The challenges to deal with to design a WSN node which can be used in safety-relevant application are, to the present day, still to be completely investigated and solved. Nevertheless, a prototype implementation is presented in this paper, with an emphasis on the chosen hardware architecture and components, highlighting the limitations imposed by specific choices. Furthermore, an example application...
In this demo, we introduce a new sensor node for underground monitoring called the MoleNet. The MoleNet is designed especially for wireless underground operation. The development of the platform is part of a revitalization project in Cameroon. Due to certain constraints, the project terrain requires a complete underground deployment of the soil monitoring system. The underground channel is quite different...
The main goal of this paper is to propose a simple and low-cost microcontroller-based laser communication link. To demonstrate that laser communication is a viable and efficient means for transmitting data, a transceiver capable of transfer rates of approximately 0.7 kB/s is prototyped. The hardware used for the transceiver consists of Commercial Off-The-Shelf (COTS) lasers, photodiodes, and the Arduino...
To understand the utilization of clinical resources and improve the efficiency of healthcare, it is often necessary to accurately locate patients and doctors in a healthcare facility. However, existing tracking methods, such as GPS, Wi-Fi and RFID, have technological drawbacks or impose significant costs, thus limiting their applications in many clinical environments, especially those with indoor...
Remote monitoring system is a part of Internet of Thing (IoT) application whether in healthcare, logistic or even agriculture. The system consists of several nodes including wireless sensor node which is a compulsory end-device part in remote monitoring system for data acquisition and processing. This paper discusses the available design of wireless sensor node from different hardware and interfaces,...
This paper describes a low power communication architecture for 2U class nano-satellites. The system is designed to operate two links in the UHF and VHF bands, each of which is managed by independent microcontrollers. Impedance matching networks and harmonic filters are designed to ensure that the maximum power is transferred and spurious emissions are within the acceptable limits. It contains a transceiver...
The network of nodes with sensing technology and wireless capability is termed as Wireless Sensor Network (WSN). WSN has high potential to adapt to the changes of how we live. Its budding technology makes the motes communicate with each other efficiently. The sensor nodes in WSN are referred as motes and they form the main building blocks for creating a network. The motes need to work efficiently...
Severe stress urinary incontinence is a nonnegligible complication that affects men as well as women. When initial therapies are not sufficient, implantation of artificial urinary sphincters (AUS) is considered the gold standard treatment. This hydromechanical device applies constant pressure on the urethra to keep urine inside the bladder. Although recovery from incontinence is full or partial, this...
Existing aircraft tracking capability is lacking when encountered with water, in the event that aircraft crashes into the ocean. This paper presents an aircraft tracking system that able to track the attached aircraft in real time. The information of the location collected is presented on a web-based GUI. The proposed system is intended to be used as a standalone tracker that is able to keep track...
This paper represents the smart system that bypasses the normal functioning algorithm of traffic lights, triggers a green light when the lights are red or to reset the timer of the traffic lights when they are about to turn red. Different pieces of hardware like microcontroller units, transceivers, resistors, diode, LEDs, digital compass and accelerometer will be coupled together and programmed to...
The Pulsar IIb is a general purpose FPGA-based processor board designed for full mesh ATCA backplanes. This hardware was originally designed to support Level-1 silicon track trigger R&D projects at the LHC. Each ATCA carrier board is required to support the Intelligent Platform Management Interface (IPMI) protocol, which is responsible for coordinating hot swap operations and for exchanging sensor...
Visible Light Communication (VLC) Technology is the short range optical wireless communication technology using LEDs for communication and illumination. In this paper, we propose a repeater system for visible light communication to extend the coverage. Our proposed repeater system is composed of hardware and software components. The transmitter converts text data sending from the user into light signal...
Due to the extreme fast movement of traffic in the busy localities, the cases of road accidents are increasing day by day. Traffic Control Board made different speed limit for different places to limit the speed, but it is not possible to always monitor the infringements manually due to several factors.
Home automation systems aim to control all home activities and functionalities. Control can be done through a remote control that sends command signals wirelessly by means of infrared radiation, Bluetooth connectivity, or any other RF technology as well as via internet or GSM communication. The controlled target devices usually include domestic appliances, security and safety systems, HVAC systems,...
In the recent times it has been seen that wireless network is established with the help of nodes and used them as a monitoring system. But the problem arises that the traffic each node handles is of great extent. Also the security and efficiency in working in emergency situations is very low. It has a limitation over worldwide access everywhere due to non-standardized communication between multiple...
Two power saving schemes namely power management and power control have been investigated in isolation for addressing power constraint of wireless sensor networks, which is known to be the most prominent limitation in road to successful deployment of wireless sensor networks. However, combining the power saving schemes is yet to be investigated in the literature. Therefore, in this paper, we propose...

The modular concept is easily adjusted to react to differing conditions. Energy consumption and experiment results, under...
Wireless Sensor Network using many wireless communication protocols, such as Bluetooth, ZigBee, ultra wideband, and wifi. Wifi has the advantages of high data rate and long range distances, but it requires a great power. While ZigBee has the advantages that it uses less power, but the resulting low data rate and short range distances. With respective these advantages and disadvantages, this paper...
