Condition monitoring (CM) of gearbox is a crucial activity due to its importance in power transmission for many industrial applications. Monitoring temperature is an effective mean to collect useful information about the healthy conditions of the gearbox. This study investigates the use of a novel wireless temperature node to monitor and diagnose different faults on a gearbox transmission system under...
Internet-of-things (IoT) paradigm exploits the Distributed Measurement System (DMS) to execute measurements. Each node of the DMS has computational and communicative capabilities, and can be equipped by sensors and measurement instruments. Therefore, it can be assumed as Smart Object (SO). The availability of mobile SO (MSO) (cars, smartphones, drones) is taken into consideration in the research to...
The work presents the results of a project concerning the study and the prototypal realization of an innovative low cost module for Structural Health Monitoring (SHM) that would allow the measurement of internal displacements inside civil structures. A set of these sensors could also be part of wide Wireless Sensor Network (WSN). The basic working principle of the sensor is the Hall Effect. This effect...
The general structure and main principles of creating a multi-version post-severe NPP accident monitoring system, which consists of one wired and three drone-based wireless network subsystems, are proposed. Reliability block diagrams for the system are built. On the basis of the reliability block diagrams, reliability models of the system are developed. The dependence on probability of failure-free...
The increasing popularity of automation has resulted in the development of “Smart Homes”. These “smart” systems are developed with the aid of sensors that provide the information required of the systems to make informed decision. this paper presents the design of a system that allows users to remotely monitor and interact with the sensor nodes in the system using their smartphone. The proposed system...
For the WSNs lifetime optimization, the non-disjoint set covers (NDSC) based coverage control approach has brought out a better performance. In addition, it yields a promising indicators in term of reliability, resilience and the possibility to be used for heterogeneous WSNs. This paper addresses the WSNs resiliency assessment via NDSC approaches to WSNs lifetime optimization. We investigated the...
In this paper, we describe a 920 MHz band long range wireless SAW passive tag system (WSPTS) for vibration monitoring, which achieves more than 10m reading distance. For the purpose of structural health monitoring (SHM) of aging infrastructures (e.g. bridge, building, and so forth), passive wireless sensor systems are an attractive option because they are operated battery-less and almost maintenance...
In this paper, we describe a 920 MHz band long range wireless SAW passive tag system (WSPTS) for vibration monitoring, which achieves more than 15 m reading distance. For the purpose of structural health monitoring (SHM) of aging infrastructures (e.g. bridge, building, and so forth), passive wireless sensor systems are an attractive option because they are operated battery-less and almost maintenance...
The paper presents the design and implementation of an integrated wireless network that support to the multiparametric geophysical monitoring network of the Campi Flegrei volcanic area. The wireless network is equipped with a tool for real-time monitoring and fault detection. The enhancement of the transmission system with respect to the previously existing one has been realized in view of the increased...
Telemetrie Body Area Network (TBAN) system is one of the useful methods to realize improving user's body behavior and monitoring health condition. Not only showing physical parameters, by feedback of vital information to user, TBAN system is extended to the autonomous system closed to user. Getting such information, user is able to improve his body behavior consciously. Moreover, telemetric function...
Being able to monitor the body condition and health condition of the user telemetrically is a very important for caring the user. Vital signs and the body posture is an important aspect to judge the danger of the user. Body posture will change frequently where body state transition should be done inside the system. By running this system autonomously, it will blend in the human daily life and raise...
A chipless RFID sensor exploiting the depolarizing effect of a finite period surface is proposed for rotation monitoring. The information is encoded in the cross-polar response of the scatterer, which, in turns, depends on the orientation of the chipless RFID tag with respect to the probing wave. Preliminary assessment is illustrated and critical issues are analyzed for future developments.
We explore techniques that can be used to reduce the power consumption of gateways in wireless sensor networks deployed in environment monitoring applications, such as Automatic Weather Stations (AWS). The challenge is the deployment of these networks in locations that are far from a consistent power source, such as a national grid. Such stations must be autonomous and power consumption must be minimized...
Due to climate change and scarcity of water reservoirs, monitoring and control of irrigation systems is now becoming a major focal area for researchers in Cyber-Physical Systems (CPS). Wireless Sensor Networks (WSNs) are rapidly finding their way in the field of irrigation and play the key role as data gathering technology in the domain of IoT and CPS. They are efficient for reliable monitoring, giving...

In last few decades, as a result of the advances in microelectromechanical systems, Wireless Sensor Networks (WSNs) have gained a considerable attention due to their low-cost, low-power and small-scale sensor nodes which are used to integrate sensing, processing, communicating capabilities to solve many different real world problems. The placement of sensor nodes is a very important step to cover...
Our daily life is characterized by countless human relationships. Every day we go to work, do shopping, partake in leisure time. At the base, there are some choices that lead us to make a series of activities; In which we interact and relate with many people. What influences the choices we make? Answering this question can be a very daunting task. However, it can help us to identify the main key elements...
In many security systems, it is sufficient to monitor a certain territory with the same type of devices in such a way that each point of the territory falls into the coverage area of at least one device while minimizing the energy consumption of the devices. However, in some security systems, it is necessary to observe objects from a certain side. For example, to identify a person you need to see...
The advances in wireless low-power sensors and the increasing demand for portable healthcare monitoring systems have inspired the realization of Wireless Body Sensor Networks (WBSNs). IEEE Std. 802.15.6 defines the communication protocol for WBSN applications in terms of physical and medium access layers. The high generality and flexibility of standard requirements poses the question of how WBSN parameters,...
