Cognitive radio (CR) technology is being applied to many different communications systems. By providing the ability of spectrum sharing, CR technology allows for improved commercial data services, and allowing for new unlicensed services to operate in pre-allocated bands in an opportunistic manner as secondary users.the study the possibility of increasing the utilization of the TV band by allowing WiMax to share this band as a secondary user. TV band was chosen since it is known to be underutilized, making it a prime candidate for applying CR technology. In the study, employed Dynamic...

The Wireless Body Sensor Network (WBSN) is a wireless network used for communication among sensor nodes operating on or inside the human body in order to monitor vital body parameters and movements. The design and the development of such systems for health monitoring have gained a lot of attention recently in both the research and the industry. Mainly motivated by the increasing of healthcare costs and propelled by the recent advances in the development of miniature health monitoring devices. This project presents a preventive health care system with a flexible design. By using Heartbeat...

This summary is to simplify the attendance recorder system by using Radio Frequency Identification (RFID) technology. RFID based Parent SMS Alert and Attendance System is a web based application that will be developed to overcome this problem. With the RFID kit.The systems also have integrated with the RFID Database Handling System for a fully functional system. The information from RFID Database handling System will be used for attendance and for SMS Alert also.Main idea of the approach is to reduce manual work and to automate the attendance system the attendance system is an embedded one....

The Internet of Things (IoT) connects devices into an intelligent, interconnected network, offering convenience and efficiency but also introducing significant vulnerabilities. This discussion highlights IoT hardware weaknesses, emphasizing risks to devices, networks, users, and systems. While unauthorized access to sensitive information is a common concern, safety risks-such as compromised cars, drones, or medical devices-are even more alarming. IoT's growth has empowered hackers, exemplified by a DDoS attack that disrupted internet services across the U.S. East Coast, affecting major...

L'Internet des objets (IoT) connecte des appareils dans un réseau intelligent et interconnecté, offrant commodité et efficacité, mais introduisant également des vulnérabilités significatives. Cette discussion met en évidence les faiblesses du matériel de l'IdO, en insistant sur les risques pour les appareils, les réseaux, les utilisateurs et les systèmes. Si l'accès non autorisé à des informations sensibles est une préoccupation courante, les risques pour la sécurité - tels que des voitures, des drones ou des appareils médicaux compromis - sont encore plus alarmants. La...

Das Internet der Dinge (IoT) verbindet Geräte zu einem intelligenten, vernetzten Netzwerk, das Komfort und Effizienz bietet, aber auch erhebliche Schwachstellen aufweist. In dieser Diskussion werden die Schwachstellen der IoT-Hardware hervorgehoben, wobei die Risiken für Geräte, Netzwerke, Benutzer und Systeme im Vordergrund stehen. Während der unbefugte Zugriff auf vertrauliche Daten ein weit verbreitetes Problem darstellt, sind Sicherheitsrisiken - wie z. B. kompromittierte Autos, Drohnen oder medizinische Geräte - sogar noch alarmierender. Das Wachstum des IoT hat Hackern Auftrieb...
