The authors propose a method for continuous monitoring of railway switch point blades based on radio frequency identification technology (RFID). Unlike the known monitoring methods, the method proposed allows to significantly expand the set of fixed diagnostic situations, as well as to control the mechanical parameters of moving elements of the switch. This paper describes the architecture of the...
Smart home is a house that uses Internet of Things(IoT) to monitor the environment, control the electric appliances and communicate with the outer world. Smart home is a complex technology, but a developing one. A smart home automation system has been developed primarily because in today's time and world, everybody's in a surge and wishes to screen and get to everything without being there physically...
The project aims at saving energy by detecting the vehicle movement on highways and switching on the block of street light ahead of it and simultaneously switching off the trailing lights. This project requires a sensor to detect the day and night and an array of piezoelectric sensors to detect the vehicle movements and accordingly switching on the lights ahead of it. So when there are no vehicles...
The paper presents the laboratory based model of an “Energy Management Unit” for the optimum use of the electricity produced from alternative sources like biogas plant and solar photovoltaic system at an agriculture farm. The electrical energy produced at the farm is distributed among the loads according to the availability and requirement. A diesel generator is used as a backup at the farm. If the...
In this article, the most essential aims on information protection of data processing centers in more flexible way to provide the necessary level of security of the existing environment of development and dissemination of cyber-attacks, which should be easily scaled to support any of its changes in the future, also in this paper Formation of competitive information security of data processing center...
In order to provide for the safe and expeditious passage of maritime traffic in congested waters, the U.S. Coast Guard is authorized by the Ports and Waterways Safety Act to establish, operate, and maintain Vessel Traffic Services (VTS) where needed. In larger areas, a VTS will generally require a communication system to enable the vessel traffic center and the participating vessels to exchange information...
A novel data source selection algorithm is proposed for ambulatory activity tracking of elderly people. The algorithm introduces the concept of dynamic switching between the data collection modules (a smartwatch and a smartphone) to improve accuracy and battery life using contextual information. We show that by making offloading decisions as a function of activity, the proposed algorithm improves...

Target Tracking issue in wireless sensor networks (WSNs) has gained much attention. Network lifetime and tracking accuracy are the important measurements for the target tracking mechanisms. However, most of approaches pursue one at the cost of the other. In some applications, the best tracking accuracy is not necessary to achieve if tracking quality is fixed by application users. This paper proposes...
Unobtrusive in-home monitoring systems are gaining acceptability and are being deployed to enable relatives and caregivers to remotely monitor and provide timely care to their elderly loved ones or senior clients, respectively, who are living independently. Such systems can provide information about non-movement or inactivity of the elderly resident. As prolonged inactivity could mean potential danger,...
The paper describes a software application running on Android mobile devices, used to help the neuromotor disabled patients to communicate with the clinicians or caretakers. The proposed application also include a telemonitoring (remote monitoring) component used to collect and process few physiological parameters of the patient. The application is part of a more complex communication and monitoring...
Main goal of this paper is a system created for the purpose of disaggregation appliances from the energy profile in the households and the evaluation of unusual activities carried out in a smart home appliances with the help of self-organizing maps (SOM), or individual model views for educational purpose. The paper focuses on the analysis of existing methods and techniques of the problem. The core...
The need of monitoring the water level of troughs is increasing. This is parallel with the growing of Wireless Sensor Network and Internet of Thing. By combining both approach, cattlemen can monitoring their troughs ubiquitous using their own personal device. This paper develop such system by using LoRa™ as the media between sensor hub and nodes, while Raspberry Pi is used as the gateway to push data...
In modern drive applications fed by voltage source inverters, monitoring systems are of advantage to reduce the maintenance costs and prevent outages. The proposed insulation monitoring method detects stator insulation defects by evaluating the current's transient response after step excitation by the inverter. Due to fast switching of the voltage source inverter at high output voltage dv/dt rates,...
Cognitive Radio Network (CRN) enables secondary users to borrow unused spectrum from the proprietary users in a dynamic and opportunistic manner. However, dynamic and open access nature of available spectrum brings a serious challenge of sustenance amongst CRNs which makes them vulnerable to various spectrum etiquette attacks. Jamming-based denial of service (DoS) attack poses serious threats to legitimate...
An abundance of spectrum access and sensing algorithms are available in the dynamic spectrum access (DSA) and cognitive radio (CR) literature. Often, however, the functionality and performance of such algorithms are validated against theoretical calculations using only simulations. Both the theoretical calculations and simulations come with their attendant sets of assumptions. For instance, designers...
Spectrum sharing is a promising technique responsible for providing efficient and fair spectrum allocation. Considering the unevenness phenomenon of spectrum usage in industrial wireless networks, a novel spectrum sharing scheme, in the framework of industrial cognitive radio network (ICRN), is proposed in this paper via an autonomous switching technique to equalize the spectrum usage and increase...
Sensor networks usually complete several data processing tasks that include the acquiring sensor samples, preparing messages containing data, and sending/receiving radio messages. In this paper, we consider the impact of the sensing subsystem, intended for area monitoring applications, and its effect on the power consumption of sensor networks. We describe a sensing subsystem with implemented power...
The embedded system innovation has the close and indivisible relationship with the environment science aesthetics. This paper deals with a simple, easy to install, microcontroller-based circuit to monitor and record the value of temperature, humidity, soil moisture and sunlight of the natural environment that are continuously modified and controlled in order optimize them to achieve maximum plant...
Reconfiguration plays a vital role in resource utilization. The functional, interconnect testing of digital circuits is done using Boundary Scan Trainer (BST) kit. The faulty cores if replaced by spare ones in real time reduce the switching time. This procedure is implemented in wireless network system also. The proposed work focuses on wireless communication among nodes, grouping them as different...
