Automation of modern industrial plants require real-time tracking of object locations and sensing of local and ambient parameters for variety of applications such as counting and tracking of objects in assembly line, detection and positioning of failures of machines etc. Mostly, discrete Real Time Location System (RTLS) performs object tracking in existing industrial automation without its integration...
This paper presents the overall design of the hot spot detection and air flow control for a wall-mounted air-conditioner system. The system is designed to find out the hot areas that will cause the cool air from the air-conditioner not equally distributed to all areas in a room. Therefore, one of the solutions is to control airflow of the air-conditioner so that the cool air could reach to that particular...
This paper presents a novel wearable biomedical Network on Chip (NoC) concept development to monitor and predict irregular brain waves as advanced sensitive portable for an electroencephalogram (EEG) analysis device. The proposed device will monitor brain’s spontaneous electrical activity in normal and abnormal situations for specific patients suffering from different types of epilepsy...
In this paper, we propose BAN-GZKP that optimizes the best to date secure lightweight and energy efficient authentication scheme, BANZKP, designed for WBAN networks. BANZKP is vulnerable to several security attacks such as the replay attack, DDoS attacks at sink and redundancy information crack. Also BANZKP needs an end-to-end authentication which is not compliant with the human body postural mobility...
A wireless monitoring system, which operates autonomously for up to several years, is discussed. Measurement techniques for temperature and humidity, acceleration and strain are reviewed. Data transmission is carried out by RFID and Bluetooth radio interfaces. The operation algorithm of the wireless monitoring system is reported.
This paper investigates resource allocation in a multi-user, multi-band and multi-antenna equipped wireless communication system, which is used for simultaneous wireless information and power transmission (SWIPT). The optimization problems of sum-rate over multiple sub-bands subject to the power spectral density requirement (PSDR) limit and the circuit power requirement (CPR) are studied in the case...
We propose a wireless power transfer (WPT) based underlay spectrum sharing scheme, where a primary user (PU) needs to harvest wireless energy from an access point (AP) and then transmit its data to AP using the harvested energy. In the same area, a secondary transmitter (ST) intends to communicate with a secondary receiver (SR). The secondary data can be transmitted along with the WPT, which can on...
With the ability to reconstruct signals from a highly incomplete number of samples, Compressive Sensing (CS) has been proposed in bandwidth-constrained scenarios like remote sensing, where signals exist some degree of redundancy. In CS, reconstruction approaches are of great importance. However, current reconstruction approaches are of highly computational complexity because they use greedy or convex...
In this paper, different energy harvesting solutions for an autonomous miniature wireless sensing node are invista-gated. The communication part is realized with Low Power Wide Area Network (LP-WAN) LoRa technology that combine low-power and long range capabilities. Solar, Thermal and Piezo harvesting techniques are compared for autonomous sensing application.
This paper studies the physical layer security of uplink (UL) transmission in simultaneous wireless information and power transfer (SWIPT) deployed in wireless sensor networks (WSNs). Firstly, we model the random network as Poisson cluster process (PCP) to focus on the case where eavesdroppers hide around certain targets to intercept the confidential information successfully. Then, the communication...
Abnormal activity sensing has attracted increasing research attention in military surveillance, patient monitoring, and health care of children and elderly, etc. Researchers have exploited the characteristics of wireless signals to sense “keystrokes” and “human talks”, relieving the privacy invasion concern caused by mounting the surveillance cameras or wearing the smart devices. However, existing...
The ever increasing number of people who need continuous medical attention coupled with the rising costs of healthcare have triggered the concept of remote patient monitoring. This can be achieved using wireless sensor nodes attached to the human body. Such technology is mainly limited by the amount of available energy. Thus efficient power consumption estimation in the early stage of the design is...
The concept of Radio Frequency (RF) fingerprinting is that electronic devices can be identified and authenticated through their radio frequency emissions, which contain intrinsic features of the device itself. RF fingerprinting can be used to enhance the security of wireless networks because the fingerprints provide a form of authentication. In previous research papers, the RF fingerprints have typically...
The continuous transfer of messages in vehicular ad hoc networks leads to a heavy network traffic load. This causes congestion in the wireless channel which degrades the reliability of the network and significantly affects the Quality of Service (QoS) parameters such as packet loss, throughput and average delay. Therefore, it is vital to adapt the transmitting data rates in a way that ensure that...
Wireless multimedia sensor networks (WMSNs) require data to be communicated timely and reliably. However, radio transmission errors incurred by wireless channel make it difficult to achieve these qualities simultaneously. To provide good quality of service (QoS) of WMSNs, parameters associated with the WMSNs need to be studied completely and best tradeoff needs to be made. To characterize the delay-reliability...

This type of wireless resonant EV charger...
Wireless Sensor Network (WSN) acts as one of the fundamental elements of network infrastructure, requiring to establish a wireless communication network for the reliable frame transmission.

However, the contention collision of typical technique, IEEE 802.15.4, could not guarantee...
Data delivery in low power and lossy networks like Wireless Sensor Networks (WSN), which has a significant role in Internet of Things (IoT), is vital due to the high probability of packet loss due to wireless and constrained environment. Data caching and transmission rate control are independent ways of improving the performance of transport protocols in WSN by immediately responding to packet losses...
Recent research on Low Power Wide Area Network (LPWAN) technologies which provide the capability of serving massive low power devices simultaneously has been very attractive.
