Upconversion detection can isolate the temporal and wavelength window over which light can be efficiency received. Using appropriate designs the ability of an eavesdropper to damage, measure, or control QKD receiver components is significantly constricted.
Cardiogenic shock is a life-threatening medical condition with mortality rates of 70–90%,which can be reduced to 40–60% with aggressive and immediate treatment. The aim of this paper is to design wireless transmission system with a three lead ECG, temperature and pulse meter for the use in ambulance during life threatening conditions like cardiogenic shock. There is a need for a system which can serve...
We demonstrate an adaptive polarization-state monitoring and stabilization scheme for one-way polarization-encoded QKD. Polarization references are sent at a repetition rate that is adapted to the polarization drift condition to maintain a low QBER.
Most current results on coverage control using mobile sensors require that one partitioned cell is the sole responsibility of one sensor. In this paper, we consider a class of generalized Voronoi coverage control problems by using higher order Voronoi partitions, motivated by applications that more than one senor is required to monitor and cover one cell. We introduce a framework depending on a coverage...
In this paper, we introduce a road condition sharing system using Vehicle-to-Vehicle communication in various communication environment. Japan is prone to natural disasters. In addition, traffic hazards and traffic accidents occur due to snow. A wide range and quick condition understanding and monitoring are needed. In addition, it is important to understand the condition of the destination and the...
In satellite navigation the receivers should be zero-value calibrated in order to measure the zero-value offset, and calibration modes of different types of receivers are also different, which should be studied with pertinence solutions. Through analyzing the characteristics of different types of receivers, the paper studies a zero-value calibration method of the BeiDou monitoring receiver (UniNAV...
Related automatic dependent surveillance(ADS) is one kind of Air Traffic Control(ATC) surveillance technology has been well developed by the international civil aviation organization. In order to satisfy both management and monitoring of the general aviation and commercial aviation, the system uses 1090 ES and UAT double data link mode system model to. This paper puts forward a kind of ADS-B digital...
Wireless sensor networks (WSN) face different security threats that disrupt the normal activities and degrade the performance of the networks. The wormhole attack is one of the most severe security attacks in WSN. In this paper, we analyze the effect of the wormhole attack in Optimized Link State routing (OLSR), which is a standard proactive routing protocol for WSN. A modified version of wormhole...
Numerous works have investigated the vulnerability of Global Navigation Satellite Systems (GNSS) against attacks. Upcoming systems make provisions for cryptographic civilian signal protection. However, this alone does not fully protect GNSS-based localization. In this paper, we show that attacks at the physical layer, without modification of navigation messages, can be severely effective. We analyze...
Recent trends in wearable applications demand flexible architectures being able to monitor people while they move in free-living environments. Current solutions use either store-download-offline processing or simple communication schemes with real-time streaming of sensor data. This limits the applicability of wearable applications to controlled environments (e.g, clinics, homes, or laboratories),...
According to the characteristics of Jinggangshan geological disasters and the prevention of geological disasters in the status quo, a design has been developed in sensor technology as the foundation, using network transmission as the means of communication, geological disaster prevention management system with database, and spatial information technology as the core. The system realizes the disaster...
Ionospheric propagation is harmful for the electromagnetic signals broadcast by Global Navigation Satellite System (GNSS) satellites, mainly because of the presence of electron density anomalies. GNSS receivers are indeed of primary importance in scintillation and Total Electron Content (TEC) monitoring, especially at low and high latitudes, where scintillations are more frequent. Professional dual...
Perspective method for the monitoring and on-line modulation analysis in the HF band is presented in this paper. The workplace for the on-line analysis of analog and digital modulations consists from the digital receiver IZ225 and a PC with adequate SW. The original program for the on-line modulation signal analysis was designed in the programming environment CipherCAD. The type of modulation, its...
Tire pressure monitoring system (TPMS) requirement is increasing everyday because of the increase in number of accidents due to sudden burst or loss of pressure as it is not possible to manually check the tire condition while running. There is a need of an automated system which can alert the driver about the tire condition and take the corrected actions. Speed plays a major role in the performance...
Wireless Sensor Networks (WSN) featuring portable devices are widely used for healthcare applications such as real time patient monitoring. For such applications, design constraints are set on the amount of energy, limited network capacity (short communication range and low bandwidth), processing and memory resources in each node. In the framework of the Real time Active PIxel Dosimetry (RAPID) project,...
Global Positioning system (GPS) is a satellite navigation system, which provides users with positioning, navigation, and timing (PNT) services. Ionospheric scintillations not only can reduce the accuracy of GPS/Satellite Based Augmentation System (SBAS) receiver pseudo-range and carrier phase measurement but also can result in a complete loss of lock on a satellite. To enable the study of Ionospheric...
Wireless body area network (WBAN) is a term used to describe a network of sensor devices connected wirelessly for communication on, in and near the body to obtain physiological data from sensor devices. This paper explain the implementation of WBAN for monitoring body temperature, heart beat rate and oxygen saturation in blood. We develop the sensor reads physiological data to the desktop application,...
With the increasing number of the epilepsy patients (EPs) and their growing need for continuous monitoring and immediate respond to their seizures, the Epilepsy Patients Monitoring System (EPMS) is proposed to be the fit solution for the healthcare monitoring applications especially for the EPs monitoring application. This paper focuses on the use of Wireless Sensor Networks (WSNs) for the healthcare...
The transfer to wireless network form wired network has been a worldwide trend within the past years. Among all the up to date wireless networks, Mobile Ad hoc Network is one of the necessary and separate application. To achieve the diversity gains, cooperative communication utilizes nearby terminals to relay the overhearing information, has a great potential to improve the transmitting efficiency...
In 2013–2014, a new software and hardware controlling complex was developed and installed on the UTR-2 radio telescope. Controlling complex is designed for planning observations of discrete cosmic radio sources and areas of the celestial sphere, for programming control of UTR-2 pattern position with UTC time scale synchronization, for monitoring of control codes execution, as well as for control of...
