The rectangular Horn–shaped wearable microstrip patch antenna is designed to resonate in the ISM (Industrial, Scientific, and Medical) band and other commercial wireless applications.The proposed multiband antenna is a wearable textile antenna with jeans material used as a substrate having relative permittivity, εr of 1.6. The physical dimensions of the antenna is 50 × 80 × 0.56 mm³. To generate the desired antenna to be applicable in ISM band, the slots are etched in the form of horn in the patch and the slotted ground plane is incorporated. The antenna provides percentage bandwidth of 44.3% at 2.4 GHz and 18.35% at 4.6 GHz.The antenna gain values are 4.74 dB and 3.71 dB at 2.45 GHz and 5 GHz frequencies respectively and VSWR is 1.21 at 2.45 GHz. The proposed wearable textile antenna is experimentally validated to be applicable for ISM band (2.4–2.484 GHz), WiFi (2.45 GHz), WiMax (3.3–3.9 GHz) and C-band (6.57–6.8 GHz) applications.
Wireless sensor networks (WSNs) are being utilized widely in many different industries, including agriculture, medicine, and the military. They contain many distributed sensors to monitor physical or environmental factors, such as temperature, humidity, pressure, etc. and use various communication technologies, including WiFi, radio frequency (RF), Bluetooth, and ZigBee. ZigBee is always a preferred choice for applications in WSNs. ZigBee has remarkable capabilities, such as saving energy and transmitting data over long distances. ZigBee end devices, as well as a ZigBee coordinator (ZC) and a ZigBee router (ZR), are crucial components of the WSNs. This article discusses the fundamentals of the ZigBee network, one of the most popular data transmission technologies in wireless sensor networks (WSNs). Additionally, we want to discuss the ZigBee communication technologies and their applications, particularly in the networks. Different scenarios for mobile agents including their routing protocols in WSNs are considered. Simulation results of different scenarios demonstrate how easily scalability can be achieved and provide a foundation for further ZigBee application development. At last, some conclusions and ideas are presented for considerations.
Wireless Medical Sensor (WMSN) networks have become a great technology to allow for the best kind of applications. Recent developments at WMSN have helped to create a comprehensive health monitoring concept in both home and hospital care settings. Current technological advances in sensors, integrated dynamic circuits, and wireless connectivity have allowed the event of smaller, heavier, less expensive, and clever body sensors. These modules are able to hear, process, and communicate with one or more important signals. In addition, they will be used on local wireless networks (WPANs) or wireless nerve networks (WBSNs) to monitor health. Many studies are being conducted and/or ongoing to develop flexible, reliable, secure, realistic, and effective WBSNs for health applications. The importance of wireless nerve networks in health surveillance is constantly evolving, due to the growing need for safety and security in cities. The rapid development of wireless technology has significantly aided the advancement of monitoring systems that have been developed through the combination of wireless sensors. The wireless health monitoring introduces emerging innovations with significant advantages when compare to conventional communication networks, which has the advantages of lowering the cost of installation and maintenance while increasing the effectiveness of the health monitoring system in the field of medicine.
