Special Issue Information

Dear Colleagues,

In recent years, technology has grown in an immensely phosphorus way, with sophisticated devices providing a greatly effective acceleration in communication technologies. Wireless sensor networks (WSNs) comprise a wide array of distributed equipment and autonomous devices that can monitor or predict physical and environmental conditions cooperatively. These ever-evolving networks have a wide demand in the current market, taking inputs from smart dust, mobile applications, desktops, as well as clusters. WSNs face many challenges and issues mainly caused by communication failures and the storage of data with computational constraints. These wireless sensor networks are low-powered embedded components implemented for real-time perceiving, producing data to specified targets. WSNs provide an adaptive mechanism for the exhibition of intelligent behaviour through artificial intelligence to solve complex and dynamic problems faced by end users.

WSNs have the flexibility to fetch logs against autonomous users to analyse key issues with the help of topological change, robustness and communication failures. They are considered self-organised and damage-proof in various fields such as agriculture, healthcare, and military and navy aviation.

Researchers have discovered many suitable solutions for communication issue, which is in the beginning stage called the location awareness of WSNs. This location awareness provides a position functionality which is like a global position system (GPS) that is used to fetch the location of users through their current location; through this approach, the user can obtain a high frequency, even indoors. This internally works with multiple algorithms, such as the DV–HOP algorithm, centroid algorithm and ATIP algorithm. It targets the hop distance separating the anchor nodes and target nodes; hence, calculating the overall distance. The reason for using the algorithm inside the sensor networks is that the algorithm has the capability of avoiding errors from any other additional hardwired technologies. Inducing data fusion is the obtainment of a high frequency and the tracking of a user’s location at any time. The main method of using sensor products as a technology with data fusion is sniper detection systems, smart dust, and military applications such as military commands, surveillance, and targeting systems. Since it is a low-cost sensing technology, most of the equipment is covered by the sensing objects. These are also used for much environmental research, such as volcano detection, weather-sensing technologies, early flood detection processed and mainly health applications. The sensor objects included in the data fusion of health applications are often used in artificial retinas, including many other applications. As per the data mining analysis, the data are sent by a signal to the devices and the data fusion acts as an interface by converting the analogy code to digital code, which is then sent to the microcontroller; then, the frequency is given to the radio interface. This Special Issue provides an opportunity for researchers and technologists to promote future research concerning the development of technology for the provision of efficient digital solutions and strategies to combat the current sensing methodologies with the use of data fusion.

Topics of interest include:

  • Technological strategies for the effective management of data fusion;
  • Role of digital sensing technologies in public health surveillance;
  • The role of data fusion systems in managing communication challenges;
  • Technological strategies to overcome the conflict issue in sensing applications;
  • System model and cluster formation in data fusion;
  • Structural architecture to be adapted in WSNs for technical issues;
  • Adaptive algorithms used in fusion technologies for WSNs;
  • Data transformation on dynamic topologies in mining technologies;
  • Level of abstraction in data fusion with source relationship;
  • Fusion-based input source relationship in sensor networks;
  • Innovative ideas in discussion layers of fusion;
  • Sensors, real-time applications, and data fusion in smart dust.

An XYZ compliant micropositioner has been widely mentioned in precision engineering, but the displacements in the X, Y, and Z directions are often not the same. In this study, a design and optimization for a new XYZ micropositioner are developed to obtain three same displacements in three axes. The proposed micropositioner is a planar mechanism whose advantage is a generation of three motions with only two actuators. In the design strategy, the proposed micropositioner is designed by a combination of a symmetrical four-lever displacement amplifier, a symmetrical parallel guiding mechanism, and a symmetrical parallel redirection mechanism. The Z-shaped hinges are used to gain motion in the Z-axis displacement. Four flexure right-circular hinges are combined with two rigid joints and two flexure leaf hinges to permit two large X-and-Y displacements. The symmetrical four-lever displacement amplifier is designed to increase the micropositioner’s travel. The displacement sensor is built by embedding the strain gauges on the hinges of the micropositioner, which is developed to measure the travel of the micropositioner. The behaviors and performances of the micropositioner are modeled by using the Taguchi-based response surface methodology. Additionally, the geometrical factors of the XYZ micropositioner are optimized by teaching–learning-based optimization. The optimized design parameters are defined with an A of 0.9 mm, a B of 0.8 mm, a C of 0.57 mm, and a D of 0.7 mm. The safety factor gains 1.85, while the displacement achieves 515.7278 µm. The developed micropositioner is a potential option for biomedical sample testing in a nanoindentation system. Full article
