navigation...
The complexity to autonomous-navigate a flying robot is much higher compared with a ground-based robot. During autonomous-navigation, the flying robot should have the intelligent to fly from current location toward the desired location. Therefore, the system must address three problems facing by the flying robot. First, where am I? It's the perceive level of the flying robot to sense the environment...
We consider personal navigation systems in devices equipped with inertial sensors and Global Positioning System (GPS), where we propose an improved Pedestrian Dead Reckoning (PDR) algorithm that learns gait parameters in time intervals when position estimates are available, for instance from GPS or an indoor positioning system (IPS). A novel filtering approach is proposed that is able to learn internal...
To our knowledge, this paper investigates the first application of the marine data sampled by multiple underwater gliders in the area of the South China Sea. We summarize six main characteristics of the sampled marine data. Due to the characteristic of big data volume, how to display these data is an important and difficult problem. In order to solve this problem, we process the marine data through...
Traffic controlling is the key requirement in transportation system. Traffic management requires high skill based automated solutions as an alternative of the manual methods such as human intervention viz. traffic policemen, traffic lights and safety cameras. Due to traffic jamming the commuter fails to reach the destination in time. Analyzing road traffic data takes step towards controlling the traffic...
This manuscript describes a UAV implemented with vision and laser based localization algorithm to track and land on a moving platform. Specifically, a pre-designed marker is installed on the moving platform and a downward facing monocular camera is mounted on the UAV for pose estimation. For a robust and precise UAV height estimation, a LiDAR scanning range finder is utilized to determine accurate...
This paper addresses the problem of autonomous navigation of a quadrotor helicopter using state estimators when the GPS signal is not available. The main objective is to estimate the translational position and velocity of the flying machine. The observer proposed uses a double integral approximation of the acceleration defined in the mathematical model in order to estimate the states previously mentioned...
In the rivers area, it has become frequent problems with illegal dumping, flood, inundation, and damage. We need the support and understanding of the problems quickly. Future measures also require. River basin is a wide range. Only the river administrator is difficult to perform adequate monitor and response. River Information Management System was developed by the collaboration with the Ministry...
Depression is a major public health issue with directand significant effects on both physical and mental health. In thisstudy, we analyze smartphone sensing data to find differentialbehavioral features that are correlated with depression measuressuch as patient health questionnaire (PHQ-9). Our approachuses an innovative multi-view bi-clustering algorithm. It takesmultiple views of sensing data as...
Success of a cooperative mission entirely depends on precise navigation information of each UAV. Though present day UAVs are equipped with GPS, the UAVs have to rely only on navigation information obtained from inertial navigation system while operating in GPS denied environments. This research work, addresses the problem of establishing a GPS protected wireless MAV network (WIMAN) using three classes...
This paper presents a method for localizing a land vehicle using low cost MEMS IMU sensors and a terrain map in global positioning system (GPS) denied environment. Previous attempts to localize a vehicle based on terrain information used a tactical grade IMU which is not cost-effective on a commercial scale. On the other hand, MEMS sensors are very cheap but cannot provide accurate attitude estimation...
Accurate sensing of the spectrum is one of the prime requirements for efficient functioning of cognitive Radio systems. But accurate sensing is a complex process, as signals of different modulations, coding methods and power levels along with fading and noise are present in the given radio environment. Collaborative sensing techniques can help to improve the sensing accuracy. One such collaborative...
