Recent advances in technologies have allowed the design of small-size low-power and low-cost devices that can be connected to the Internet, enabling the emerging paradigm of Internet-of-things (IoT). IoT covers an ever-increasing range of applications, e.g., health-care monitoring, smart homes and buildings, etc. In this invited paper, we discuss and summarize the IoT paradigm with a special focus...
The paper addresses an area coverage problem by using rotatable cameras in wireless camera sensor networks. It has been recognized as an important issue not only to effectively cover an area of interest without holes but also to identify the object invaded the area by cameras in wireless camera sensor networks. Therefore, this paper presents a Full-View Area Coverage (FVAC) scheme to effectively deploy...
The rapid increase of modern wireless technology opens the door for several new applications using the Internet of Things (IoT) technology. In an educational environment, students depend on the transit bus system for their daily routine and there is a high demand of people to be served by buses around university campuses in the United States of America. Often times, the members of university communities...
For powering small wireless IoT nodes, compact, efficient rectifying antennas have been realized. A first design for 868 and 915 MHz is described. Based on the lessons learned, a new design for 2.45 GHz is realized that is a factor 13 smaller in size.
This study proposes a simple method for creating flat beam patterns in a near-field. In radio-wave transmission, the near-field beam efficiency of the beam-type wireless power transfer (WPT) system theoretically reaches 100%, but the beam pattern is not flat in the near field. In real beam-type WPT systems, the total beam efficiency (DC-RF-transmission, beam efficiency, and RF-DC conversion) can be...
A group of wireless devices with the ability to sense physical events (sensors) or/and to perform relatively complicated actions (actors), is referred to as Wireless Sensor and Actor Network (WSAN). In this work, we propose and implement two Fuzzy Based Actor Selection Systems (FBASS): FBASS1 and FBASS2 for actor selection in WSANs. The systems decide whether the actor will be selected for the required...
Industrial Internet of things (IIoTs) relies on different devices working together, gathering and sharing data using multiple communication protocols. This heterogeneity becomes a hindrance in the development of architectures that can support applications operating independently of the underlying protocols. Therefore in this paper, we proposed a modular and scalable architecture based on lightweight...
This paper presents a new principle of a passive chipless RFID wireless sensor for a rotational motion measurement and identification. The sensing and identification principles are based on a high quality factor substrate integrated cavity (SIW) resonator with dual antennas at two different angles. Depending on the angle difference between the dual antennas, the backscattered power generates a unique...
In this study, a wireless and passive displacement/strain sensing system is proposed for structural health monitoring (SHM). The wireless and passive interrogation of the sensing unit [a variant of a nested split-ring resonator (NSRR)] is achieved through the near-field interaction and electromagnetic coupling between the single antenna in the system and the multiple sensors called the NSRR probes...
The future healthcare systems' growth and development have greater dependence on Wireless Body Area Network (WBAN). Notwithstanding, the utilization of untrustworthy methods has made it defenseless against various attacks. These attacks can be kept under check by utilizing different security procedures. For this reason a security protocol named Se-Small is utilized. The procedure includes signing...
Emotion Recognition has expanding significance in helping human-PC collaboration issues. It is a difficult task to understand how other people feel but it becomes even worse to perceive these emotions through a computer. With the advancement in technology and increase in application of artificial intelligence, it has become a necessity to automatically recognize the emotions of the user for the human-computer...
This paper focuses on Microcontroller and advanced embedded software based product to get the alarm at the control room. When the vibration level is high in Cooling Fan mounted at the Cooling tower of the Thermal power plant, vibration switches are operated which is sensed by the Transmitter. The transmitter will transmit the signal in the form of Messages to the Receiver, which gives the audio &...
We propose a system in which it allows the user to contact or make an alert during any emergency situation to the appropriate service provider directly using this application. Though there are several apps in the market, what makes our application special is that it is completely in our Tamil language. Here the user has to download and install the application along with all the required details. In...
When the use of wireless sensors network is becoming increasingly wider and deeper, its problems are also beginning to highlight. Due to the limit of wireless sensors' energy supply and the unstable channel, ensuring the reliability and speed of the transmission has become the research hot spot. With multipath or retransmission transmission mechanism, the redundancy of data transmission can be ensured...
Glaucoma is an eye disease, where the elevated level of intraocular pressure (IOP) in the anterior chamber of the eye can damage the optic nerve causing irreversible blindness [1]. An IOP monitoring microsystem (IMM) implanted in the interior chamber of the eye is required to take frequent IOP measurements to account for its diurnal variation and dependency on the body posture, which is not possible...
Due to the increased dependency on fusion of heterogeneous technologies, there is an increased demand for better provisioning of utility services such as electricity, water, and telecommunication, from end- users. Such demand has put more pressure to preserve the over-utilized natural resources such as water, energy, and RF spectrum. Energy and water are the precious key resources provided to us in...
With the advancement in sensing technology, applications are moving from wired to wireless region. The main challenge is the energy consumption of individual sensing nodes. When first node dies system becomes unstable and we cannot make use of the untapped node's energy. There comes the relevance of TSEP like protocols in such heterogeneous network. Heterogeneous in the sense with respect to node...
