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....
