JavaScript libraries, such as JQuery, are widely used in web applications. In these libraries' event delegation models, a DOM element's event handler is usually bound to its parent nodes. This makes it difficult for developers to figure out the user-defined event handlers of a specified DOM element. In this paper, we propose an approach that identifies the user-defined event handlers of DOM elements...
Sweep coverage is one of the important and recent issue for network monitoring in wireless sensor network (WSN). Sweep coverage is efficiently applicable where periodic monitoring is sufficient than continuous monitoring. Interference minimization is another main objective of topology control problem in wireless sensor network. Reducing interference in turn reduces the number of collision and packet...
In wireless ad hoc networks, misbehavior of nodes in computation of backoff value is one of the problems that affects the performance at MAC layer. To overcome this problem, this paper proposes a solution in which Contention Window subrange is specified by the receiver to the sender through CTS/ ACK packet. The advantage of sending the Contention Window subrange is, it is easier to detect the misbehaving...
The SAGITTA Demonstrator is a novel UAV with a digital flight control system being developed by the Institute of Flight System Dynamics of Technische Universitat Munchen. This paper presents the enhancement of the integrated auto flight system software by a monitoring / fault detection and diagnosis module. Its algorithms are designed to assess the health status of the flight control system components...
Human motion and posture detection based on the multi-nodes sensors will help people to realize the law of body's movement through obtaining the kinetic parameters, so that it can be used as a quantitative analysis tool for some specific applications such as health care, sport training and military affairs, etc. Compared with optical method, inertial sensors for body motion analysis have advantages...
Security in wireless sensor networks is critical due to its way of open communication. Local monitoring is one of the powerful technique to secure the data and detect various malicious activities. In local monitoring, neighbour nodes observe the communication between current sender, current receiver and next hop receiver to detect the malicious activity. To make sensors power efficient, sleep-wake...
In the context of the national smart grid construction, unstable power supply by traditional distributed energy resources for monitoring equipment is a problem. Aimed at the problem, based on the technology of high-voltage Magnetic Resonant Wireless power transfer technology, a full solution, a system for monitoring equipment of High Voltage Line, is proposed. In this paper, the key technologies and...
Carbon monoxide (CO) is an odorless, tasteless and colorless gas in which it is difficult to be recognized by human beings. CO gas that enters the human body at a certain concentration has negative impact on health. A monitoring system which can recognize the amount of CO gas concentration, especially for the indoor is needed to cope with this problem. In this paper, monitoring system is designed...
In recent years Delay/Disruption Tolerant Network (DTN) has been identified as the most promising and challenging areas of wireless communication where sparseness and delay are particularly high. It is emerging as a promising network in the areas of disaster response, inter-planetary, vehicular, military/tactical, underwater, satellite networks. DTN is characterized by the large communication latency...
The receiver system is an important part of FAST (Five-hundred-meter Aperture Spherical Radio Telescope) and plays a key role in determining the performance of the telescope. The receiver design requires synchronization among the digital instruments and accurate timestamp, because time synchronization of astronomical data before and after it is recorded and processed is of vital importance for the...
In hospitals, telemetry is utilized by physicians to provide accurate diagnosis for their patients. The increase penetration of wireless technology in healthcare environment for powering, monitoring and sensing purposes of implanted or attached devices to human patients' triggered new challenges in designing reconfigurable wireless transceiver intended for healthcare that can operate in multi-frequency...
In this paper a problem of compressing data containing information on basic parameters of network traffic is considered. Six test sets with different types of network traffic for known monitoring tool Wireshark are formed. Analysis of compression efficiency for these datasets by widely used archivers is carried out. It is shown that the main part of memory in compressed data relates to timestamps...
In this paper was performed a detailed comparison of the propagation models available in the ICS Telecom software, in order to make a proposal for the configuration of the propagation models to the National Spectrum Agency - ANE, an Colombian government office, for different telecommunications services. ANE has the function of monitor, control, manages and plan the radio spectrum in Colombia and the...
This paper discusses the problem of detecting wearable RF devices used in elderly care. Events such as blood sugar level drop, or physical fall of the elderly person, are stochastic events and are digitally recorded and/or broadcast to a monitoring system through home. The stochastic nature of the events and independence of the digital broadcast for different events are exploited here to allow localization...
In industrial plants, there is a mix of devices with different security features and capabilities. If there is a mix of devices with various degree of security levels, then this will create independent islands in a network with similar levels of security features. However, the industrial plant is interconnected for the purpose of reducing cost of monitoring with a centralized control center. Therefore,...
A hierarchical monitoring architecture is proposed in this paper. Monitoring information can be filtered and correlated at each hierarchical level guaranteeing high scalability of the management plane. Simulations, based on measurements on a commercial system, show such high scalability.
An accurate and robust channel spacing monitor is proposed for denser Nyquist-WDM system. Based on low speed processing at the receiver, less than ± 150MHz estimation error is experimentally guaranteed and the robustness of the method is investigated.
Ionospheric scintillation monitoring is becoming an increasing research activity in order to devise countermeasures to the harmful effects ionospheric activity has on positioning services based on Global Navigation Satellite Systems (GNSS). The amount of amplitude fluctuations in GNSS signals due to scintillation is estimated by the �������� index. For this purpose, traditional closed loop architectures...
The aim of this paper is the discussion of the main features implemented in an Android application for ECG processing. It was designed to use a mobile phone, connected by Bluetooth to a battery-powered ECG device, as a signal acquisition layer in a Telemedicine platform. The Android application receives the ECG data according to a simple protocol. The Bluetooth pairing process is made by the proposed...
Group communication based on multicast enables efficient one-to-many and many-to-many distribution of real-time data. Multicast communication would therefore be beneficial to popular Internet applications such as IPTV, on-line multiplayer games and audio/video conferencing, and is considered as an important network service for future CCN/ICN architectures. However, multicast exists in many flavors...
